Title: Suction device for internal-combustion engine
Inventor: KOTANI AKIRA
IPC: F02D9/02
Filed: 1984-02-07
Abstract: PURPOSE:To prevent the occurrence of anything unusual in an air-fuel ratio caused by suction of unburned gas sticking to a suction control valve in time of throttle full-open and the worsening of exhaust gas emission control pursuant to that, by making the suction control valve so as to be fully opened at a time when a throttle valve is fully closed. CONSTITUTION:At a low- and medium-speed in an engine, a suction control valve 8 is closed, and suction air flows into a combustion chamber from one suction port 3. At a high-speed range in the engine, the suction control valve 8 is opened, and thereby the suction air flows into the combustion chamber from two suction ports 3. And, in time of idling or deceleration a throttle valve becomes fully colsed, the suction control valve 8 comes to open. In time of said idling or deceleration, if the suction control valve 8 is closed by prefiring in an overlap, unburned gas sticking to the suction valve 8 is sucked in the combustion chamber by dint of a high vacuum whereby proper combustion is hampered. However, in time of idling or deceleration, the suction control valve 8 is set free so that the unburned gas is prevented from sticking to the valve.
