摘要： A fluid pump includes a hollow housing, an electric motor having an armature with a commutator, a pump section rotationally coupled to the electric motor for receiving fuel at a relatively low pressure through a fuel inlet and pressurizing the fuel to a relatively high pressure, a motor brush is in electrical contact with the commutator and including a shunt wire extending therefrom, and an end cap that closes one end of the housing and defines a high pressure chamber with the housing. The end cap includes a hollow brush tower extending therefrom and defining a brush holder slidably receiving the motor brush therein such that the brush holder defines in part the high pressure chamber. The end cap also includes an aperture with the shunt wire extending therethrough such that the shunt wire is sealed with the aperture to prevent the fuel from passing therethrough.

摘要： A fuel pump assembly (30) for an internal combustion engine, the fuel pump assembly comprising a pump chamber (36) for fuel; a plunger (32) which is driven by means of a drive arrangement to cause pressurization of fuel within the pump chamber (36); and a first housing part (40) provided with a recess (38a, 38b) which defines the pump chamber (36) in an upper region (38a) thereof and which receives a second elongate housing part (44) in a lower region thereof, wherein the second housing part (44) defines a plunger bore (34) for receiving the plunger (32). The second housing part (44) projects from the recess (38a, 38b) so that a greater proportion of the second elongate housing part (44) extends from the recess (38a, 38b) than is received within the recess (38a, 38b).

摘要： A fuel injector (10) for a compression ignition internal combustion engine is described. The fuel injector (10) comprises a fuel injection valve having an injection valve member (14) moveable, in use, under the influence of fuel pressure within a control chamber (20) acting upon it, between a closed position and an open position. The fuel injector comprises a moveable plate (28) located inside the control chamber (20). The moveable plate (28) is configured to move into and out of contact with a sealing surface (34) of the control chamber (20). The moveable plate (28) includes an inlet orifice (38) and a spill orifice (40). The provision of inlet and spill orifices (38, 40) in the moveable plate allows both orifices to be made very small, resulting in a significant reduction in dynamic leakage. An embodiment of the invention is described in which the moveable plate (28) defines additional fluid channels (60a, 60b, 62a, 62) for high pressure fuel entering the control chamber (20) when the moveable plate (28) is moved out of sealing contact with the sealing surface (34) of the control chamber (20). The additional flow paths allow high pressure fuel to enter the control chamber (20) bypassing the inlet orifice, resulting in a rapid termination of an injection event.

摘要： A method for fault identification of gas sensors exposed to a gas mixture is disclosed for gas sensors having an output that depends on concentrations of two gas species in the gas mixture. The method includes receiving output signals from two such sensors, processing the output signals in a controller that implements a model of the sensors so as to identify a fault in the first gas sensor or the second gas sensor; and providing an indication of any identified faults.
