Description

Engine starting system and vehicle

Technical Field

The application relates to the technical field of engines, in particular to an engine starting system and a vehicle.

Background

Engine cold start (cold-start) refers to the engine starting up after a period of time has elapsed since the last shutdown, with its internal temperature consistent with ambient temperature. Corresponding to the engine start-up, the engine is started up after the last shutdown time and under the condition that the internal temperature is higher.

The cold start of the engine is difficult to start with specific heat, especially when the ambient temperature is very low and the fuel is diesel, because the internal temperature of the engine is too low during cold start and the fuel is not easy to vaporize. In addition, the lubricating oil inside the engine may be in a solidified or precipitated state at the time of cold start, resulting in poor lubrication of individual parts.

Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following description will be made with reference to the accompanying drawings by way of specific embodiments.

Fig. 1 is a schematic structural diagram of an engine starting system according to an embodiment of the present application. As shown in fig. 1, the engine starting system includes: a control module, an engine 2 and a radiator; the radiator comprises a radiator tank 11 and a heating device;

the heating device is arranged in the radiator water tank 11, and a power end is used for being connected with an external power supply and is used for being started when the temperature of the cooling liquid in the radiator water tank 11 is monitored to be smaller than a first preset temperature threshold value;

the control module is used for controlling the engine 2 to start when the temperature of the cooling liquid is monitored to be greater than or equal to the first preset temperature threshold value.

In this embodiment, the control module may be a driving computer (ECU, electronic Control Unit) or an engine controller (Engine Management System, EMS). When receiving an engine starting instruction, the control module directly controls the engine 2 to start if the temperature of the cooling liquid of the radiator tank 11 is monitored to be greater than or equal to a first preset temperature threshold value, otherwise, the engine 2 is not started temporarily.

A heating device is arranged in the radiator tank 11, and when the temperature of the cooling liquid in the radiator tank 11 is lower than a first preset temperature threshold value, the heating device starts to heat the cooling liquid. After the heating device is started, the control module prohibits the execution of the program of controlling the engine 2 to start when the temperature of the cooling liquid is detected to be greater than the first preset temperature threshold value, but starts the engine 2 when the heating device heats the cooling liquid to the second preset temperature threshold value. Wherein the second preset temperature threshold is greater than the first preset temperature threshold.

In this embodiment, in the low-temperature environment, the operation of the vehicle-mounted storage battery is affected by low temperature, so that the heating device of this embodiment adopts an external power supply to supply power, and the engine 2 can be started under the low-temperature environment.

Specifically, the external power supply is a 220V ac power supply.

In this embodiment, the temperature control switch is a normally open switch, and when the temperature of the cooling liquid is less than a first preset temperature threshold, the temperature control switch is closed, and the heating device is electrically started.

The first preset temperature threshold may be, for example, 0 ℃.

In this embodiment, the temperature control switch is turned off when the temperature of the cooling liquid reaches the second preset temperature threshold, and the heating device is powered off to stop heating.

The second preset temperature threshold may be, for example, 100 ℃.

In one possible embodiment, as shown in fig. 1, the engine starting system further comprises a thermostat 3;

the control module is further configured to control the thermostat 3 to open a large cycle when the coolant temperature reaches the second preset temperature threshold, and start the engine 2 after the thermostat 3 is opened.

In the present embodiment, the thermostat 3 is a valve for controlling a flow path of the cooling liquid, and is a thermostat that generally includes a temperature sensing member for opening and closing a flow of air, gas or liquid by expanding or contracting.

Specifically, after the heating device heats the cooling liquid to the second preset temperature threshold, the thermostat 3 can start the large circulation to flow the high-temperature cooling liquid in the water tank into the engine 2, and when the cooling liquid reaches the proper temperature, the engine 2 is controlled to start, so that the cold start is converted into the hot start. Therefore, the problems of high emission, increased abrasion, slow warm-up and the like caused by cold start of the engine 2 can be avoided, and the damage to the engine 2 caused by the too high temperature of the cooling liquid can be avoided.

In the present embodiment, the control module may control the engine 2 to start after controlling the thermostat 3 to start for a first preset period of time.

In one possible embodiment, the radiator further comprises a radiator body 12, a radiator inlet pipe 13 and a radiator outlet pipe 14;

one end of the radiator body 12 is communicated with the engine 2 through the radiator outlet pipe 14, the other end of the radiator body 12 is communicated with the radiator tank 11, and the radiator tank 11 is communicated with the thermostat 3 through the radiator inlet pipe 13.

In this embodiment, the radiator body 12 may include a plurality of coolant passages connected between the radiator tank 11 and the radiator outlet pipe 14 to allow the coolant to rapidly dissipate heat.

In one possible embodiment, the engine starting system further comprises an engine water pump 4;

the engine water pump is connected in series in the radiator and the coolant circuit of the engine 2.

In this embodiment, the engine 2, the engine water pump 4, the radiator outlet pipe 14, the radiator inlet pipe 13, the thermostat 3, and the engine 2 may be sequentially connected to form a coolant loop.

In one possible implementation, the present embodiment provides a vehicle that includes an engine starting system as described above.

By adopting the scheme, the emission, the oil consumption and the rapid warming-up can be effectively reduced, so that the service life of the engine is prolonged.
