Technical field
The present invention relates to technical field of vehicle manufacture, more specifically to a kind of vehicle and its engine.
Background technology
In engine working process, inevitably there is gas leak phenomenon in its piston ring, cause unburned mixture body to enter
In crankcase.Therefore, gas exhaust piping is must be provided with the part communicated on the crankcase of engine or with crankcase, so that
Unburned mixture body in crankcase reenters gas in-cylinder combustion, and otherwise crankcase air pressure inside is excessive has potential safety hazard.
Unburned mixed gas is passed through during crankcase, inevitably with the tiny machine oil droplets mixing in crankcase, therefore warp
Cross crankcase unburned mixed gas reenter needed before gas in-cylinder combustion carry out Oil-gas Separation so that unburned gaseous mixture
Body is separated with machine oil, and then is avoided engine motor oil excessive oil consumption and improved the economy and reliability of vehicle.
As shown in figure 1, the oil-gas separation mechanism of crankcase is generally gas in static labyrinth type, crankcase in the prior art
From right side enter, by labyrinth type oil-gas Disengagement zone 02, final machine oil flows down into from left side and leads to oil sump, gas then to
Upper movement enters air filter through breather pipe 01.But the separating effect of said structure is unsatisfactory, and labyrinth type Disengagement zone needs
Take the much room of crankcase.
In summary, how to effectively improve oil gas separation and save installing space, be current people in the art
Member's urgent problem.
