Description
Technical field
The utility model belongs to combustion engine unit, specifically a kind of exterior line Integration Design crankcase ventilation system
System.
Background technology
Engine at work, high pressure combustion mixture in combustion chamber and already gas can be by between piston and cylinder
Gap leak into engine crankcase（That is crankcase gas blowby）.Because crankcase gas blowby includes unignited oil gas and vapor,
Being directly discharged into air can pollute to environment, so needing crankcase gas blowby being reintroduced back to engine aspirating system, that is, close
Formula PCV system.With the increasingly raising of emission regulation demands, newest state six is added to crankcase in requiring
Ventilating system integrality（Air pipeline disconnects）Carry out OBD monitoring.
Utility model content
The purpose of this utility model is to provide a kind of exterior line Integration Design crankcase ventilation system, fundamentally solves
Determine above mentioned problem, it has the advantages that simple and compact for structure, low cost, easy to use.By to original crankcase ventilation system
Three passages being connected with engine aspirating system of uniting carry out Integration Design with engine crankcase structural member, only retain one
The exterior line led to after air filter, a crankcase ventilation pipeline is only monitored so as to reduce engine assembly number of parts and realize
Can meets the regulation of state six to crankcase ventilation system pipeline OBD monitoring requirements.
To achieve the above object, the utility model provides following technical scheme：The exterior line Integration Design bent axle
Box ventilation system includes the circulation air flue being arranged between crankcase, cylinder body and oil sump, is characterized in that：The crankcase
It is connected respectively by air inlet side gas blowby pipeline and exhaust side gas blowby pipeline with oil sump, gs-oil separator is provided with crankcase,
Return flow line is provided between gs-oil separator and cylinder body；Crankcase inlet end is provided with air cleaner, air cleaner and bent axle
Air filter house steward is provided between case, air filter integrated pipeline, air filter integrated pipeline and song are provided between air filter house steward middle part and crankcase
Air filter branch road is provided between axle box, tonifying Qi pipeline is provided between air filter integrated pipeline and cylinder body, increasing is sequentially provided with air filter house steward
Depressor, charge air cooler and air throttle, Dilution air pipeline, inlet manifold branch road are set gradually between air throttle and crankcase, is entered
Check valve is respectively equipped with gas manifold branch road, tonifying Qi pipeline and air filter branch road, Stress control is provided between check valve and crankcase
Valve.
The beneficial effects of the utility model：The description of crankcase ventilation system integrality is monitored to OBD according to regulation, effectively
Crankcase ventilation system external engine piping is reduced, former pipeline progress integrated approach, which can be reduced effectively, needs crankcase
Ventilating system OBD control points, while assembling amount of parts is reduced, improve engine integrated design.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Description of reference numerals：1 air cleaner, 2 air filter house stewards, 3 tonifying Qi pipelines, 4 air filter integrated pipelines, 5 air filter branch roads,
