摘要： PROBLEM TO BE SOLVED: To realize especially low fuel consumption in a partial load operation area while increasing torque in a heavy load operation area.
SOLUTION: The rotary piston engine 1 is constituted by housing a rotor 2 which partitions the rotor holding chamber 31 into three working chambers 8 and which performs each of the strokes of intake, compression, expansion, and exhaust in order while moving each of the working chambers 8 circumferentially by making planetary rotational movements about an output shaft X. The rotary piston engine 1 is provided with a first fuel injection valve 15 and a second fuel injection valve 16. The first fuel injection valve 15 directly injects fuel into the working chamber 8 which is in an intake stroke, and the second fuel injection valve 16 directly injects fuel into the working chamber 8 which is in a compression stroke. A control means 100 performs intake stroke injection by the first fuel injection valve 15 when the operating condition of the engine 1 is in the heavy load operation area, and performs fuel injection during the intake stroke by the first fuel injection valve 15 and fuel injection during the compression stroke by the second fuel injection valve 16 when the operating condition of the engine 1 is in the partial load operation area.

摘要： PURPOSE:To prevent a drop in engine rotational speed during return to fuel supply while ensuring minimum cooling ability by providing a means for changing the capacity of a compressor to a minimum value for a predetermined time during transition from the stop of fuel supply to the return to the fuel supply. CONSTITUTION:During deceleration of an engine 1, a fuel cut-off means stops the supply of fuel to the engine. During transition from the stop of fuel supply to the return to fuel supply, an actuator 25 is operated in response to an instruction signal from a control unit U so as to displace a suction port 23 opened to a side housing of a compressor 20 toward the rotationwise advancing side of a rotor 21 so as to set the capacity of the compressor 20 to a minimum value for a predetermined time. The load of the compressor 20 upon the engine is decreased to a value as small as possible during the period of return to fuel supply during which the fuel supply is unstable. As a result it is possible to prevent a drop in rotational speed of the engine 1 while ensuring a minimum cooling ability during return to fuel supply.

摘要： PURPOSE:To aim at making the comfortableness by air-condition and the startability of a vehicle coexist by providing a means for changing the capacity of a compressor to a minimum capacity for a predetermined time during start of the vehicle, and a compressor capacity retrieving means for gradually increasing the capacity of the compressor to a set value after the predetermined time elapsing. CONSTITUTION:During start of a vehicle, an actuator 25 is operated in response to an instruction signal from a control unit U so as to displace a suction port 23 opened to a side housing of a compressor 20 toward the rotationwise advancing side of a rotor 21 (indicated by the arrow) so as to change the capacity of the compressor 20 to a minimum value for a predetermined time. With this arrangement, the torque consumed for the drive of the compressor is decreased to a value as small as possible so that the torque produced by an engine is given to drive wheels as possible as it can, and accordingly the startability of the vehicle may be enhanced. Then, the suction port 23 is displaced by operating the actuator 25 after the predetermined time elapsing so as to gradually increase the capacity of the compressor 20 up to a set value, thereby it is possible to ensure the comfortability by the air-condition.

摘要： PURPOSE:To prevent carbon from adhering to a fuel injection valve, by injecting assist air in no relation to the injection of fuel when an engine is in fuel cut operation. CONSTITUTION:In a control unit 18, an engine is decided for whether it is in a fuel injection operation region or in a deceleration fuel cut operation region by an opening of a throttle valve 8 and an engine speed. The engine, when it is decided to be in the region of deceleration fuel cut operation, stops a fuel injection valve 10 while turns on a solenoid valve 11 injecting assist air from an air assist passage 9 toward the fuel injection valve 10. On the other hand, the engine, when it is decided to be in the region of fuel injection operation, promotes the atomization of fuel by injecting the assist air toward the fuel injection valve 10 by the predetermined timing synchronized with the injection of fuel. In this way, the engine, which injects the assist air even when the engine is in the region of deceleration fuel cut operation, effectively prevents the adherence of carbon to the fuel injection valve 10 caused by a reverse flow of exhaust gas.
