    摘要： A misfire-detecting system for an internal combustion engine carries out self-diagnosis of the system. In the system, sparking voltage generated across a spark plug of a cylinder of the engine is detected, and the detected sparking voltage is compared with a first predetermined reference voltage value, and a time period is measured over which the detected sparking voltage exceeds the first predetermined reference voltage value. It is determined that a misfire occurred in the engine when the measured time period exceeds a predetermined time period value. It is determined whether the engine is in self-sustaining operation. When it is determined that the engine is in self-sustaining operation, it is determined whether the misfire-detecting system is abnormal. It is determined that the misfire-detecting system is abnormal when the detected sparking voltage is lower than a second reference voltage value. Alternatively or in combination, it is determined that the misfire-detecting system is abnormal when the detected sparking voltage has continued to be higher than a third predetermined reference voltage value over a predetermined time period.

    摘要： A harness holder is disposed to extend along the inside of a cover member which covers a driving pulley and a timing belt, and a harness extending from a crank angle sensor is supported in the harness holder and prevented from contacting the belt and/or pulley. A locking claw projectingly provided at an end of the harness holder is fitted into a grommet mounted on the cover member to guide the harness 21 to the outside of the cover member. Thus, a fixing device such as a bolt for fixing the harness holder can be eliminated and moreover, a tip end of the locking claw can be visually observed from the outside of the cover member to confirm the mounted state of the harness holder.

    摘要： To provide a fuel injection device for controlling a fuel injection valve including a solenoid and a magnetostrictive element to generate a drive force for driving the fuel injection valve, the fuel injection device including: a solenoid power source (31) for driving the solenoid, a solenoid drive circuit (10) adapted to control the electrification to the solenoid by the solenoid power source (31), a plurality of magnetostrictive element driving power sources (32, 33) for driving the magnetostrictive element, and a magnetostrictive element drive circuit (20) adapted to control the electrification to a magnetostrictive coil of the magnetostrictive element by the magnetostrictive element driving power sources. Since the plurality of the magnetostrictive element driving power sources can be respectively used when performing a valve-opening operation and when performing a valve-closing operation of the fuel injection valve of the fuel injection device, the opening/closing operation of the fuel injection valve of the fuel injection device can be properly performed.

    摘要： In an intake valve lift variable engine including: an engine body; a cylinder head; an intake valve which is disposed in the cylinder head and which is controlled to be open and close so as to regulate the amount of intake air; and an intake system having no throttle valve and connected to the cylinder head, blow-by gas is sucked from a crank case of the engine body into a first pump and pressurizingly transferred by the first pump to the side of the intake system, and purge gas from a canister is mixed into the blow-by gas pressurizingly transferred by the first pump. Thus, the blow-by gas and the purge gas are guided to the intake system.
