Abstract: A fuel supply system for a reciprocating-piston engine includes a storage tank; a wall of the storage tank defining a first aperture and a second aperture therethrough; a first fuel injector fluidly coupled with the first aperture of the storage tank via a pressure control module and a first fuel injector supply conduit; a pump fluidly coupled with the second aperture of the storage tank; and a second fuel injector fluidly coupled with an outlet port of the pump via a second fuel injector supply conduit. The pressure control module is configured to maintain a pressure in the first fuel injector supply conduit within a pressure range that includes a pressure value that is less than a pressure inside the storage tank. The pump is configured to maintain a pressure inside the second fuel injector supply conduit that is greater than the pressure inside the first fuel injector supply conduit.

Abstract: Components for reducing oil sticking on surfaces of an internal combustion engine are disclosed. The engine may include an engine block with a piston cylinder, a piston moveable in reciprocal motion within the piston cylinder, and a cylinder head mounted on the engine block. The engine block, the cylinder head, and the piston may define a combustion chamber. The engine may include an intake conduit mounted to the cylinder head, an intake valve port defined by the cylinder head, and an intake valve mounted in reciprocally movable fashion to the cylinder head for placing the intake valve port in fluid communication with the combustion chamber. The engine may include a first oleophobic coating provided on portions of the intake valve, and a valve seat insert secured to the cylinder head. The valve seat insert may define an oil passage in fluid communication with the intake valve port.

Abstract: An exhaust system for an internal combustion engine includes an EGR cooler having a heat exchange surface exposed to a flow of exhaust, and a second heat exchange surface. A coolant heat exchanger is fluidly connected to a coolant outlet of the EGR cooler and a coolant pump is fluidly connected to a coolant inlet of the EGR cooler. A condensate collector collects condensate from exhaust, and a condensate pump pumps condensate from the condensate collector to a sprayer to spray condensate onto the second heat exchange surface to vaporize the condensate for discharging out through an outgoing exhaust conduit of the exhaust system.

Abstract: Operating a gaseous fuel engine includes injecting a pilot charge directly into a combustion chamber in an engine, and igniting one spray plume of the pilot charge. A flame front is propagated to other pilot spray plumes to produce an ignition flame for igniting later injected main charge spray plumes. Injection of the pilot and main charges is by way of the same fuel injection orifices.

Abstract: A NOx control system includes a lean NOx catalyst and an alcohol generator. The lean NOx catalyst includes a substrate and a hydrocarbon selective catalytic reduction (HC-SCR) catalyst disposed on the substrate. The HC-SCR catalyst catalyzes a reduction of NOx with an alcohol. The alcohol generator generates the alcohol.
