Abstract
The utility model relates to a gasoline engine, in particular to a gasoline engine air intake system, which comprises a front air intake pipe assembly, an air filter assembly, a resonator and an air exhaust pipe, wherein the air filter assembly consists of a lower cavity body, an upper cover and a deflector which is a flat plate structure with netted reinforcing ribs, arranged inside an air filter and divides an inner cavity of the air filter into a first cavity chamber and a second cavity chamber; the first cavity chamber is communicated with a front air pipe and the resonator; and the air filter is arranged inside the second cavity chamber which is communicated with the air exhaust pipe. By arranging the deflector in the air filter assembly of the gasoline engine air intake system, air inflowing from the front air intake pipe is split via the deflector and then simultaneously enters the air filter and the resonator, the combined action of the air flow inside the air filter and the air flow inside the resonator reduces and eliminates specific high-frequency noise and low-frequency noise to effectively improve noise reduction effect.
Description
Technical field
The utility model relates to a kind of petrol engine, particularly relates to a kind of gasoline engine intake system.
Background technique
The component aggregate of air or mixed gas importing cylinder is called engine aspirating system, mainly comprise air-strainer, intake manifold and intake valve mechanism, air is after air-strainer filters out impurity, flow through Air flow meter, enter intake manifold via admission line, mix the oil gas that the back forms proper proportion with the gasoline of oil sprayer ejection, send into ignition in the cylinder, produce power by intake valve.Therefore, the major function of gasoline engine intake system is to carry the air of cleaning to engine intake manifold, will reduce the noise that gas flow produces simultaneously.Layout, pipeline structure design that gas handling system not only requires profile will help in the engine nacelle will guarantee that suction tude is indeformable under negative pressure, also require hydrodynamic noise low, be beneficial to draining.But vibration and noise were bigger when existing petrol engine was worked.
The model utility content
Technical problem to be solved in the utility model is vibration and the bigger problem of noise when solving petrol engine work.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopted provides a kind of gasoline engine intake system.Suction tude assembly, air cleaner assy, resonator and steam outlet pipe before comprising, described air cleaner assy comprises lower chamber, loam cake and guide plate, suction tude assembly and steam outlet pipe are installed in respectively and cover before described, described resonator is installed on the lower chamber, described guide plate is the slab construction with netted reinforcing rib, the inside that this guide plate is arranged on air cleaner assy is separated into first, second two chambers with its inner chamber, wherein first chamber communicates with preceding suction tude assembly resonator, is provided with air-strainer in second chamber and communicates with steam outlet pipe.
In the such scheme, described suction tude assembly comprises upper and lower body and the draining box that fastens installation up and down, and the lower surface of described lower tube body is provided with some through holes, and described draining box is fixed on the lower surface of lower tube body.
Described outlet pipe is curved, and is provided with two place's ripple pars contractilis, and the outer convex globoidal that is positioned at the steam outlet pipe of two ripple pars contractilis intermediate portions is provided with latticed stiffening rib.
The utility model, be provided with guide plate in the lower chamber of air cleaner assy, the air of coming in from suction tude enters the air-strainer resonator, the two acting in conjunction simultaneously after the guide plate shunting, alleviate and eliminate specific high and low frequency noise, promoted the effect of noise reduction effectively.
