摘要： PROBLEM TO BE SOLVED: To reduce a variation of an injection quantity caused by split injection.
SOLUTION: The control device for the engine is provided with an injection timing setting means setting the injection timing of the main injection of fuel and the injection timing of each of a plurality of times of split injection after the main injection, and an injection execution means injecting fuel at the injection timing of the main injection and each split injection set by the injection timing setting means. The injection timing setting means sets the injection timing of the main injection by crank angles of the engine and sets the injection timing of the second split injection in terms of time so that the split injection is performed after a prescribed time elapses from the completion of precedent split injection.

摘要： PROBLEM TO BE SOLVED: To avoid cooling of an exhaust emission control device by surely increasing gas recirculation quantity to an intake passage from an exhaust gas passage even under a condition where exhaust gas pressure relatively drops in the exhaust gas passage during deceleration in an engine executing fuel cut, opening an EGR valve and closing an intake control valve during its deceleration. SOLUTION: In this deceleration control device, a control unit 30 executes fuel cut, opens the EGR valve 19 and closes the intake control valve 15, and controls a nozzle formed out of movable vanes 13b provided at a turbine part 13 of a variable capacity supercharger 11 disposed in the exhaust gas passage 3 at a downstream of a connection part with an EGR passage 8 to a close direction when a deceleration state of the engine 1 is detected by an accelerator opening sensor 34. Consequently, exhaust gas pressure at least at the connection part with the EGR passage 8 in the exhaust gas passage 3 is raised. COPYRIGHT: (C)2009,JPO&INPIT
