Efficient clean temperature-controlled gasoline engine oil separation system

Abstract

The invention discloses an efficient clean temperature-controlled gasoline engine oil separation system. The system involves a cylinder head cover cap, a cylinder head, an intake manifold, an air filter and an ECU, wherein the cylinder head cover cap comprises a temperature sensor, an oil-gas separator, a first one-way valve, a second one-way valve, a cooler and a PCV valve; the oil-gas separatoris connected with the temperature sensor, the first one-way valve and the second one-way valve correspondingly, the first one-way valve is connected with the cooler, the second one-way valve is connected with the PCV valve, and the temperature sensor, the first one-way valve and the second one-way valve achieve signal transmission with the ECU; and the PCV valve is connected with the air filter and the intake manifold correspondingly, the air filter is connected with the intake manifold, and the other end of the intake manifold is connected with the cylinder head. According to the efficient clean temperature-controlled gasoline engine oil separation system, the problem that engine oil is "carried" out of the cylinder head cover cap is well solved, and the situation that the engine oil enters a combustion chamber along with filtered fuel gas to be combusted, so that emission is deteriorated is avoided; and meanwhile, the engine oil is recycled into an engine through primary engine oil separation and primary engine oil condensation, the engine oil consumption speed of the whole engine is reduced, and the targets of energy conservation and emission reduction are achieved.

Description

【Technical field】 [0001] The invention relates to an efficient and clean temperature-controlled gasoline engine oil separation system, in particular to the technical field of engines and vehicles. 【Background technique】 [0002] With the development of engines and the enhancement of people's awareness of environmental protection, energy saving and emission reduction are the goals pursued by our engine and vehicle designers. "Burning engine oil" has always been the "pain point" of gasoline engine particle emissions. Under certain working conditions of the engine, the oil vapor cannot be completely condensed due to the high temperature of the "blow-by gas". The gas enters the combustion chamber for combustion, which worsens the emission and achieves the goal of emission reduction. At the same time, it is worth mentioning that this condenser uses the cooling water circulated inside the engine to realize the effective use of energy and achieve the purpose of energy saving.
