Document Type and Number:
Japanese Patent JP2002276398
Kind Code:
A
Abstract:
To impart a smooth flow to an air-fuel mixture getting in and out from a valve [piston valve (valve b)] or air opening [rotary valve (air opening c)] opened in an intake stroke and closed after starting a compression stroke in the use of a piston valve or rotary valve to a 4-cycle gasoline engine or 6-cycle gasoline engine.
The valve b or air opening c are divided to two kinds of a valve (valve d) or air opening (air opening e) opened in the intake stroke and closed in a bottom dead center and a valve (valve f) or air opening (air opening g) opened in the bottom dead center and closed after starting the compression stroke.
