Abstract

The invention relates to an engine breathing system and an engine mechanism. The engine breathing system includes a cylinder head structure and a cylinder head shield arranged on the cylinder head structure; the cylinder head structure includes a cylinder head body, and the two sides of the cylinder head body are respectively provided with an oil-gas separation inlet on the intake side and an oil-gas separation inlet on the exhaust side. The inlet is separated; the cylinder head shield includes a shield body with a cover set on the cylinder head body, and a mutually independent oil-gas separation chamber on the intake side and an oil-gas separation chamber on the exhaust side are formed around the shield body and the cylinder head body; The shield body is also provided with an exhaust-side air outlet that communicates with the exhaust-side oil-gas separation chamber; an intake-side breathing channel that communicates with the intake-side oil-gas separation chamber is formed between the cylinder head body and the shield body; The side oil-gas separation chamber is provided with intake side oil-gas separation filter structure and crankcase forced ventilation valve; the exhaust side oil-gas separation chamber is provided with exhaust side oil-gas separation filter structure. The invention can simplify pipeline layout, prevent pipeline damage and reduce cost.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine breathing system and an engine mechanism. Background technique [0002] When the engine is working, some gas will escape to the crankcase. If the exhaust gas flowing into the crankcase is not discharged in time, high pressure will be formed in the crankcase, causing the seal to leak oil, and the oil will seep from the crankshaft oil seal, crankcase gasket, etc.; at the same time, the blow-by gas will also hinder the downward movement of the piston. The power of the engine will decrease with the increase of blow-by gas, and the fuel consumption rate will increase with the increase of blow-by gas. In order not to affect the normal operation of the engine, it is necessary to discharge the gas in the engine in time. Because the gas that escapes into the crankcase contains HC and other pollutants, it is not allowed to discharge these gases into the atmosphere. Therefore, ...
