Abstract

The present disclosure provides a crankcase ventilation mechanism and an engine. The crankcase ventilation mechanism includes: a valve chamber cover having a first inner chamber and a second inner chamber isolated from each other, and a first inlet for communicating with the crankcase. An air port and a second air inlet for communicating with the crankcase, the first air inlet communicates with the first inner chamber, and the second air inlet communicates with the second inner chamber; the cylinder head , which is connected to the valve chamber cover, has an intake air passage and an air delivery passage, one end of the intake air passage communicates with the first inner cavity, and the other end of the intake air passage is used for intake air with the cylinder head One end of the air delivery channel communicates with the second inner cavity, and the other end of the air delivery channel communicates with the supercharger. The present disclosure can save a large amount of space occupied by peripheral pipelines in the crankcase ventilation mechanism, realize lightweight design, and facilitate and quickly complete assembly.

Description

technical field [0001] The present disclosure relates to the technical field of automobile engines, in particular to a crankcase ventilation mechanism and an engine. Background technique [0002] When the engine is working, the combustible mixture in the combustion chamber and the exhaust gas after combustion can enter the crankcase through the gap between the piston and the cylinder wall and the gap between the piston ring openings. In addition, when the supercharger is working, some blow-by air will escape from the supercharger intermediate body to the crankcase. Therefore, a crankcase ventilation mechanism is usually provided to discharge the exhaust gas in the crankcase from the crankcase in time to prevent the pressure of the crankcase from rising and avoid oil leakage and engine damage. [0003] In the related art, the crankcase ventilation mechanism usually returns the exhaust gas to the engine for re-combustion, so as to reduce air pollution and protect the environm...
