Description
Technical field
The present invention relates to auto parts machinery field, particularly a kind of motor intake manifold.
Background technology
In China, the development of automobile industry and plastic manufacturing process is advanced by leaps and bounds, the engine fittings that metal makes are replaced by the engine fittings of the plastic production taking intake manifold as representative gradually, as one of the parts of engine most critical, intake manifold achieves in automobile industry and applies widely, its Core Feature is for each cylinder of engine provides full and uniform gas mixture, is the key factor affecting engine forces and oil consumption.
When automobile travels at the environment that temperature is very low, special picture waits very cold region northeastward, and rubber accessory flexibility decrease at low ambient temperatures brittle failure occurs, causes gas leak of the oil leakage etc., directly affect the safety traffic of automobile.
Therefore, how to replace existing metal to make motor intake manifold with suitable plastic material, improve the quality of rubber accessory in cold environment, have great importance.
Summary of the invention
For solving above-mentioned the deficiencies in the prior art, the present invention proposes a kind of low temperature resistant intake manifold resonator cavity.
Technical scheme of the present invention is achieved in that
A kind of low temperature resistant intake manifold resonator cavity, each intake manifold arm 3 upper end air throttle 1 is communicated with intake manifold resonator cavity 2, each air outlet, intake manifold arm 3 bottom is connected with each cylinder head respectively by joint flange 4, also comprise gas rail 5 and multiple gas rail connecting branch 6, gas rail connecting branch 6 and intake manifold arm 3 one_to_one corresponding, gas rail 5 is communicated with the lower end of each intake manifold arm 3 by gas rail connecting branch 6;
Described intake manifold resonator cavity 2 is made up of cold resistant rubber, and this cold resistant rubber contains following component and weight part: 100 parts, silicon rubber, white carbon black 50 parts, Diphenylsilanediol 4 parts, ferric oxide 2 parts, dicumyl peroxide 0.5-2 part.
The invention has the beneficial effects as follows:
(1) can be used in inside motor car engine, reduce the loss that low temperature environment causes rubber brittle rupture;
(2) improve reliability and the work-ing life of Whole Equipment further, automobile is driven safely.
