Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present 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.
The invention discloses a heating method of a non-electric control engine, which can strictly control the heating process of the engine and reduce the deviation of heating time, thereby improving the performance of the non-electric control engine.
Referring to fig. 1, fig. 1 is a flow chart illustrating a heating method of a non-electric control engine according to the present disclosure. The method comprises the following steps:
step S1: and starting a heating device to heat the non-electric control engine.
In a motor vehicle, a heating device for heating a non-electric controlled engine is provided, and the heating device is provided with an independent operation switch.
Step S2: and detecting the ambient temperature of the non-electric control engine at the current moment as a first ambient temperature.
The ambient temperature of the non-electronically controlled engine at the present time is detected by a temperature sensor, and for the sake of simplicity of the description, it is referred to as a first ambient temperature. It should be noted that the ambient temperature of the non-electrically controlled engine may be the temperature of the air in the space outside the non-electrically controlled engine, or may be the temperature of the cooling water in the cooling water tank of the motor vehicle.
Step S3: and determining the intake air preheating time corresponding to the first ambient temperature by utilizing the corresponding relation between the preset ambient temperature and the intake air preheating time.
Before the non-electric control engine is started, preheating treatment needs to be carried out on the non-electric control engine, if the preheating time is too short, the fuel oil atomization effect and the mixing effect are poor due to the fact that the air inlet temperature is low after the non-electric control engine is started, HC is easily formed at the moment, smoke of the non-electric control engine is large, the smoke exhaust duration is long, meanwhile, the ignition delay period is prolonged due to the fact that the air inlet temperature is low, and diffusion combustion is not facilitated. If the preheating time is too long, the service life of the non-electric control engine can be influenced. The applicant of the invention carries out a plurality of tests aiming at a plurality of different environment temperatures, determines the optimal air inlet preheating time corresponding to the plurality of environment temperatures, then forms the corresponding relation between the environment temperature and the air inlet preheating time through data processing, and stores the corresponding relation.
When the temperature sensor detects the ambient temperature of the non-electric control engine, the intake air preheating time corresponding to the ambient temperature can be determined through the corresponding relation.
Step S4: and outputting first prompt information when the duration of the heating treatment reaches the air inlet preheating time.
When a driver starts the heating device, the heating device is timed, namely, the running time of the heating device is timed, and when the duration time of the heating device reaches the air inlet preheating time, first prompt information is output to remind the driver that the preheating time is reached. After receiving the first prompt message, the driver can start the non-electric control engine.
In an implementation, the first prompt message may be a light prompt message. For example: after the heating device is started, the indicator lamp is turned on, and when the duration time of the heating treatment reaches the air inlet preheating time, the indicator lamp is turned off; or after the heating device is started, the indicator lamp is in an off state, and the indicator lamp is turned on after the heating treatment duration time reaches the air inlet preheating time. Of course, the first prompt message may also be a voice prompt message, and a corresponding prompt voice is sent out after the duration of the heating treatment reaches the intake air preheating time. Of course, the first prompt message may also be a combination of a light prompt message and a voice prompt message. The present invention is not limited thereto.
In the heating method of the non-electric control motor disclosed by the invention, the environmental temperature of the non-electric control motor is detected firstly, then the heating time is determined by utilizing the corresponding relation between the preset environmental temperature and the intake preheating time, and the heating time is not determined by the experience of a driver any more, so that the deviation caused by different manual experiences is avoided, the accurate control of the heating process is realized, in addition, the corresponding relation reflects the better intake preheating time corresponding to each environmental temperature, the intake preheating time determined according to the corresponding relation cannot be overlong or overlong, and the performance of the non-electric control motor can be improved.
After the non-electric control engine is preheated, the driver can rotate the key switch to start the non-electric control engine. However, if the ambient temperature is too low (e.g. cold weather), the non-electric controlled engine still has the problems of poor fuel atomization and mixing effects, long smoke discharge duration and prolonged ignition delay period due to low intake temperature. Therefore, the invention discloses another heating method of the non-electric control engine, which aims to solve the problem that the non-electric control engine can be heated in severe cold conditions.
Referring to fig. 2, fig. 2 is a flow chart illustrating another method for heating a non-electronically controlled engine disclosed herein. The method comprises the following steps:
step S1: and starting a heating device to heat the non-electric control engine.
Step S2: and detecting the ambient temperature of the non-electric control engine at the current moment as a first ambient temperature.
Step S3: and determining the intake air preheating time corresponding to the first ambient temperature by utilizing the corresponding relation between the preset ambient temperature and the intake air preheating time.
Step S4: and outputting first prompt information after the heating treatment lasts for the air inlet preheating time.
Step S5: and after the non-electric control engine is successfully started, detecting the ambient temperature of the non-electric control engine at the current moment as a second ambient temperature.
Whether the non-electric control motor is started successfully or not can be judged by detecting the rotating speed of the non-electric control motor. Specifically, the rotation speed of the engine is 0 in a non-start state of the engine, and reaches an idle rotation speed in a successful start state of the engine. In implementation, a rotating speed sensor can be arranged on a flywheel casing of the non-electric control engine to detect the rotating speed of the non-electric control engine. The second ambient temperature in step S5 may be the temperature of the air in the space outside the electronically non-controlled engine or the temperature of the cooling water in the cooling water tank of the motor vehicle.
Step S6: it is determined whether the second ambient temperature is lower than the threshold temperature, and if the second ambient temperature is lower than the threshold temperature, step S7 is executed.
Step S7: and determining the post-air-intake hot time corresponding to the second ambient temperature by utilizing the corresponding relation between the preset ambient temperature and the post-air-intake hot time.
After the non-electric control engine is preheated and started successfully, if the ambient temperature of the non-electric control engine is still lower than the threshold temperature, the non-electric control engine needs to be subjected to air intake post-heat treatment. The applicant of the invention determines the corresponding relation between the ambient temperature and the intake post-heating time through a plurality of tests, and when the ambient temperature of the non-electric control engine detected by the temperature sensor at the current moment is lower than the threshold temperature, the intake post-heating time corresponding to the ambient temperature can be determined by utilizing the corresponding relation.
Step S8: and outputting second prompt information when the duration of the heating treatment after the non-electric control engine is successfully started reaches the post-air-intake hot time.
And after the non-electric control engine is successfully started, timing the heating treatment process again. That is, the running time of the heating device after the non-electronically controlled engine is successfully started is counted. And when the duration time of the heating treatment after the non-electric control engine is successfully started reaches the determined air intake post-heat time, outputting second prompt information to remind a driver that the air intake post-heat treatment process is finished. The driver may turn off the heating device after receiving the second prompt message.
In practice, the second prompting message may be a light prompting message, a voice prompting message, or a combination thereof. Of course, the first prompt message and the second prompt message are output in different forms so as to be distinguished by the driver.
According to the heating method of the non-electric control engine disclosed by the invention, the environment temperature of the non-electric control engine is further detected after the non-electric control engine is successfully started, and when the environment temperature is lower than the threshold temperature, the non-electric control engine is subjected to air inlet post-heat treatment, so that the problems of poor fuel atomization effect and mixing effect, long smoke discharge duration and prolonged ignition delay period in severe cold weather are solved.
Preferably, when it is determined in step S6 that the second ambient temperature is not lower than the threshold temperature, a step of outputting a third prompt message may be further included. The third prompt message is used for indicating that the non-electric control engine does not need to carry out air inlet post-heat treatment, and the driver can immediately turn off the heating device after receiving the third prompt message.
Of course, the third prompt message may be a light prompt message, a voice prompt message, or a combination thereof. Of course, the first prompt message, the second prompt message and the third prompt message are output in different forms so as to be distinguished by the driver.

When the timing value of the first timer 4 reaches the air intake preheating time of the first arithmetic unit 3, the first processing unit 5 outputs a first prompt message to remind the driver that the preheating time is reached. After receiving the first prompt message, the driver can start the non-electric control engine.
It should be noted that the first prompt message may be a light prompt message. For example: after the heating device is started, the indicator lamp is turned on, and when the duration time of the heating treatment reaches the air inlet preheating time, the indicator lamp is turned off; or after the heating device is started, the indicator lamp is in an off state, and the indicator lamp is turned on after the heating treatment duration time reaches the air inlet preheating time.
