Abstract
PURPOSE: To ensure fixed output, by preventing the generation of exhaust noxious components by setting an air fuel ratio at the concentrated side and flowing back exhaust while compensating output in a low car speed range and by reducing exhaust reflux and by releasing the set of the air fuel ratio at the concentrated side in a high-speed range.
CONSTITUTION: An air fuel ratio controller 5 is incorporated into a carbureter 4 adjusted being one-sided to more concentrated side than a theoretical air fuel ratio. Thus, concentrated mixture is fed under a condition that a by-path air passage 7 is closed and thin mixture under a condition that the passage 7 is opened. An exhaust reflux quantity controller 13 connected to a valve body 12 of an exhaust reflux 11 passage joining an exhaust passage 10 and an intake passage 2 adjusts the opening of an exhaust reflux control valve 17 relating to intake negative pressure. An angle of the lead of ignition timing is delayed by means of an ignition timing controller 27, to which a negative pressure signal passage 27 is connected, at the same time. Thus, the mixture of an air fuel ratio at the concentrated side and exhaust flowed back at a fixed exhaust reflux ratio are sucked to an engine 1 in a low car speed range.
