  • Patent number: 6688288
    Abstract: An internal combustion engine such as a multi-cylinder in-line engine having on one side of the cylinder head an air induction system and on the opposite side an exhaust system, each extend generally in the direction of the length of the engine. Each of said systems extending above the level of a cylinder head of the engine and a fuel rail is provided extending in the direction of the length of the engine and mounted on the cylinder head to be located between the air induction system and the exhaust system. The fuel rail overlies and is in fuel transfer communication with respective fuel injector units mounted in the head of each cylinder of the engine. Preferably, the fuel rail is configured so as to provide sufficient clearance on the exhaust side thereof to enable spark plugs to be appropriately arranged within the cylinder head on the exhaust side thereof.

  • Patent number: 5904126
    Abstract: A control system and method for controlling a pump having a fluid passage therein, including a sensing means for sensing fluid flow through the fluid passage wherein the control system controls the actuation period of the pump as a function of a characteristic of the fluid flow sensed by the sensing means. The sensed characteristic is the quantum rate of fluid flow through the fluid passage.

  • Patent number: 5516309
    Abstract: A terminal assembly for a cable having a multiplicity of conductors, particularly having a relatively high number of small gauge conductors, and providing an individual terminal for each conductor. The terminal assembly comprises a terminal block having a plurality of terminal cavities at one face of the block to receive respective terminal elements and a plurality of conductor apertures in the opposite end of the terminal block. The respective conductors with or without a terminal element connected thereto pass through each conductor aperture to be connected to a terminal element in, or to be located in, a respective terminal cavity. Locking means are provided of the terminal block adapted to anchor each conductor to the terminal block to thereby limit the transmission of cable or conductor movement externally of the terminal block to the terminal elements.
