Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an embodiment of the present invention, a method for controlling an automobile is provided, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The automobile control method may include: step S110 to step S130.
At step S110, a current temperature of an air compressor in a pneumatic system of the automobile is acquired.
At step S120, it is determined whether the current temperature of the air compressor is greater than a set temperature threshold.
In step S130, if the current temperature of the air compressor is greater than the set temperature threshold, the stored gas is delivered to the air compressor to cool the air compressor. The stored gas is pre-stored gas with temperature in a set temperature range and/or pressure in a set pressure range. For example: the upper limit of the set temperature range may be smaller than the set temperature threshold.
For example: through ECU control solenoid valve break-make condition, make this gas circuit system air pressure control in suitable within range to air compressor carries out the cooling treatment, can solve the air compressor machine heat dissipation not good, prevents that air compressor machine during operation casing temperature is too high, leads to the problem of air compressor machine damage. The problem of waste of exhaust energy of the gas path system can be solved.
Therefore, the stored gas is conveyed to the air compressor under the condition that the current temperature of the air compressor is greater than the set temperature threshold value, so that the stored gas is utilized to cool the air compressor to reduce the temperature of the air compressor, the air compressor is prevented from being broken down or damaged due to overhigh temperature, and the working reliability and safety of the air compressor are improved.
Alternatively, the step S130 of delivering the stored gas to the air compressor may include: the exhaust pipeline of the preset air storage cylinder is controlled to be opened so as to convey the stored gas stored in the preset air storage cylinder to the air compressor, and the stored gas stored in the preset air storage cylinder is utilized to cool the air compressor. For example: an exhaust valve, such as an exhaust solenoid valve, is arranged in the exhaust pipeline of the preset air cylinder and can control the opening of the exhaust valve in the exhaust pipeline of the preset air cylinder. The ECU detects the pressure of the air storage cylinder, the exhaust solenoid valve is opened after the preset pressure is reached, and the low-temperature gas is used for cooling the air compressor by utilizing the principles of forced convection and gas expansion heat absorption.
That is, in the case where the preset gas cylinder may include a recovery gas cylinder, delivering the storage gas to the air compressor may include: under the condition that the current temperature of the air compressor is greater than a set temperature threshold value, directly controlling an exhaust pipeline of the preset air storage cylinder to be opened so as to convey stored gas to the air compressor.
Wherein, in presetting the gas receiver, it has storage gas to store in advance to when air compressor need cool down the processing, utilize the storage gas of storing in advance in presetting the gas receiver to cool down the processing to air compressor.
For example: the exhaust energy of each air path system on the vehicle can be recovered by using the low-pressure air cylinder and the exhaust air path, the pressure condition of the low-pressure air cylinder is detected by using a pressure sensor (or a pressure switch), the exhaust electromagnetic valve of the ECU (electronic control unit) for controlling 2/2 is used for carrying out centralized exhaust, and the exhaust port of the air path is arranged at the air compressor. Exhaust control ECU real-time acquisition of air compressor temperature TCOMWhen T isCOMGreater than a preset temperature value TSETWhen the solenoid valve for exhaust 2/2 is turned on (i.e., the two-way solenoid valve for exhaust) to perform exhaust.
From this, predetermine the storage gas of storing in the gas receiver and carry to air compressor department through the control, realize the cooling of air compressor and handle, simple and convenient and reliable.
More optionally, the output port of the exhaust pipeline of the preset air storage cylinder is arranged towards the heat generating area or the set temperature area of the air compressor.
For example: the exhaust port of the pipeline system faces the highest temperature position of the air compressor, the air compressor can be cooled by utilizing the forced convection phenomenon, in addition, the exhaust gas temperature of the exhaust port of the pipeline system is lower by utilizing the principle that gas expands and absorbs heat from a high pressure side to a low pressure side, and when the exhaust port of the pipeline system exchanges heat with the air compressor, the air compressor can be further cooled.
From this, through making the delivery outlet of predetermineeing the air receiver towards air compressor's the regional or set for temperature region etc. transport storage gas that generates heat, can promote cooling efficiency to save storage gas.
Optionally, the preset air cylinder may include: a spare air reservoir and/or a recovery air reservoir. For example: the preset air cylinder can comprise: a reserve air reservoir that may be used to store a reserve gas, and/or a recovery air reservoir that may be used to store a recovery gas.
Wherein, reserve air receiver can be used for storing reserve gas in advance to the reserve gas that utilizes the storage cools down air compressor.
The recovery air cylinder can be used for recovering and storing the exhaust gas of an exhaust system of an automobile in the exhaust process of the exhaust system in a pneumatic system of the automobile so as to cool an air compressor by utilizing the recovered and stored exhaust gas.
That is, the stored gas is delivered to the air compressor, and may include a plurality of delivery processes, such as a first delivery process, a second delivery process, and the like, and particularly, refer to the following description.
Specifically, the exhaust pipe of the preset backup air reservoir may be controlled to be opened, so that the backup air stored in the backup air reservoir is delivered to the air compressor as the stored air. For example: and the standby gas stored in the standby air storage cylinder is used as the storage gas through the opened exhaust valve of the standby air storage cylinder and is conveyed to the air compressor. Wherein, reserve air receiver can be the air storage equipment that can be used for cooling down to air compressor that sets up in advance, has stored in advance in reserve air receiver and can be used for the low temperature and/or the low pressure gas that the air compressor cooled down.
Specifically, the exhaust pipe of the preset recovery gas cylinder can be controlled to be opened so as to convey the recovered gas stored in the recovery gas cylinder to the air compressor as the stored gas.
For example: automobile pneumatic system parts (such as air suspension)When exhausting, the high-pressure gas that will discharge is gathered and is collected, and the pressure in the low pressure gas receiver rises gradually this moment. The exhaust control is started and the ECU starts operating. If in the form of a pipeline, the exhaust gas of the pneumatic system of the whole vehicle is recovered and is only stored in a low-pressure air storage cylinder in a one-way mode (the pressure P of the air storage cylinder)L< pressure P of the solenoid valven) The exhaust part of the pneumatic system is subjected to optimization treatment of centralized control, the pipeline exhaust port is arranged at the air compressor, and finally the exhaust control ECU controls the exhaust time sequence to cool the air compressor.
For example: can retrieve whole car pneumatic system's exhaust through the pipeline, the storage is in the air receiver, carry out the centralized processing optimization to pneumatic system exhaust part's logic, and use ECU control air receiver outside (atmosphere) exhaust, the gas vent of this system is facing to air compressor highest temperature department, utilize forced convection phenomenon can cool down air compressor, in addition, utilize the gas from high-pressure side to the endothermic principle of low pressure side inflation, the gas temperature of gas vent exhaust of this system is lower, when carrying out the heat exchange with air compressor, can go on further cooling to air compressor. The exhaust gas of the whole vehicle pneumatic system is recovered through a pipeline and stored in an air storage cylinder. Therefore, the air displacement of the whole vehicle pneumatic system is different by using the thinking of zero storage and retrieval, the recyclable energy is different, and the air storage cylinder is used for storing air, so that the energy of each part of the pneumatic system can be concentrated and utilized.
Therefore, the stored gas is stored in various gas storage modes, so that the stored gas is more convenient and flexible to cool the air compressor.
Optionally, in the case that the stored gas stored in the preset gas cylinder is used to cool the air compressor, especially in the case that the preset gas cylinder may include a recovery gas cylinder, the step S130 of delivering the stored gas to the air compressor may further include: and carrying out the conveying control process according to the pressure of the stored gas.
The following further describes a specific process of performing the transportation control according to the pressure of the stored gas, with reference to a schematic flow chart of an embodiment of the transportation control according to the pressure of the stored gas in the method of the present invention shown in fig. 2, which may include: step S210 to step S240.
Step S210, when the current temperature of the air compressor is less than or equal to the set temperature threshold, obtaining the current pressure of the preset air reservoir, especially obtaining the current pressure of the recovery air reservoir, for example: the current pressure of the recovery air cylinder can be collected through a pressure sensor or a pressure switch.
Step S220, determining whether the current pressure of the preset air cylinder is greater than a set pressure threshold.
Step S230, if the current pressure of the preset gas cylinder is greater than the set pressure threshold, controlling the gas exhaust pipe of the preset gas cylinder to open, so as to deliver the stored gas stored in the preset gas cylinder to the air compressor, thereby avoiding the potential safety hazard caused by the excessive pressure of the stored gas stored in the preset gas cylinder. For example: the method comprises the steps of recovering exhaust energy of an entire pneumatic system of the vehicle, using an air storage cylinder to store the gas energy, detecting the pressure of the gas energy through a pressure sensor (or a pressure switch), using an ECU (electronic control Unit) to control, discharging the part of the gas energy when the pressure of the gas energy reaches a certain range, and cooling an air compressor.
Step S240, if the current pressure of the preset gas cylinder is less than or equal to the set pressure threshold, controlling the exhaust pipe of the preset gas cylinder to be turned off, so as to control the stored gas stored in the preset gas cylinder, and continuously increasing the storage capacity for storage or continuously maintaining the storage capacity for storage, without temporarily delivering the stored gas to the air compressor. For example: an exhaust valve, such as an exhaust solenoid valve, is arranged in the exhaust pipeline of the preset air cylinder and can control the exhaust valve in the exhaust pipeline of the preset air cylinder to be closed.
For example: at TCOMIn the event that the conducting condition of the exhaust 2/2 solenoid valve is not met, i.e. at TCOMNot more than preset temperature value TSETIn the case of (1), in the process of gradually increasing the pressure in the air cylinder, the pressure sensor detects the pressure in the air cylinder and transmits a pressure signal to the exhaust control ECU. The ECU receives the pressure signal of the pressure sensor and controls the on-off of the exhaust 2/2 electromagnetic valve to control the air storage of the air storage cylinderOr to the outside (atmosphere). According to different vehicle types and different pneumatic systems, the exhaust control ECU sets a pressure value PSET. Collecting pressure or pressure P of low-pressure gas cylinderLWhen detecting the pressure P of the gas cylinderL＞PSETWhen the preset value is reached, the ECU controls the electromagnetic valve for conducting exhaust 2/2 to exhaust. Otherwise, the electromagnetic valve of the exhaust 2/2 is controlled to be closed, and the air storage of the air storage cylinder is carried out.
For another example: the pressure intensity in the air storage cylinder can be detected by adopting a pressure switch. According to different models and different pneumatic systems, the pressure switch with the proper pressure value is selected by the low-pressure air cylinder. When the pressure switch detects that the pressure is too high, the pressure switch transmits a pressure over-high signal to the exhaust control ECU, and the ECU controls to conduct the electromagnetic valve of the exhaust 2/2 to perform exhaust. Otherwise, the electromagnetic valve of the exhaust 2/2 is controlled to be closed, and the air storage of the air storage cylinder is carried out.
Therefore, the reliability and the safety of the storage of the stored gas can be ensured by carrying out the conveying control according to the pressure of the stored gas under the condition that the current temperature of the air compressor is less than or equal to the set temperature threshold; and the air compressor can be flexibly cooled, and the energy is saved and the safety is realized.
In an alternative embodiment, the method may further include: a process for recovering exhaust gas from a starting system of an automobile.
Specifically, the recovery air cylinder can be arranged in an exhaust pipeline of a pneumatic system of the automobile, the recovery pipeline of the recovery air cylinder is controlled to be opened under the condition that the pneumatic system of the automobile exhausts, the exhaust gas of the pneumatic system of the automobile is recovered and stored, namely the exhaust gas exhausted by the pneumatic system of the automobile is recovered and stored, so that the exhaust gas recovered and stored by the recovery air cylinder is used for cooling the air compressor. For example: a recovery valve, such as a recovery solenoid valve, is arranged in the recovery pipeline of the recovery air cylinder and can control the recovery valve in the recovery pipeline of the recovery air cylinder to be opened.
Wherein, the recovery pipeline of the recovery air cylinder is a one-way conduction pipeline. That is, when the recovery pipe of the recovery gas cylinder is opened, the gas discharged from the gas cylinder system can be recovered only in one direction, and the recovered gas cannot flow in the reverse direction to the pneumatic system.
For example: an exhaust gas path and an air storage cylinder can be additionally arranged at each exhaust part of the pneumatic system to collect exhaust gas of the pneumatic system; and the ECU detects data of the pressure sensor and the temperature sensor, controls the gas discharge of the gas storage cylinder and cools the air compressor. The air compressor is cooled by utilizing the recovered exhaust energy of the pneumatic system, so that the energy-saving effect is achieved, the heat dissipation effect of the air compressor can be improved, the temperature of the air compressor is reduced, and the reliable operation of the air compressor is guaranteed.
Therefore, the exhaust gas of the starting system of the automobile is recovered, so that the exhaust gas can be utilized, and the energy is saved.
Through a large amount of tests verification, adopt the technical scheme of this embodiment, through using low pressure gas receiver and exhaust gas circuit with the exhaust energy recovery of each gas circuit system on the car, adopt pressure sensor or pressure switch to detect its pressure condition to through ECU control exhaust solenoid valve, concentrate the exhaust, this gas circuit gas vent is in air compressor department, can reduce air compressor's temperature, avoids air compressor high temperature and breaks down or damage.

In an alternative example, the obtaining unit 102, such as an obtaining module in an ECU of a vehicle, may be used to obtain the current temperature of an air compressor in a pneumatic system of the vehicle. The specific functions and processes of the acquiring unit 102 are referred to in step S110.
In an alternative example, the control unit 104, such as a control module in an ECU of an automobile, may be used to determine whether the current temperature of the air compressor is greater than a set temperature threshold. The specific function and processing of the control unit 104 are referred to in step S120.
In an optional example, the control unit 104 may be further configured to deliver the stored gas to the air compressor to cool the air compressor if the current temperature of the air compressor is greater than the set temperature threshold. The stored gas is pre-stored gas with temperature in a set temperature range and/or pressure in a set pressure range. For example: the upper limit of the set temperature range may be smaller than the set temperature threshold. The specific function and processing of the control unit 104 are also referred to in step S130.
For example: through ECU control solenoid valve break-make condition, make this gas circuit system air pressure control in suitable within range to air compressor carries out the cooling treatment, can solve the air compressor machine heat dissipation not good, prevents that air compressor machine during operation casing temperature is too high, leads to the problem of air compressor machine damage. The problem of waste of exhaust energy of the gas path system can be solved.
Therefore, the stored gas is conveyed to the air compressor under the condition that the current temperature of the air compressor is greater than the set temperature threshold value, so that the stored gas is utilized to cool the air compressor to reduce the temperature of the air compressor, the air compressor is prevented from being broken down or damaged due to overhigh temperature, and the working reliability and safety of the air compressor are improved.
Alternatively, the control unit 104 may deliver the stored gas to the air compressor, and may include: the control unit 104 may be further configured to control an exhaust pipe of the preset gas cylinder to open so as to deliver the stored gas stored in the preset gas cylinder to the air compressor, so as to cool the air compressor by using the stored gas stored in the preset gas cylinder. For example: an exhaust valve, such as an exhaust solenoid valve, is arranged in the exhaust pipeline of the preset air cylinder and can control the opening of the exhaust valve in the exhaust pipeline of the preset air cylinder. The ECU detects the pressure of the air storage cylinder, the exhaust solenoid valve is opened after the preset pressure is reached, and the low-temperature gas is used for cooling the air compressor by utilizing the principles of forced convection and gas expansion heat absorption.
That is, in the case where the preset gas cylinder may include a recovery gas cylinder, delivering the storage gas to the air compressor may include: under the condition that the current temperature of the air compressor is greater than a set temperature threshold value, directly controlling an exhaust pipeline of the preset air storage cylinder to be opened so as to convey stored gas to the air compressor.
Wherein, in presetting the gas receiver, it has storage gas to store in advance to when air compressor need cool down the processing, utilize the storage gas of storing in advance in presetting the gas receiver to cool down the processing to air compressor.
For example: the exhaust energy of each air path system on the vehicle can be recovered by using the low-pressure air cylinder and the exhaust air path, the pressure condition of the low-pressure air cylinder is detected by using a pressure sensor (or a pressure switch), the exhaust electromagnetic valve of the ECU (electronic control unit) for controlling 2/2 is used for carrying out centralized exhaust, and the exhaust port of the air path is arranged at the air compressor. Exhaust control ECU real-time acquisition of air compressor temperature TCOMWhen T isCOMGreater than a preset temperature value TSETWhen the solenoid valve for exhaust 2/2 is turned on (i.e., the two-way solenoid valve for exhaust) to perform exhaust.
From this, predetermine the storage gas of storing in the gas receiver and carry to air compressor department through the control, realize the cooling of air compressor and handle, simple and convenient and reliable.
More optionally, the output port of the exhaust pipeline of the preset air storage cylinder is arranged towards the heat generating area or the set temperature area of the air compressor.
For example: the exhaust port of the pipeline system faces the highest temperature position of the air compressor, the air compressor can be cooled by utilizing the forced convection phenomenon, in addition, the exhaust gas temperature of the exhaust port of the pipeline system is lower by utilizing the principle that gas expands and absorbs heat from a high pressure side to a low pressure side, and when the exhaust port of the pipeline system exchanges heat with the air compressor, the air compressor can be further cooled.
From this, through making the delivery outlet of predetermineeing the air receiver towards air compressor's the regional or set for temperature region etc. transport storage gas that generates heat, can promote cooling efficiency to save storage gas.
Optionally, the preset air cylinder may include: a spare air reservoir and/or a recovery air reservoir. For example: the preset air cylinder can comprise: a reserve air reservoir that may be used to store a reserve gas, and/or a recovery air reservoir that may be used to store a recovery gas.
Wherein, reserve air receiver can be used for storing reserve gas in advance to the reserve gas that utilizes the storage cools down air compressor.
The recovery air cylinder can be used for recovering and storing the exhaust gas of an exhaust system of an automobile in the exhaust process of the exhaust system in a pneumatic system of the automobile so as to cool an air compressor by utilizing the recovered and stored exhaust gas.
That is, the stored gas is delivered to the air compressor, and may include a plurality of delivery processes, such as a first delivery process, a second delivery process, and the like, and particularly, refer to the following description.
Specifically, the exhaust pipe of the preset backup air reservoir may be controlled to be opened, so that the backup air stored in the backup air reservoir is delivered to the air compressor as the stored air. For example: and the standby gas stored in the standby air storage cylinder is used as the storage gas through the opened exhaust valve of the standby air storage cylinder and is conveyed to the air compressor. Wherein, reserve air receiver can be the air storage equipment that can be used for cooling down to air compressor that sets up in advance, has stored in advance in reserve air receiver and can be used for the low temperature and/or the low pressure gas that the air compressor cooled down.
Specifically, the exhaust pipe of the preset recovery gas cylinder can be controlled to be opened so as to convey the recovered gas stored in the recovery gas cylinder to the air compressor as the stored gas.
For example: when each part (such as an air suspension and the like) of a pneumatic system of an automobile exhausts, the exhausted high-pressure gas is collected, and the pressure in the low-pressure gas storage cylinder is gradually increased. The exhaust control is started and the ECU starts operating. If in the form of a pipeline, the exhaust gas of the pneumatic system of the whole vehicle is recovered and is only stored in a low-pressure air storage cylinder in a one-way mode (the pressure P of the air storage cylinder)L< pressure P of the solenoid valven) The exhaust part of the pneumatic system is subjected to optimization treatment of centralized control, the pipeline exhaust port is arranged at the air compressor, and finally the exhaust control ECU controls the exhaust time sequence to cool the air compressor.
For example: can retrieve whole car pneumatic system's exhaust through the pipeline, the storage is in the air receiver, carry out the centralized processing optimization to pneumatic system exhaust part's logic, and use ECU control air receiver outside (atmosphere) exhaust, the gas vent of this system is facing to air compressor highest temperature department, utilize forced convection phenomenon can cool down air compressor, in addition, utilize the gas from high-pressure side to the endothermic principle of low pressure side inflation, the gas temperature of gas vent exhaust of this system is lower, when carrying out the heat exchange with air compressor, can go on further cooling to air compressor. The exhaust gas of the whole vehicle pneumatic system is recovered through a pipeline and stored in an air storage cylinder. Therefore, the air displacement of the whole vehicle pneumatic system is different by using the thinking of zero storage and retrieval, the recyclable energy is different, and the air storage cylinder is used for storing air, so that the energy of each part of the pneumatic system can be concentrated and utilized.
Therefore, the stored gas is stored in various gas storage modes, so that the stored gas is more convenient and flexible to cool the air compressor.
Optionally, the control unit 104, in a case that the air compressor is cooled by using the storage gas stored in the preset gas cylinder, especially in a case that the preset gas cylinder may include a recovery gas cylinder, may further include:
the obtaining unit 102 or the control unit 104 may be further configured to obtain a current pressure of a preset air reservoir, especially obtain a current pressure of a recovery air reservoir, when a current temperature of the air compressor is less than or equal to a set temperature threshold, for example: the current pressure of the recovery air cylinder can be collected through a pressure sensor or a pressure switch. The specific functions and processes of the control unit 104 are also referred to in step S210.
The control unit 104 may be further configured to determine whether a current pressure of the preset air reservoir is greater than a set pressure threshold. The specific functions and processes of the control unit 104 are also referred to in step S220.
The control unit 104 may be further configured to control the exhaust pipe of the preset gas cylinder to open if the current pressure of the preset gas cylinder is greater than the set pressure threshold, so as to deliver the stored gas stored in the preset gas cylinder to the air compressor, thereby avoiding a potential safety hazard caused by an excessive pressure of the stored gas stored in the preset gas cylinder. The specific function and processing of the control unit 104 are also referred to in step S230. For example: the method comprises the steps of recovering exhaust energy of an entire pneumatic system of the vehicle, using an air storage cylinder to store the gas energy, detecting the pressure of the gas energy through a pressure sensor (or a pressure switch), using an ECU (electronic control Unit) to control, discharging the part of the gas energy when the pressure of the gas energy reaches a certain range, and cooling an air compressor.
The control unit 104 may be further configured to, if the current pressure of the preset gas cylinder is less than or equal to the set pressure threshold, control the exhaust pipe of the preset gas cylinder to be turned off, so as to control the stored gas stored in the preset gas cylinder, continue to increase the storage capacity for storage, or continue to maintain the storage capacity for storage, and temporarily not deliver the stored gas to the air compressor. The specific function and processing of the control unit 104 are also referred to in step S240. For example: an exhaust valve, such as an exhaust solenoid valve, is arranged in the exhaust pipeline of the preset air cylinder and can control the exhaust valve in the exhaust pipeline of the preset air cylinder to be closed.
For example: at TCOMIn the event that the conducting condition of the exhaust 2/2 solenoid valve is not met, i.e. at TCOMNot more than preset temperature value TSETIn the case of (1), in the process of gradually increasing the pressure in the air cylinder, the pressure sensor detects the pressure in the air cylinder and transmits a pressure signal to the exhaust control ECU. The ECU receives the pressure signal of the pressure sensor and controls the on-off of the exhaust 2/2 electromagnetic valve so as to control the air storage of the air storage cylinder or exhaust to the outside (atmosphere). According to different vehicle types and different pneumatic systems, the exhaust control ECU sets a pressure value PSET. Collecting pressure or pressure P of low-pressure gas cylinderLWhen detecting the pressure P of the gas cylinderL＞PSETWhen the preset value is reached, the ECU controls the electromagnetic valve for conducting exhaust 2/2 to exhaust. Otherwise, the electromagnetic valve of the exhaust 2/2 is controlled to be closed, and the air storage of the air storage cylinder is carried out.
For another example: the pressure intensity in the air storage cylinder can be detected by adopting a pressure switch. According to different models and different pneumatic systems, the pressure switch with the proper pressure value is selected by the low-pressure air cylinder. When the pressure switch detects that the pressure is too high, the pressure switch transmits a pressure over-high signal to the exhaust control ECU, and the ECU controls to conduct the electromagnetic valve of the exhaust 2/2 to perform exhaust. Otherwise, the electromagnetic valve of the exhaust 2/2 is controlled to be closed, and the air storage of the air storage cylinder is carried out.
Therefore, the reliability and the safety of the storage of the stored gas can be ensured by carrying out the conveying control according to the pressure of the stored gas under the condition that the current temperature of the air compressor is less than or equal to the set temperature threshold; and the air compressor can be flexibly cooled, and the energy is saved and the safety is realized.
In an alternative embodiment, the method may further include: a process for recovering exhaust gas from a starting system of an automobile.
The control unit 104 may further be configured to control the recovery pipe of the recovery air cylinder to open under the condition that the pneumatic system of the automobile exhausts through the recovery air cylinder disposed in the exhaust pipe of the pneumatic system of the automobile, so as to recover and store the exhaust gas of the pneumatic system of the automobile, that is, recover and store the gas exhausted from the pneumatic system of the automobile, so as to cool the air compressor by using the exhaust gas recovered and stored by the recovery air cylinder. For example: a recovery valve, such as a recovery solenoid valve, is arranged in the recovery pipeline of the recovery air cylinder and can control the recovery valve in the recovery pipeline of the recovery air cylinder to be opened.
Wherein, the recovery pipeline of the recovery air cylinder is a one-way conduction pipeline. That is, when the recovery pipe of the recovery gas cylinder is opened, the gas discharged from the gas cylinder system can be recovered only in one direction, and the recovered gas cannot flow in the reverse direction to the pneumatic system.
For example: an exhaust gas path and an air storage cylinder can be additionally arranged at each exhaust part of the pneumatic system to collect exhaust gas of the pneumatic system; and the ECU detects data of the pressure sensor and the temperature sensor, controls the gas discharge of the gas storage cylinder and cools the air compressor. The air compressor is cooled by utilizing the recovered exhaust energy of the pneumatic system, so that the energy-saving effect is achieved, the heat dissipation effect of the air compressor can be improved, the temperature of the air compressor is reduced, and the reliable operation of the air compressor is guaranteed.
Therefore, the exhaust gas of the starting system of the automobile is recovered, so that the exhaust gas can be utilized, and the energy is saved.
