Description
Technical Field
The utility model relates to an automobile engine technical field, in particular to automobile engine crankcase ventilation pipe.
Background
A ventilation system of an engine crankcase adopts a closed crankcase ventilation system at the present stage, on one hand, engine oil in waste gas is separated out, the consumption of the engine oil is reduced, the mixing contact of harmful substances in the waste gas and the engine oil is reduced, the influence on the quality of the engine oil is reduced, and the service life of the engine oil is prolonged; and on the other hand, crankcase combustion waste gas is introduced into an air intake system from a crankcase to be combusted again so as not to be discharged into the atmosphere to cause serious pollution to the atmosphere. If the crankcase ventilation line is disconnected, these harmful gases will be vented directly to the atmosphere. In addition, the waste gas of the crankcase also contains a certain amount of fuel steam, and when the waste gas of the crankcase flows through the ventilation pipeline of the crankcase, the fuel steam is easy to permeate out through the ventilation pipeline and the joint; in a shutdown state, along with temperature changes, a small amount of fuel contained in engine oil inside the engine can also become steam to flow to a crankcase ventilation pipeline and permeate out through the ventilation pipeline, and the steam can cause emission pollution of evaporative pollutants.
The existing ventilation pipeline is extremely easy to age and break after the circulation of high-temperature waste gas, so that the waste gas is leaked out, potential safety hazards are caused to the use, and the pipeline leakage is often found out not timely enough due to the fact that a leakage detection device is not arranged in the pipeline.
