Abstract: In a liquid infusion apparatus, an incremental linear encoder is arranged along the feeding shaft direction of the liquid infusion apparatus to directly monitor the movement and position of a carriage part which applies an action to a plunger. A detecting sensor is provided at a starting point of a remaining liquid quantity small region to recognize the absolute position at said region by using feed-back pulses from said encoder.

Abstract: A scroll compressor is provided with a reverse rotation detection circuit that monitors the temperature adjacent the suction tube. An elevated temperature at the suction tube is indicative of reverse rotation, and if the temperature exceeds a predetermined maximum, then a determination is made that reverse rotation is occurring. Once this determination is made, the rotation of the motor is stopped, or corrected.

Abstract: A fuel system provides first and second conduits that draw fuel from first and second positions, or locations, within a fuel reservoir. If water exists in the fuel reservoir, the second position is selected to be lowered in the fuel reservoir than the first position so that accumulated water will be drawn through the second conduit under certain conditions, such as when the engine is operating at a speed above the minimum threshold. The fuel reservoir can be a fuel tank or auxiliary fuel tank of a vehicle or watercraft or, alternatively, it can be the housing of a fuel/water separator.

Abstract: A method for determining ignition angles for individual cylinders in a multicylinder internal combustion engine forms the ignition angles for the individual cylinders, based on values of a basic family of characteristics (KFB) which applies to all cylinders, as a function of a knocking behavior of the internal combustion engine on the basis of a first (fast) and second (slow) adaptation loop. Once the internal combustion engine has been stopped, the values that are present are used in a third adaptation loop to form a family of characteristics (KF3) which is applicable to all cylinders (z), and a shift value (ZW3(z)) for each cylinder. These are stored in a non-volatile manner.

The controller has a microprocor that will provide a current to the glow plugs until they are heated to the desired operating temperature and will then distribute sequential pulses to the individual plugs until the engine reaches the desired operating temperature. The system can have a latching circuit that will prevent the preglow cycle from being reinitiated until the glow plugs have been allowed to cool to a level where reinitiation will not represent a substantial degrading effect on the glow plugs.

Abstract: Disclosed is a method of operating an internal combustion engine (20) with a fuel injection system (11;12) including an injector (12) for delivery of a fuel-gas mixture to a combustion chamber (60) of the engine (20). The engine (20) includes a gas supply system (11;13) pressurized at start-up through a pump-up sequence to a desired pressure for injection of fuel to the engine (20). In the pump-up sequence, the injector (12) is opened allowing pressurized gas to flow from the combustion chamber (60) through the injector (12) and into the gas supply system (11;13). This pressurizes the gas supply system (11;13) when pressure in the combustion chamber (60) is higher than the pressure in the gas supply system (11;13).

Abstract: A fuel injection system incorporates a plurality of fuel injection arrangements, wherein each fuel injection is associated with a particular cylinder of the engine. Each of the fuel injection arrangements comprises a fluid passageway in which fuel and air are combined prior to injection into a combustion chamber of the cylinder. A valve is moveable with respect to an injection port to allow the pressurized fuel/air mixture to flow from the fluid passageway into the combustion chamber. A fuel injector is used to inject liquid fuel into the fluid passageway to be combined with pressurized air within the passageway. The system has a common air rail and a common fuel rail which are each connected to a plurality of the fuel injection arrangements. Upward movement of a piston within a cylinder is used to pressurize the air within the common air rail. All of the fuel injection arrangements can be used to contribute pressurized air to the common air rail.
