Abstract

PURPOSE: To improve the starting characteristic of the engine by a method wherein some cylinders are kept stopped at the time of starting the engine and at the same time the exhaust gas from injection side cylinders is returned to the stopped cylinders without introducing fresh air into the latters.
CONSTITUTION: When a switch 28 is turned ON in the starting condition of the engine, an electromagnetic valve 34 is energized so that the fuel is injected into the cylinders 10aW10c. In this case, a regulator switch 30 also turns ON to make the contact of a relay 27 go OFF so that electromagnetic valves 24 and 35 are not energized resulting in making the cylinders 10dW10f inoperative. Simultaneously with the above operation, valves 15 and 18a are closed due to the introduction of air into actuators 14 and 21 and a valve 18b is opened. Consequently, the high temperature exhaust gas from the injection cylinders is returned to the stopped cylinders and no fresh air is supplied into the latter cylinders.
