Abstract: A hydrogen-diesel dual-fuel engine that includes an engine block, where the engine block includes a cylinder outfitted with at least two hydrogen fuel injectors and a piston. The engine further includes an air-handling system that includes an intake manifold, an intake pipe, an exhaust pipe, a variable geometry turbocharger, and an exhaust gas recirculation system configured to recirculate exhaust gases from the exhaust pipe to the intake manifold. The engine further includes a two-step camshaft, where the two-step camshaft is configured with the air-handling system for exhaust re-breathing and late intake valve closing, and a port fuel injector system that provides hydrogen gas to the at least two hydrogen fuel injectors. The engine further includes a diesel injector, a common-rail fuel injection system, a plurality of sensors, and a controller configured to receive engine data from the plurality of sensors and to control operation of the hydrogen-diesel dual-fuel engine.

Abstract: A motor system includes an engine having one or more cylinders, an electronic control unit, an exhaust treatment system in fluid connection with and downstream of the one or more cylinders. The exhaust treatment system includes an exhaust line, a combustion zone downstream, a combustion ignition source in the combustion zone, a catalyst downstream of an in thermal communication with the combustion zone. A method of heating a catalyst during an engine cold start and a method of initiating regular operating conditions of an engine having one or more cylinders are also described.

Abstract: A prechamber device includes an enclosure body and a cap forming an enclosed volume. The enclosure body has an orifice at one end. A precombustion chamber is defined within the enclosed volume and is in fluid communication with the orifice. A valve plug is movable along an axial axis of the enclosure body to adjust a valve opening at the orifice to a range of positions from a fully open position to a closed position. An actuator is coupled to the cap and the valve plug and is controllable to displace the valve plug along the axial axis of the enclosure body. The prechamber device is operable to generate turbulent jets that are directed into a main combustion chamber of an engine cylinder through the valve opening. During an engine cycle, the valve opening is controlled between the range of positions based on detected engine speed and engine load.
