Abstract
The utility model discloses a gas engine variable air intake system which can solve the problems as complex structure, high cost, and etc. of the electrical control variable valve timing system for the current gas engine, and has the advantage of simple structure, low cost, greatly improved convenience property for the matching. The structure of the utility model: comprising an external air pipe whose one end is connected with the valve through an air intake connecting pipe which is internally provided with an open or closed transfer valve that is provided with a check valve.
Description
Technical field
The utility model relates to a kind of induction system of internal combustion engine, relates in particular to a kind of novel internal-combustion engine variable gas handling system that prevents the refluence of air-intake of combustion engine process gas.
Technical background
In order to improve the intake efficiency of internal-combustion engine, the intake valve of internal-combustion engine in intake process need piston not to budc begin to open, piston is to closing after bottom dead center, the angle that the high more intake valve of internal-combustion engine rotational speed is early opened late pass is big more.Desirable intake process should be that the engines distribution phase place changes promptly with engine speed change: the angle that intake valve is early opened late pass during high rotating speed greatly, the angle of early opening late pass during the slow-speed of revolution is little, in order to realize above-mentioned requirements, modern advanced internal-combustion engine has adopted the electronic control variable gas distribution timing system, but this system changes the inlet valve cam axle position to realize above-mentioned requirements, its complex structure cost height.
Summary of the invention
The purpose of this utility model is exactly in order to solve present internal-combustion engine problems such as electronic control variable gas distribution timing system complex structure cost height, provide a kind of have simple in structure, with low cost, supporting convenient function such as significantly improves at the internal-combustion engine variable gas handling system of advantage.
For achieving the above object, the utility model adopts following technological scheme:
A kind of internal-combustion engine variable gas handling system, it comprises outside tracheae, described outside tracheae one end taps into valve through air inlet tube; The switch valve that can open or close is housed in air inlet tube, one-way valve is housed on switch valve.
Described air inlet tube is connected with outside tracheae by carburetor throttle.
Described outside tracheae also is connected with the pneumatic servo control valve, and it is connected with air inlet tube.
Described outside tracheae connects solenoid valve, and solenoid valve is connected with pneumatic pilot valve with electronic controller respectively, and the pneumatic servo control valve is connected with air inlet tube.
Described one-way valve is the reed-type one-way valve.
Described pneumatic servo control valve is a diaphragm valve or solenoid valve.
Described solenoid valve is a direct current two-bit triplet electromagnetic valve of gas circuit.
Internal-combustion engine of the present utility model adopts variable volume intake system, and it mainly comprises DXFS air inlet tube, pneumatic servo control valve, DXFS air inlet tube and solenoid valve four parts.Optimum condition design when motor is joined the gas handling system cam by high speed operation, both had bigger intake valve and early opened late pass angle, electronic controller is connected electromagnetic valve current during high engine speeds work, electronic controller is made up of electronic parts and components, by accepting fire signal, judge engine speed. be switched on or switched off external circuits.Solenoid valve armature is connected the pipeline of suction tude to the pneumatic servo control valve.Pneumatic pilot valve switches to pass-through state with the DXFS air inlet tube under the suction pressure effect, realize high-power requirement to reduce intake resistance loss increase air inflow, in during tick-over electronic controller pass through solenoid valve. the pneumatic servo control valve switches to the one-way valve working state with the WHL air inlet tube, and open waste gas is flow backwards the morning that prevents intake valve.Close the evening of intake valve and make the mixed gas backflow, improve the low speed air inflow. reduce exhaust gas inside cylinder content, improve burning and make power raising, rate of fuel consumption and discharging reduction.
The beneficial effects of the utility model are: simple in structure, with low cost, supporting convenient function significantly improves, and can reduce exhaust gas inside cylinder content, improves the air inlet charge, and oil consumption is reduced, and power improves, and discharging improves.
