PURPOSE:To reduce output loss, and to improve fuel cost by setting up clutches among the crankshafts of each cylinder of a multicylinder engine and interrupting the supply of fuel to partial cylinders on light load while declutching the clutches of the cylinders. CONSTITUTION:Each piston 18-21 of the cylinders G-I, the supply of fuel thereto is interrupted and operation thereof rests on light load, and the cylinder J operated at all times is connected to the crankshaft 23 through several connecting rod. The crankshaft 23 is divided into four in response to the number of the cylinders, and connected through the clutches 26-28 among respective cylinder. A control circuit 34 inputs the number of revolution, load, crank angles, etc., and interrupts the supply of fuel into the cylinders G-I in a light load region on the basis of these signals while declutching the clutches 26-28. The operation of the pistons of cylinders under suspension can be stopped, output loss in case of the operation of partial cylinders is reduced, and fuel cost can be improved. |
