Hydrocarbon emissions in a homogeneous direct-injection spark engine : gasoline and gasohol
… charge motion control valve, spark timing and rail pressure were tested through holding all other variables constant and sweeping through different injection timing to observe the effect on emissions and power output. A new fuel system was designed to allow for the quick testing of different …

Understanding the development of a reacting fuel jet inside an automotive-size diesel engine using optical and laser-based diagnostics
… piston bowl and cylinder liner. Using the common-rail fuel injection system of the engine, the fuel injection was executed for long duration, creating negative ignition dwell conditions in which the start of combustion occurs before the end of injection. A single-hole nozzle was used to isolate …

Investigation of cluster nozzle concepts for direct injection diesel engines
… orifice diameter, multiple injections and high pressure injection are avenues of rigorous research with the injection systems evolving rapidly. Fuel consumption and emission of PM are improved by using high pressure injection due to better air-fuel mixing while there are still problems with NOx …
