Background
With the stricter emission regulations of passenger cars, the engine of the passenger cars mostly adopts a closed forced crankshaft ventilation system, and mixed gas obtained after oil vapor in a crankcase is subjected to oil-gas separation is introduced into an air inlet manifold again and returns to a combustion chamber for secondary combustion, so that the pollutant emission of the crankcase can be reduced, and the economical efficiency of the engine can be improved. The system is therefore widely used.
Because the high pressure in the cylinder and the air leakage of the piston are caused when the engine works, the higher the engine load is, the higher the fuel oil and water vapor content of the crankcase is. In northeast and northwest areas of China, the environment temperature is usually below-30 ℃ in winter, hot mixed steam from a crankcase enters an air inlet hose through a curved pipe, and when extremely cold air is met at the junction of the curved pipe and the air inlet hose, water vapor containing fuel steam is instantly condensed to freeze the junction. Over time, there is a greater accumulation of ice, which eventually becomes clogged. The mixed gas of the crankcase can not be discharged, the pressure rises, and the sealing system of the crankcase fails and oil leakage is caused. The pressure of the crankcase is too high, the oil return of the supercharger is abnormal, the supercharger is damaged for a long time, and irreversible damage is caused to the engine.
The conventional automobile without electric heating is easy to freeze a crankshaft pipe in winter, so that the whole automobile is anchored; the traditional crank heating system starts heating without controlling the whole vehicle to be electrified, so that the waste of electric energy is caused.
