    摘要: An engine is provided with a variable valve mechanism capable of changing a degree of an operating angle and a phase of a valve-open period of an intake valve. A controller selectively executes at least one of a plurality of knock controls including a phase adjustment of the valve-open period of the intake valve when a knocking is detected by a knock sensor. When the operating angle of the intake valve is smaller than 180 degrees, a knock control is selected and executed such that a valve-open timing IVO of the intake valve does not exceed a predetermined timing (TDC+α) retarded from a top dead center TDC by a predetermined angle α. Specifically, for example, when the operating angle is smaller than 180 degrees and the valve-open timing IVO of the intake valve is after the top dead center TDC, the valve-open timing IVO is advanced.

    摘要: The power circuit device for vehicles is provided with a grounding portion for grounding portions closer to a power consumption device side than a relay of main conductive routes when the relays used for the main conductive routes extending from an accumulator of a vehicle to a fuel heating device, a catalyst heating device, an electric pump, or the like is turned OFF, so that a false power application is not executed even a short-circuit occurs in a part of a power circuit. Also, when two relays are arranged in series, the grounding portion is provided for the relay closer to the power consumption device in order to monitor a voltage level of the main conductive route and make it easy to detect a short-circuit or a disconnection occurrence.

    摘要: An intake device of an internal combustion engine is provided that includes an intake flow control valve shaped so as to be capable of effectively forming a tumble flow within a combustion chamber when there is a projection within an intake pipe located downstream of the intake flow control valve. The intake device of the internal combustion engine includes an intake flow control valve between a throttle valve provided within an intake pipe and a fuel injector located downstream of the throttle valve, for producing a tumble flow in a combustion chamber. The intake flow control valve includes a valve body. The valve body has a bypass airflow producing portion formed at a position corresponding to that of the fuel injector (i.e., a projection within the intake pipe) when viewed in a flow direction of the airflow. The valve body is shaped to have a projection, thereby allowing an airflow formed by the intake flow control valve to bypass the projection within the intake pipe located downstream of the intake flow control valve.
