Abstract
PURPOSE: To improve an engine brake action of a cylinder number control engine of the type wherein some of cylinders are kept at rest during low running by cutting fuel supply and rendering the rested cylinders again into operative while deceleration.
CONSTITUTION: Suction and exhaust manifolds 10, 13 are partitioned respectively into operating suction and exhaust manifolds 10a, 13a and resting suction and exhaust manifolds 10b, 13b. An opening and closing valve 15 is interposed between both suction manifolds 10a, 10b which is controlled by an actuator 18, and an EGR valve is interposed between the resting manifolds 13a, 13b which is controlled by another actuator 19. During low load running of the engine, the opening and closing valve 15 is closed and the EGR valve 16 is opened. While deceleration during low load running, a cylinder number limiting circuit 25 adapted to receive a signal from a control circuit 24 is released to cause a magnet valve 20 to release both actuators 18, 19 so that the opening and closing valve 15 is opened while the EGR valve 16 is closed.
