Background technique
In engine art, engine cold-starting is the thing that needs concern, and general motor is realized cold start-up by heater plug heating gas in the jar in the cylinder.But increasing the heater plug mounting hole in the cylinder cap makes the design difficulty of cylinder cap very big.The major function of gas handling system is for each cylinder of motor provides sufficient mixed gas uniformly, so the design of gas handling system is the key factor that influences engine power performance.The structure of traditional intake manifold is the form that adopts each air intake branch to arrange respectively, just becomes one at the suction port place, and this kind complex structure, present motor require the gas handling system of more and more compacter this structure to arrange very difficult.
The model utility content
In order to address the above problem, the purpose of this utility model is at problem recited above, provides a kind of simple in structure, integrated charge heating formula gas handling system, can reduce the design difficulty of cylinder cap, optimize the arrangement space of gas handling system again, satisfy the requirement to the motor compactedness.
For realizing top described purpose, the utility model is achieved by the following technical solutions.
A kind of used for diesel engine charge heating integrated form gas handling system, comprise: intake elbow, intake air preheater, intake manifold and cylinder cap, the as a whole pressure stabilizing cavity in the air outlet of described intake manifold, and at the mounting hole of the default described intake air preheater of suction port, described intake air preheater is fixedly mounted in the described intake manifold mounting hole, and end, described air outlet is provided with a plurality of bolt assembly departments, and be connected with described cylinder bolt, described intake manifold is connected by bolt flange with described intake elbow.
Preferably, also be provided with the intake manifold pad between described intake manifold and the described cylinder cap.
Preferably, also be provided with seal ring or sealing gasket between described intake manifold and the described intake elbow.
Preferably, described pressure stabilizing cavity is axial flat groove shape, and described mounting hole is located at the middle and upper part of described pressure stabilizing cavity, and relative with described pressure stabilizing cavity notch.
Preferably, described intake manifold tube wall is provided with the fixedly lug of fixed temperature pressure transducer or high-pressure oil pipe.
Effect of the present utility model is:
The utility model is simple in structure, and intake air preheater is fixedly mounted in the described intake manifold, has both reduced the design difficulty of cylinder cap, has optimized the arrangement space of gas handling system again.Described intake manifold is made the cavity of an integral body with four intake ducts, simplified manufacturing technique, and simultaneously whole gas handling system is arranged compacter, satisfies car load to the requirement in space, is very suitable for engine displacement at the vapour vehicle below the 3.5L or below the 4L.
