A semiconductor device includes: a first transistor having a control electrode coupled to an input node receiving a signal synchronized with a clock, a first conductive electrode coupled to an output node, and a second conductive electrode; a second transistor having a control electrode coupled to the input node, a first conductive electrode coupled to the output node, and a second conductive electrode coupled to a power supply node; and a first switch element connected between the power supply node and the second conductive electrode of the second transistor and turned on and off based on a first control signal indicating a detection result of a frequency of the clock.

Semiconductor device reducing leakage current of transistor

A fuel injection control system for an internal combustion engine having a fuel injection valve located near an intake port can control the timing of fuel injection in synchronism with engine revolution. The fuel injection control system improves fuel atomization characteristics and uniformity of air/fuel mixture entering the engine cylinders. The control system controls the fuel injection timing so that the fuel injection occurs within a valve-overlap period during which an intake valve and an exhaust valve are both open. In order to precisely control the fuel injection timing, the piston stroke of each engine cylinder is detected with reference to the crank shaft angular position.

Fuel injection timing control system for internal combustion engine and

An automotive internal combustion engine having main and auxiliary combustion chambers for each of the cylinders and combined with a carburetor is provided with an air-fuel mixture induction system which comprises an intake manifold providing communication between the carburetor and each of the main combustion chambers, characterized by passageways leading to the auxiliary combustion chambers and open into the intake manifold or the intake ports for the main combustion chambers through an opening in the main tube portion of the intake manifold, openings respectively formed in the runner portions of the intake manifold or openings formed in wall portions defining the intake ports for the main combustion chambers.
