Abstract: A fuel supply device mounted on an automotive vehicle includes a fuel pump and a sub-tank containing the fuel pump therein. The sub-tank and the fuel pump are submerged in fuel contained in a fuel tank. Operation of the fuel pump is controlled in a switching manner thereby to supply the fuel contained in the fuel tank to an internal combustion engine. When the fuel tank is made of a resin material, electromagnetic noises generated in the switching operation of the fuel pump are emitted from the fuel pump through the fuel tank, interfering with radio waves received by a receiver mounted on an automotive vehicle. To shield such noises, the fuel pump is disposed in the sub-tank that is made of a metallic material and grounded to a body of the vehicle. In this manner, the noises from the fuel pump are surely intercepted.

Abstract: On the upper portion of a cylinder head 1 of an engine mounted on a vehicle body in such a way that a crankshaft faces in the lateral direction of the body, a head cover 36 is supported in a floating state through an elastic member 14 and a rubber bush 52. A pair of TDC sensors 37i and 37e for detecting the rotational positions of engine camshafts 6i and 6e, are attached from the outside to the front surface and to the rear portion of the upper surface of the head cover 36 with bolts 38 respectively in such a way as not to interfere with a bonnet 39 of the body descending forward. Consequently, while ensuring the maintainability of the TDC sensors 37i and 37e of the engine, the TDC sensors 37i and 37e can compactly be attached to the engine.

Abstract: A screw pump having a pair of screw rotors meshed with each other and rotatably supported in a housing having an intake port provided at one end and a piston movably provided at the other axial end of the housing, which piston defines a discharge port in cooperation with the housing. The movement of the piston in a direction substantially perpendicular to the axes of the screw rotors enables the distance between a discharge starting position of the discharge port and the intake port to be varied, so that the internal compression ratio can be varied. This arrangement ensures that the size of the housing will not be increased and any disadvantage due to the difference in thermal expansion along the length of the housing can be overcome.
