Problems solved by technology

At this time, the flow rate of the blow-by gas will also decrease. If the blow-by gas with a smaller flow rate passes through the nozzle holes 4, 4' whose total area is set based on the maximum flow rate, the flow rate of the blow-by gas will be slower than the appropriate level. , so there is a problem that the separation of engine oil is not smooth

Abstract

The present invention discloses an impingement type breather device for separating engine oil from blow-by gas flowing into a crankcase of an engine. The impingement ventilation device according to the embodiment of the present invention includes: a gas inflow part into which the blow-by gas flows; a nozzle part formed with a nozzle hole through which the blow-by gas flowing in through the gas inflow part passes; a collision part, The blow-by gas passing through the nozzle hole collides with the collision part; a gas discharge part for discharging the blow-by gas passing through the nozzle hole; and an adjustment mechanism corresponding to the pressure of the blow-by gas Adjust the total open area of ​​the nozzle hole accordingly.

Description

technical field [0001] The present invention relates to an impingement breather device for separating engine oil from blow-by gas flowing into a crankcase of an engine, and an engine including the impingement breather device. Background technique [0002] A vehicle is equipped with an engine as one of driving sources for driving the vehicle. The engine converts thermal energy into mechanical energy to generate driving force. In a plunger type engine, combustion of fuel causes a plunger to reciprocate in a cylinder, and the reciprocating motion of the plunger is transmitted to a crankshaft to be converted into rotational motion. [0003] At this time, when the plunger is reciprocating, through the gap between the inner wall of the cylinder block and the plunger, a small amount of mixed gas will leak from the combustion chamber to the crankcase, and this mixed gas is called blow-by gas (Blow-by gas). -By Gas). Since the blow-by gas includes unburned fuel, combustion gas and...
