[0026] like Figure 1 The present invention provides a technical solution: an engine auxiliary starting control method suitable for low temperature environment conditions:

[0027] After the engine has determined its landing location, the engine auxiliary starting control system is powered on for the first time, and the latitude and longitude information of the equipment and the current altitude are obtained through the GPS positioning system. The current regional environmental information is obtained through positioning and current time. The obtained environmental information is compared with the environmental information recorded inside the equipment at the time of the last shutdown to determine the current working environment of the engine. Based on the comparison results and the changed geographic information, the engine auxiliary equipment is started through the GPS positioning system to preheat the equipment in advance, so that the engine is in a standby state and is ready to work at any time.

[0028] The engine control system obtains the current engine status through the engine ECU and environmental detection sensors, including but not limited to ambient temperature, atmospheric pressure, high-temperature cooling water temperature, low-temperature cooling water temperature and oil temperature;

[0029] If the engine cooling water temperature is lower than the preset value, the cooling water preheating unit is controlled to start working to preheat the engine cooling water temperature;

[0030] If the engine oil temperature is lower than the preset value, the oil preheating unit is controlled to start working to preheat the engine oil temperature;

[0031] If the engine oil temperature is lower than the preset value, the oil preheating unit is controlled to start working to preheat the engine oil temperature;

[0032] If the ambient temperature is lower than the preset value, a preheating control signal is sent to the intake air heating device to put the engine into preheating working state;

[0033] If the ambient temperature is lower than the preset value, the engine ECU calibration parameters will be automatically corrected, including but not limited to the engine starting fuel injection amount, engine main injection timing and other parameters.

[0034] An engine auxiliary starting device suitable for low-temperature environmental conditions, comprising an environmental detection sensor, an engine auxiliary starting controller, a battery, an engine ECU, a GPS positioning system, a GPRS data communication module, a cooling water preheating unit, an engine oil preheating unit, and an intake air heating device;

[0035] Environmental detection sensors are used to detect current environmental information;

[0036] The engine auxiliary starting controller is connected to the engine ECU via a communication bus;

[0037] The GPRS data communication module is integrated into the engine auxiliary starting control or connected to the engine auxiliary controller through a communication bus. The current equipment operation strategy is fed back to the cloud through the GPRS module, and the current equipment operation strategy can also be modified through the cloud;

[0038] The GPS positioning system is integrated into the engine auxiliary starting control or connected to the engine auxiliary controller through a communication bus;

[0039] The output end of the engine auxiliary starting controller is electrically connected to the input ends of the cooling water preheating unit, the oil preheating unit and the intake air heating device respectively;

[0040] The battery is used to power the above devices.

[0041] like Figure 2 The intake air heating device includes an intake air heating controller, a solenoid valve and an intake air heating and combustion unit. The intake air heating and combustion unit and the solenoid valve are configured according to the actual needs of the engine. Multiple intake air heating and combustion units and solenoid valves can be set on one engine according to working needs.

[0042] The intake air heating and combustion unit includes a blower, an atomizer, and a glow plug. The output end of the intake air heating controller is electrically connected to the input end of the solenoid valve, the glow plug, and the blower respectively. The output end of the solenoid valve is electrically connected to the input end of the atomizer. The blower is arranged toward the atomizer, and the output end of the atomizer is arranged inside the glow plug.

[0043] The intake air heating method is as follows: after receiving the intake air preheating instruction, the intake air heating controller controls the glow plug to preheat. When the glow plug is heated to the specified temperature, the intake air heating device can be put into operation.

[0044] The intake air heating controller determines the current engine operating state through the engine speed. When it determines that the engine has switched from the stop mode to the start mode, it controls the intake air heating device to start working.

[0045] When the intake air heating device is in operation, the solenoid valve can control the combustion medium such as diesel, methanol, ethanol and other liquid or gas fuels to be atomized by the atomizer and then sprayed into the glow plug according to the instructions of the intake air heating controller. After passing through the glow plug, the combustion medium is ignited to form a flame to heat the engine intake air;

[0046] When the intake air heating device is put into operation, the fan is turned on simultaneously, and the fan injects air into the intake air heating and combustion unit to supplement the engine intake air.

[0047] The intake air heating controller determines whether the engine starts normally based on the engine speed. If the engine starts successfully, the glow plug, solenoid valve and fan are turned off; if the engine does not start successfully, the fan and solenoid valve are turned off, and the glow plug is kept in working condition to prepare for the next engine start.
