  • DIESEL ENGINE PARTICULATE FILTER REGENERATION SYSTEM AND METHODS
    Publication number: 20190078523
    Abstract: Methods and systems for supplying post injection fuel to a two stroke diesel engine are described. In one example, post injection fuel timing is adjusted responsive to an amount of internal residual combustion products in a cylinder so that less post injected fuel may be trapped in the cylinder for a subsequent cycle of the cylinder. The start of post injection fuel timing and the amount of post injection fuel may be adjusted responsive to internal residual in the cylinder.

  • CONTROLLED AIR ENTRAINMENT PASSAGE FOR DIESEL ENGINES
    Publication number: 20190003371
    Abstract: Systems are provided for cooling combustion chamber gasses and increasing an amount of air entrained in an injected fuel spray.

  • Diesel engine cold starting system and methods
    Patent number: 10138833
    Abstract: Methods and systems for supplying starting a diesel engine that does not include glow plugs are described. In one example, a flow through a cylinder is limited during engine cranking to heat charge in a cylinder. In another example, a compressor is activated and air supplied to engine cylinders is heated via the engine and the compressor and recirculated to improve engine starting.

  • METHOD OF FUEL INJECTION CONTROL IN DIESEL ENGINES
    Publication number: 20180328307
    Abstract: Methods and systems are provided for adjusting fuel injections provided to a cylinder when a fuel rail pressure deviation from a threshold pressure is detected. In one example, a method may include reducing a total number of pilot and/or main fuel injections provided to a cylinder in a given cylinder cycle in response to a reduction of pressure in a fuel rail. In this way, the threshold rail pressure may be maintained, reducing the likelihood the engine will be derated.

  • Method of fuel injection control
    Patent number: 9903307
    Abstract: Methods and systems are provided for improving engine performance at high load conditions with reduced combustion phasing while maintaining in-cylinder peak pressures within limits. Following a pilot fuel injection, a main fuel injection is split into multiple smaller injections, the smaller injections spread around a timing of the main fuel injection so that peak cylinder pressures for each injection are within cylinder pressure limits. In this way, more enthalpy is created for expediting warming of exhaust catalysts.
