摘要： An exhaust gas recirculation (EGR) system for a turbo-charged internal combustion engine is provided. The EGR system includes a recirculation conduit for recirculating a volume of exhaust gas from the exhaust manifold to the intake manifold; a bypass conduit for diverting a flow of intake air around the engine; and an EGR cooler disposed in operative association with the recirculation conduit and the bypass conduit and adapted for cooling the volume of recirculated exhaust gas in the recirculation conduit. The exhaust gas recirculation cooler or heat exchanger is also adapted for concurrently heating the intake air in the bypass conduit. The heated intake air together with the exhaust gas remaining in the exhaust manifold is used to drive the turbocharger. The disclosed embodiment of the exhaust gas recirculation system also includes an air-to-air after-cooler used to cool the compressed intake air. The cool, compressed air is then diverted to the exhaust gas recirculation cooler to cool the recirculated exhaust gas.

The exhaust gas recirculation system has an adjustable flow and is operable to supply exhaust gas to at least one engine cylinder. The engine further includes means for determining a value indicative of a charge density of a combustion mixture that includes gaseous fuel, air and exhaust gas supplied to the at least one cylinder, and adjusting a flow quantity through the exhaust gas recirculation system based at least in part on the value.

摘要： An exhaust particulate filter for an engine system includes an array of filter cartridges positioned within a shell, each of the cartridges having an electrically powered heating element coupled therewith. Exhaust gases may be distributed among the cartridges according to a single distribution pattern, and the filter can be regenerated without diverting, dividing or bypassing exhaust gases from the filter. The filter cartridges may be cylindrical or wedge-shaped, or of a variety of other configurations. Regeneration may take place according to a non-axial regeneration propagation profile. Other aspects include feedback control and feedforward control of regeneration based on sensing an electrical resistance property of each of the electrically powered heating elements.

摘要： A free piston internal combustion engine includes a housing with a combustion cylinder and a hydraulic cylinder. A piston includes a piston head reciprocally disposed within the combustion cylinder and movable during a compression stroke to a top dead center position and during a return stroke to a BDC position. A plunger head is reciprocally disposed within the hydraulic cylinder. A plunger rod interconnects and is rigidly affixed to each of the piston head and the plunger head. The plunger head and the hydraulic cylinder define a variable volume pressure chamber on a side of the plunger head generally opposite the plunger rod. At least one valve interconnects a hydraulic accumulator with the pressure chamber during a portion of the compression stroke to act on the plunger head and thereby move the piston head toward the top dead center position, and interconnects the hydraulic accumulator with the pressure chamber during the return stroke to pressurize the hydraulic accumulator during movement of the piston head toward the BDC position.

摘要： A method of operating a free piston engine of the present invention, includes a housing with a combustion cylinder and a second cylinder. A piston includes a piston head reciprocally disposed within the combustion cylinder, a second head reciprocally disposed within the second cylinder, and a plunger rod interconnecting the piston head with the second head. A supply of hydraulic fluid is pulsed from a high pressure hydraulic accumulator into a pressure chamber in the second cylinder adjacent the second head during a beginning portion of a compression stroke to cause the piston head to move toward a top dead center position. The high pressure hydraulic accumulator is decoupled from the pressure chamber after the pulsing step. A low pressure hydraulic accumulator is coupled with the pressure chamber during a remaining portion of the compression stroke. The high pressure hydraulic accumulator is coupled with the pressure chamber when the piston head is traveling toward a BDC position during a return stroke. A sensor senses a position of the piston which is at or near the BDC position and provides a corresponding signal. The coupling between the high pressure hydraulic accumulator and the pressure chamber is maintained for a period of time, dependent upon the sensor signal.
