Steam condensation is thinning, performance decline, and combustion mixture and exhaust gas enter in crankcase and can also crankcase pressure be increased
Greatly, machine oil increases the pollution in engine operation process to atmosphere, therefore, it is necessary to pass through from crankshaft oil seal, liner etc. leakage
It integrates gs-oil separator in valve mechanism cover to separate come the oil gas for excluding engine, traditional valve mechanism cover can only carry out
Single separation, effect can not reach expected.
Such as a kind of Chinese utility model patent " valve mechanism cover " of Publication No. CN205559013U, including valve mechanism cover sheet
Body, cylinder head cover body inside are formed with oil gas pre-separation chamber, and the oil gas pre-separation chamber is equipped with pre-separation air inlet and in advance
Gas outlet is separated, is successively arranged from the pre-separation air inlet to the pre-separation gas outlet along vertical in oil gas pre-separation room
The spaced multiple lateral partitions in direction and in the horizontal direction be in the spaced multiple longitudinal baffles of labyrinth type, lateral partitions
The mazy gas channel for being connected to pre-separation air inlet and pre-separation gas outlet is formed between longitudinal baffle, and in cylinder head
Cover lateral wall is integrated with gs-oil separator.
Such as the Chinese invention patent " active gs-oil separator " of Publication No. CN104265402B, pass through extreme pressure lubricant
Driving is a kind of oily drive formula active separator, can carry out active separation to the gas mixture in crankcase, but only with master
Dynamic formula separator separative efficiency is lower, is unable to satisfy six discharge standard of state.
By the above content it can be found that in the prior art the core of valve mechanism cover oil gas pre-separation be lateral partitions with
The mazy gas channel formed between longitudinal baffle, but its single layer structure Oil-gas Separation ability is poor, low separation efficiency.
