Abstract
PURPOSE: To improve the performance of combustion at low speed and to reduce the generation of harmful component of exhaust gas during deceleration by introducing air to the combustion chamber through the bypass provided to the internal combustion engine at low speed and during slowdown.
CONSTITUTION: The suction air bypass 54 which is tangently communication to the combustion chamber not shown in Figure is provided parallelly to the main suction passage 30 equipped with the throttle valves 58, 59. The tip end of bypass is opened in the upper stream when the throttle valve 59 is full closed through the air control valve 66. In the negative pressure chamber 106 of the control valve 66, the valve 100 is opened when the high negative pressure of suction pipe operates at low speed and slowdown while the throttle valve 59 is slightly opened, air is tangently introduced to the combustion chamber. Also the exhaust passage not shown in Figure and the main suction air passage 30 are communicated to each other through the reflux passage 72, on which the first and second control valves 74, 76 that are opened and closed by the thermovalve 90 and the negative pressure switch 122 are provided.
