Abstract

PURPOSE: To prevent knocking and improve sufficient supercharging effect by driving a turbocharger with the exhaust pressure of the suspension side cylinders which cease operation in light loading.
CONSTITUTION: When an engine is operated in high loaded state, a shut-off valve 7 is open and a recirculating valve 6 is closed, and fuel is supplied to all cylinders #1W#6, and all cylinder operation is performed. The exhaust turbine 8 of a turbocharger 10 is driven by the exhaust pressure of the cylinders #4W#6. When the supply of fuel to the cylinders #4W#6 is intercepted in the light loaded state of the engine, the shut-off valve 7 is closed at the same time, and also air is cut, and the engine continues operation with only cylinders #1W#3. Then, the recirculating valve 6 is opened, and the air exhausted from the out-of-operation cylinders #4W #6 passes through a recirculation passage 5 and is recirculated to the intake side, and thus generation of pumping loss can be prevented.
