  • Methods and system for adjusting camshafts
    Patent number: 10472999
    Abstract: Systems and methods for correcting an engine intake camshaft position and an engine exhaust camshaft position for a variable valve timing engine are described. In one example, intake manifold pressure of an engine is sampled while a motor/generator rotates the engine at a predetermined speed without fuel being supplied to the engine. A camshaft angle where minimum intake manifold pressure is observed is a basis for correcting camshaft position.

  • Method and system for engine cold-start control
    Patent number: 10100767
    Abstract: Methods and systems are provided for improving engine start roughness. In one example, a method for reducing engine start NVH includes operating the engine with a split fuel injection while advancing injection timing as engine coolant temperature increases. The method allows for a smoother engine start while also reducing false misfire incidences.

  • Method and system for supplying fuel to an engine
    Patent number: 9732695
    Abstract: Methods and systems are presented for adjusting an amount of fuel supplied to an engine via port and direct fuel injectors during transient engine operating conditions where the fuel injection amount is adjusted responsive to the transient engine operating conditions. In one example, a fuel injection amount is adjusted based on a time constant for a filter that is based on a direct fuel injection fuel fraction.

  • Systems and methods for improving engine emissions during starting
    Patent number: 9644559
    Abstract: Systems and methods for improving emissions of an internal combustion engine are presented. In one example, engine crankshaft acceleration is a basis for estimating engine air-fuel ratio during engine starting when output of an oxygen sensor may be unavailable. An actual engine air-fuel ratio may be adjusted in response to the estimated engine air-fuel ratio.

  • System and method for reducing engine oil dilution
    Patent number: 9470173
    Abstract: Methods and systems are provided for modeling an oil dilution qualitative indicator based on an integrated difference between a commanded air-to-fuel ratio and an engine air-to-fuel ratio as determined via an oxygen sensor, cumulative cold engine temperature operating duration, and fuel injection characteristics (timing, duration, number of injections) allowing fuel injection timing modifications that minimize oil dilution when the oil dilution qualitative indicator is greater than a threshold level.

  • Vapor recovery system
    Patent number: 5970957
    Abstract: A fuel vapor recovery system for a direct injection internal combustion engine operating in both stratified and homogenous modes includes using fuel vapor with air assisted injectors. A compressor compresses a controlled mixture of fresh air and fuel vapor which is then delivered to the air supply of air assisted injectors, allowing fuel vapors to be purged from the vapor recovery system during all engine operating modes.
