Background

The oil pan is positioned at the lower part of the engine and is used for sealing the crankcase to be used as a shell of an oil storage tank, preventing impurities from entering, collecting and storing lubricating oil flowing back from each friction surface of the diesel engine and preventing the lubricating oil from being oxidized. In cold areas in winter, due to low air temperature, the comprehensive performance of engine lubricating oil is reduced, gaps among parts are large, a large amount of mechanical loss is caused when a vehicle is in cold start, parts are seriously abraded, scrap iron is easily generated, and the damage of the vehicle is accelerated.

After the engine stops operating, the lubricating oil flows to the bottom of the oil pan, and the viscosity is high and the fluidity is poor at low temperature, so that the parts cannot be lubricated well. Typically, the vehicle owner will perform an idle hot vehicle in place prior to driving; or low-temperature high-fluidity lubricating oil is adopted to reduce the friction of the engine during cold start.

The scheme has the defects that the preheating time of the vehicle engine is long, the heating speed is slow, and the waste of oil is caused; the low-temperature high-fluidity lubricating oil is higher in price, and the use cost is increased.

The heating wire 8 is tightly attached to the lower end of the shell of the oil pan 7, and the temperature sensor 6 is clamped on the side wall of the shell of the oil pan 7 and extends into oil liquid contained in the shell.

The decision-making executing mechanism comprises a first executing switch 41, a second executing switch 42 and a third executing switch 43. The three are in different open-close states under different conditions so as to control different power supplies to supply power to the system.

When the vehicle is powered on but the engine is not started, the temperature sensor 6 transmits the detected engine oil temperature to the ECU5, if the engine oil temperature is too low, the ECU5 decides to turn on the first execution switch 41, at the moment, the vehicle battery 1 supplies power to the system, and the heating wire 8 starts to work; if the engine oil temperature reaches the calibration value, the ECU5 decides to open the third execution switch 43, the third execution switch 43 is connected with the breaker 3, the system is broken, and the heating wire 8 stops working.

When the vehicle is powered on and the engine is started, the temperature sensor 6 transmits the detected engine oil temperature to the ECU5, if the engine oil temperature is too low, the ECU5 decides to turn on the second execution switch 42, at the moment, the vehicle generator 2 supplies power to the system, and the heating wire 8 starts to work; if the engine oil temperature reaches the calibration value, the ECU5 decides to open the third execution switch 43, the third execution switch 43 is connected with the breaker 3, the system is broken, and the heating wire 8 stops working.

When the vehicle is shut down and the engine stops working, the ECU5 decides to turn on the third execution switch 43, the system is disconnected, and the heating wire 8 stops working. The ECU5 and the temperature sensor 6 are independently powered by the vehicle body circuit and are not influenced by the power failure of the system.

As shown in figure 2, the heating wire 8 adopts a spiral winding mode, and the winding mode can generate a magnetic field after being electrified, so that the shell of the oil pan 7 is slightly magnetized, and tiny scrap iron is adsorbed into the impurity collecting groove 9.
