Engine liquid-gas separation device, engine and automobile

Abstract

The invention discloses an engine liquid-gas separation device, an engine and an automobile. The engine liquid-gas separation device comprises a separation chamber mounting plate, a spiral channel, an outlet baffle, an outlet opening and an outlet container. In the scheme provided by the invention, a liquid and gas mixture is separated through the combined design of the mounting plate, the spiral channel, the outlet baffle, the outlet opening and the outlet container, wherein the spiral channel makes the liquid and gas mixture well separated from each other under the action of a centrifugal force, the outlet baffle blocks the liquid and gas mixture flowing out of the outlet of the spiral channel, which makes liquid in the liquid and gas mixture separated from gas for the second time when impacting the outlet baffle, and the separated liquid flows into the outlet container through the outlet opening; and compared with the prior art, the liquid and gas mixture is well separated.

Description

technical field [0001] The invention relates to automobile structure technology, in particular to an engine liquid-gas separation device, an engine and an automobile. Background technique [0002] When the automobile engine is running, the mixed gas in the combustion chamber of the engine has a great explosive force, which will cause a small amount of unburned mixed gas to return to the cylinder body through the gap between the piston ring and the cylinder wall. High temperature will cause a small amount of lubricating oil, fuel oil, etc. in the cylinder to vaporize into a liquid-gas mixture under the action of high temperature. The liquid-gas mixture is usually discharged through the air outlet on the engine cylinder head cover and enters the atmosphere or is introduced into the engine. Intake pipe. However, the above-mentioned liquid-gas mixture contains unburned fuel secondary harmful substances, and a small amount of fuel oil and lubricating oil, so that the above-menti...

AI Technical Summary

Problems solved by technology

Place three baffles 02, 03 and 04 on the cylinder head cover 05, so that a large amount of liquid mixture entering the separation chamber from the cylinder head passage 01 can pass through the obstruction of these three baffles to pass through the air outlet on the engine cylinder head cover 05 06 discharge, which plays a certain role in liquid-gas separation, but the effect of liquid-gas separation is not obvious; at the same time, using figure 1 and figure 2 The shown liquid-gas separation device processes the liquid-gas mixture, and the separated liquid mixture directly flows back into the cylinder body from the processing outlet hole (not shown in the figure) of the separation chamber, causing the problem of liquid-gas backflow
