Abstract

PURPOSE:To obtain the supercharged engine of a high performance with a simple constitution and a low cost by a method wherein a suction pipe, communicating with a suction valve device provided in a space including the back surface of a piston, is communicated with the side of a throttle valve via the space including the front surface of the piston. CONSTITUTION:The piston 1 is constituting the four cycle engine together with an exhaust valve 2 and a suction valve 3, both driven by a normal method. Here, an air pump is constituted in the space including the back surface of the piston 1 by the suction pipe 6, equipped with a throttle valve 7 and an one-way valve 4, and another one-way valve 5. The discharging side of the one-way valve 5, operating as a discharging valve, is connected to the suction valve 3 of the engine via the suction pipe 6. In such four cycle engine, air is sucked once every two rotations, however, the piston 1 is reciprocated one time at every one rotation of the engine. Accordingly, the air pump, consisting of the back surface of the piston 1 and the one-way valves 4, 5, can supply the two times of the maximum value of an air volume consumed on the upper surface of the piston 1.

なる欠点がある。The maximum output of an internal combustion engine is limited by the amount of air sucked into the cylinder. Therefore, it is known that the maximum output can be increased by supplying pressurized air to the engine by some means. Conventional devices used for this purpose include turbochargers and Roots blowers. By the way, in a turbocharger, the exhaust gas is used to drive the turbine and the turbo blower is used to create compressed air, so when the engine is at (Ilt) speed, the amount of exhaust gas is insufficient and sufficient pressure cannot be generated. , because the turbine rotor has inertia, there is a disadvantage that pressurization is delayed during sudden acceleration.On the other hand, mechanical compressors such as Roots blowers do not have the disadvantage of 10P, but they have a pressure of 1M separate from the engine. Since it is equipped with a machine, it is expensive and also occupies a large space.

この発明は上記の点に鑑みてなされたもので、耶下この
発明の一実施例を図について説明する。This invention has been made in view of the above points, and one embodiment of this invention will now be described with reference to the drawings.

に溶料を供給する。In the figure, a piston (1) constitutes a four-stroke engine together with an ejection valve (2) and an intake valve (8) which are driven in a conventional manner. An intake pipe with a throttle valve (7) and a one-way valve (4) in the space including the back surface of the piston (1), and a one-way valve (
5) constitute an air pump. The discharge side of the one-way valve (5), which functions as a discharge valve, passes through the intake pipe (6) to the engine intake valve (
8). Fuel injection system ff! l (8) supplies the engine with solvent.

) can supply twice the maximum amount of air consumed by the piston + dIj.

。In other words, up to twice the supercharging is achieved. If the opening position quotient of the suction valve (8) device is set in the direction of the binuton surface, this magnification is 2.
A supercharger that can be arbitrarily set within a smaller range can be obtained by using a small heater inside the engine, and an engine that is low cost and occupies a small space cannot be obtained. In addition, since the pump operating force ζ is in a reverse relationship with the piston operation, there is no delay in empty consumption.
