Title: Suction apparatus of engine
Inventor: ISHIDA ATSUJI
IPC: F02B31/00
Filed: 1980-12-29
Abstract: PURPOSE: To make driving with low load smooth, and to improve the thermal efficiency and the counter measures for exhaust gas problems, by connecting a valve mechanism, which can open and close synchronously with the suction timing of an engine, with a suction passage of the engine.  
     CONSTITUTION: The cam shaft 1 of the engine is rotated coactively with a crank shaft to open and close a suction valve and an exhaust valve. A valve housing 7 has radially arranged passages 13 positioned to correspond with passages 12 in a rotor 5 so as to form the valve mechanism. Since the rotor 5 rotates integrally with the cam shaft 1, the opening and closing of the valve mechanism is synchronized with the suction timing of the engine. A fluid inlet 16 is connected with a caburator, and the passages 13 are connected with the combustion chamber of the engine. A mixed gas or air is introduced from the fluid inlet 16 via passages 15, 14, 11, 12, 13 into the combustion chamber. Thus, a swirl is generated, and the combustion speed is increased so that stabilized combustion can be performed.
