    摘要: A valve control system for an internal combustion engine, which enables the operating mode of a valve system to be switched in optimal timing while preventing the driver from feeling the switching operation so busy and at the same time securing feeling of acceleration, thereby improving drivability. A variable valve-actuating mechanism is capable of selectively switching the operating mode of a valve system including intake valves and an exhaust valve between a plurality of operating modes different in output characteristics. Whether or not the operating mode of the valve system should be switched is determined. The execution of the switching of the operating mode of the valve system based on the determination is suppressed according to a degree of suppression set depending on detected load on the engine.

    摘要: An air inlet is provided at the bottom of a vehicle to open downwardly. The air inlet is connected by a first tube to an air cooler for a PDU and a down converter. A fan for inputting the flow of air and turning its direction 90 degrees is connected at the downstream of the air cooler. The fan is further connected by a second tube to an exhaust outlet. The air inlet is located above a fuel tank thus to prevent any object jumping up from the road surface from straightforwardly entering the air inlet while the vehicle is running. The exhaust outlet is located above a silencer and can thus be prevented from being frozen in the winter. Using the above arrangement, the present invention embodies an air intaking and exhausting apparatus in an air cooling system for air cooling the PDU and the down converter at higher efficiency without the help of the air cooler mounted in the interior of the vehicle.
