Description

A kind of motor car engine pressurized intake device

Technical field

The utility model relates to a kind of improvement of air inlet device for automobile engine, specifically a kind of motor car engine pressurized intake device.

Background technique

As everyone knows, in conventional engine work, comprise air-breathing, compression, outburst, four strokes of exhaust, in suction stroke, air enters in the cylinder by suction tude, air-strainer is also established in outer end in suction tude, the vapour internal combustion oil of cylinder contact with air more abundant, combustor inner cylinder more abundant, the energy that discharges are also just more, the power of motor is also just larger, HC in the waste gas that gives off, CO, NO is just fewer, and therefore, the gas flow that enters in the engine working process in the cylinder is very important, so the air inflow that increases each work cycle of engine cylinder is the key point that changes engine performance.At present, increase engine cylinder air inflow existing report aspect motorcycle cylinder, but aspect Motor Engine Cylinder, yet there are no report.The Motor Engine Cylinder air inlet system is made of air intake branch, intake manifold and air-strainer at present, air intake branch is connected with the upper end of Motor Engine Cylinder, intake manifold's front end is connected with air intake branch, intake manifold's rear termination air-strainer, in suction stroke, air is from air-strainer, in intake manifold, air intake branch enter respectively each cylinder, its deficiency just is that its air inflow is natural inflow, do not add pressurized intake device, cause the performance of Motor Engine Cylinder can not reach the optimum state.

Summary of the invention

The purpose of this utility model is the Motor Engine Cylinder pressurized intake device that a kind of operation simple in structure, easy is provided, can improves the Motor Engine Cylinder performance.

For reaching above purpose, the technological scheme that the utility model adopts is: this motor car engine pressurized intake device, by cylinder, air intake branch, the intake manifold, air-strainer consists of, intake manifold's front end is connected with air intake branch, air intake branch is connected with the upper end of each cylinder of motor car engine, it is characterized in that connecting roll-over valve in intake manifold's rear end, side joint mouth on the roll-over valve is connected with air-strainer by conduit, the lower mouth that connects on the roll-over valve is connected with the outlet nozzle of pneumatic pump by corresponding conduit, and the air inlet nozzle of pneumatic pump is connected with air-strainer by corresponding conduit.The utility model is also implemented by following measure: the starting electrical machinery of described pneumatic pump is connected with solenoid valve by wire, take car as example, turn following and when 3500 turn above 3000, closed electromagnetic valve, in the time of only between 3000-3500 turns, solenoid valve is just opened, and carries out pressurization air inlet in the countercylinder; Owing to turning above 3500, the air pressure air pump inoperative so avoided the generation of engine high pressure gas, can not exert an influence to the work of motor; The control of solenoid valve can be connected with the tachometer of car by wire, and the startup of pneumatic pump can be in the following ways: the one, by the control of solenoid valve, can be connected with the tachometer of car by wire, and this kind connecting means does not need motor is transformed; The 2nd, in operator cabin, establish hand switch, by the work of hand switch control pneumatic pump; The 3rd, pneumatic pump is connected with automobile current generator by belt transmission or gear transmission, this kind connects to be needed motor is done corresponding the improvement, when 3000 turn above, blows the turbine flabellum by discharging waste gas and rotates, the turbine flabellum drives pneumatic pump work again, realizes the countercylinder supercharging; Described roll-over valve, by the square tubular housing, upper adapter, under connect mouth, the side joint mouth, turnover board consists of, on the upper adapter access intake manifold, on the conduit of side joint mouth access air-strainer, connecing down mouth is connected with the corresponding pipe of access pneumatic pump, turnover board is fixed on the interior opening's edge downside of side joint mouth by rotatingshaft, the width of turnover board is consistent with the inner chamber width of square tubular housing, the height of turnover board is advisable with the top that can be tilted in oppose side wall, under the closed electromagnetic valve state, turnover board is swung to down by self gravitation and is connect mouth, and at this moment, natural atmosphere enters the intake manifold through air-strainer by conduit and side joint mouth; When solenoid valve was opened, pneumatic pump started, and to intake manifold's inflation of pressurizeing, turnover board upwards promotes, and with the shutoff of side joint mouth, pressurization is inflated in the countercylinder.

The beneficial effects of the utility model are: be the pressurized intake device of 3000-3500 when turning owing to having added in the speed of a motor vehicle, so that the performance of Motor Engine Cylinder is improved, make the power of motor car engine obtain expansion.
