Abstract: EGR induction supercharged or turbocharged internal combustion engine (1) having EGR and EGR cooling in which EGR cooling is obtained through jacket water coolers and/or an air-to-air aftercooler. EGR induction is obtained via either low pressure (ambient) induction to the system intake, or via venturi (15) or passive pump induction into the pressurized intake. Bypassing of the EGR cooler (19) is used to reduce condensation and fouling in the EGR cooler and to provide warmer air to reduce light load and cold ambient hydrocarbon production. A passive or catalyzed particulate trap (9) and crankshaft driven supercharger boosting system (8) are provided to address engine response deterioration and particulate increase problems associated with EGR.

Abstract: An improved high pressure fuel injector (10') for internal combustion engines in which problems of hysteresis delays and fuel leakage at the commencement of the metering process can be avoided without affecting the ability to precisely control the fuel supply pressure by the provision of a way for the metering and injection plunger (26) to be acted upon only by the pressure of the incoming fuel supply. An improved metering and injection plunger spring arrangement (68, Sd) provides a valving of the drain path (44) that prevents leakage through drain passages (44, 66) and/or about the metering and injection plunger (26) during the fuel metering and injection phases. Also, a double check valve arrangement (34, 38) is incorporated into the plunger seat disc (6) to minimize the possibility of back-flow leakage of fuel during injection of the fuel from the metering and injection chamber (M).

Abstract: A variable displacement high pressure pump having a plurality of high pressure pumping units which receive fuel from a low pressure fuel pump. A rotary cam-driven roller tappet, for producing pumping displacement of the pumping plunger of a respective pumping element, is connected to the pumping plunger by a separated link in a manner permitting the pumping plunger to float relative to the roller tappet during at least a portion of each pumping cycle. As a result, the capacity of the pumping chamber can be limited to an extent that is less than the full stroke achievable by the pumping plunger being retracted to the maximum extent which is permitted by the driving cam. In this way, the quantity of fuel to be pressurized and injected into the common rail does not have to be determined by a cutting-off of a spilling flow of excess metered fuel during the compression stroke of the pumping plunger, so that a low pressure solenoid valve can be used, in the case of time-stroke and time-pressure metering, and no solenoid is required to control metering in the case of pressure-time metering.

Abstract: Cast iron gears, such as those used as cam gears on engines and as used for fuel injection gear pumps, which have a hub (2) and a rim (3) that are thick in comparison to the relatively thin web (5) used to interconnect the hub (2) with the rim (3) and a process by which such iron gears can be cast, especially in a vertical orientation. To eliminate porosity problems, single flow channel of substantial thickness is incorporated into the mold cavity which forms a flow rib (10) that runs radially between the hub (2) and rim (3) of the gear (1) being formed. To compensate for both the added weight of the rib (10) that is produced on the web (5) of the resultant gear (1), as well as to counterbalance the effect caused by the presence of a single rib (10), at least one opening (12) is formed in the web (5) at each side of the rib (10).

Abstract: A replaceable filter assembly (10) for fluids in which the filter has a shell formed from an injection molded threaded end (12) and an integral blow molded closed end (14) to form a unitary shell. A seal such as a flange (20) is provided adjacent to the threaded end so that a pressure seal can be maintained. A filter medium (30) is supported within the shell so as to direct fluid (30) flow through it to remove contaminants. The shell can be formed from plastic materials such a polyester terepthalate (PET), polyether sulfone (PES), and polyether urethane (PEU). This construction enables an inexpensive filter assembly and, with transparent plastic materials, an indication of the contaminant removal activity within the filter.
