Description

Cooling system for effectively solving engine oil dilution phenomenon

Technical Field

The utility model belongs to the technical field of the car, specific cooling system who effectively solves engine oil dilution phenomenon that says so.

Background

The direct injection small-displacement engine in the turbocharging cylinder is used at low speed and short mileage for a long time in a low-temperature environment in winter, the temperature of the engine can not be continuously increased, and the risk of engine oil dilution exists.

The temperature of the inner wall surface of the cylinder body is low, fuel oil is directly sprayed and then attached to the inner wall of the cylinder, and attached gasoline flows into a crankcase through an oil return hole of the oil ring in a compression stroke, so that the gasoline is mixed into engine oil. The temperature of the engine oil in the oil bottom case is low in the warming-up process, and the gasoline mixed in the engine oil cannot volatilize in time, so that the engine oil is diluted.

Disclosure of Invention

The utility model provides a simple structure's cooling system who effectively solves engine machine oil dilution phenomenon connects gearbox machine oil cooling circuit and engine macrocycle cooling circuit in parallel, receives cylinder cap thermostat control simultaneously for gearbox oil cooler does not participate in the circulation at engine intensification in-process, prevents oil cooler heat absorption, thereby accelerates engine intensification process, through the test, can effectively shorten engine warm-up time, thereby solves engine machine oil dilution problem.

The technical scheme of the utility model is explained as follows with the attached drawings:

a cooling system for effectively solving the engine oil dilution phenomenon of an engine comprises an engine large circulation cooling loop, a gearbox engine oil cooling loop, an engine oil cooling and air conditioning warm air loop and an engine turbocharger cooling loop; the engine large circulation cooling loop is formed by starting from the engine 1, passing through the thermostat 2, the radiator 3 and the mechanical water pump 4 and then returning to the engine 1; the gearbox oil cooling loop starts from the engine 1, and returns to the engine 1 after passing through the thermostat 2, the gearbox oil cooler 5 and the mechanical water pump 4; the engine oil cooling and air conditioning warm air loop starts from the engine 1, passes through the warm air 6 and the engine oil cooler 7 and then returns to the engine 1 to form the engine oil cooling and air conditioning warm air loop; the engine turbocharger cooling loop is formed by starting from the engine 1, passing through the electric water pump 8, the turbocharger 9, the liquid storage tank 10 and the mechanical water pump 4 and then returning to the engine 1.
