Abstract
The utility model discloses a plastic air inlet manifold used for a vehicle engine. The plastic air inlet manifold used for vehicle engine comprises a resonant cavity, and a first gas passage, a second gas passage and a third gas passage which are communicated with the resonant cavity, and is characterized in that: a polyvinylchloride (PCV) pipe joint is arranged on the upper left part of the resonant cavity; a carbon tank control valve connecting pipe joint is arranged on the lower left part of the resonant cavity; a vacuum booster pipe joint is arranged on the lower right part of the resonant cavity; a sunken temperature pressure sensor installation plane is formed on the upper part of the shell of the resonant cavity; and two gas inlet manifold bracket installation structures are arranged on the lower part of the shell of the resonant cavity. According to the plastic air inlet manifold used for a vehicle engine, because the gas inlet manifold is designed by adopting a plastic material, the smoothness of the inner walls of the gas passages can be improved, gas inlet resistance is reduced, the gas inlet amount under various working conditions is improved, the performance of the engine is improved, moreover, the weight is light, and the cost is lower than that of an aluminum alloy gas inlet manifold; and because the gas passages have an S shape, the effective length can be increased in a narrow engine compartment, and the medium and low speed torques of the engine are improved.
Description
Technical field
The utility model relates to automotive engine component, is specifically related to a kind of plastic air intake manifold that is used for motor car engine.
Background technique
The lift-launch type with motor is generally mid-rear-guard on the minicar at present.For guaranteeing the clearance of motor, motor need tilt to place usually, causes engine compartment narrow and small.According to the usability of minicar, require motor that minicar carries in, low speed need have higher power and moment of torsion, and cost, oil consumption require lower.For satisfying above-mentioned requirements, a intake duct of design is long in narrow and small engine compartment, air inflow is sufficient, cost is lower and the unusual difficulty of intake manifold with certain resonant cavity volume.
Summary of the invention
The purpose of the utility model provides a kind of plastic air intake manifold that is used for motor car engine, and this plastic air intake manifold can satisfy following requirement: be suitable for the engine compartment space of the mid-rear-guard of minicar, compact structure; Air flue resonant cavity volume with certain-length; The air flue internal face is smooth, and the air inflow under each operating mode is sufficient; Beautiful shape, cost is relatively low.
The described a kind of plastic air intake manifold that is used for motor car engine of the utility model; Comprise resonant cavity; First air flue that is communicated with resonant cavity, second air flue and the 3rd air flue; It is characterized in that: a PCV pipe joint is located at the upper left quarter of resonant cavity, and a canister control valve connecting tube joint is located at the lower left quarter of resonant cavity, and a vacuum servo pipe joint is located at the lower right part of resonant cavity; The temperature and pressure transmitter mounting plane of one depression is located at the top of resonant cavity housing, and two intake manifold rack mounting structures are located at the resonant cavity lower part of frame.
Further, said resonant cavity, first air flue, second air flue and the 3rd air flue are provided with cross one another stiffening rib, with the distortion when reducing injection moulding of the intensity that improves intake manifold.
Further, said first air flue, second air flue and the 3rd air flue all are serpentine; Three air flues can provide enough inflammable mixtures for three cylinders of motor, and the air flue of serpentine can increase the effective length of air flue in narrow and small engine compartment, can improve in the motor, the moment of torsion of low speed.
The utility model is compared with existing technology and is had the following advantages: adopt plastic materials design intake manifold can improve the smoothness of air flue inwall; Reduce intake resistance, improved the air inflow under each operating mode, improved the performance of motor; And in light weight, cost is lower than aluminum alloy air inlet manifold; Because air flue is designed to serpentine, make air flue in narrow and small engine compartment, increase effective length, improved in the motor, the moment of torsion of low speed.
