  • Patent number: 12158116
    Abstract: Operating an engine includes injecting one or more early pilot shots of a liquid fuel containing methanol (MeOH) into a cylinder in an engine, and moving a piston in the cylinder from a bottom-dead center position toward a top-dead center position. Operating an engine further includes forming hydrogen peroxide (H2O2) in the cylinder from the MeOH of the early pilot shots, injecting a main shot of a liquid fuel into the cylinder, and hastening combustion of the liquid fuel of the main shot in the cylinder via hydroxyl (OH) radicals formed from dissociation of the H2O2. Injection of the one or more early pilot shots at appropriate crank angle timing(s) associated with suitable temperature ranges may promote desired reaction pathways according to a medium temperature combustion regime.

  • Patent number: 11143137
    Abstract: Operating a direct-injection compression-ignition engine includes injecting early pilot shots of fuel, and controlling a cylinder temperature timing to combust the early pilot shots according to a combustion phasing that is based on the cylinder temperature timing. A main charge of the fuel is combusted based on the combustion of the early pilot shots. A combustion control unit is structured to command actuation of a fuel injector and a cylinder temperature controller to phase combustion of early pilot shots of the fuel, prior to a TDC position of a piston in an engine cycle. The cylinder temperature controller is a variable valve actuator or other apparatus controlling cylinder temperature in a manner decoupled from piston position.
