摘要： A system and method for controlling combustion in a direct injection spark ignition internal combustion engine inject fuel directly into a combustion chamber in a wide-angle, hollow-cone spray to form a vortex that draws fuel vapor out of the spray to form a combustible fuel-air mixture at a spark location outside the hollow-cone spray. Various piston combustion bowl configurations further enhance the stability of the vortex and reduce fuel impingement on the piston surface while providing a desired compression ratio. Cylinder airflow is controlled to produce substantial swirl flow resulting in a more compact fuel cloud around the spark location to reduce over-mixing and improve robustness to cycle-to-cycle variation in the mixing process.

摘要： A system and method for operating an internal combustion engine include injecting fuel through a plurality of fuel jets of a fuel injector directly into a corresponding cylinder with at least a first plurality jets oriented to primarily support operation in a stratified mode and a second plurality of jets oriented to primarily support operation in a homogeneous mode. The first plurality of jets is oriented to spray fuel generally downward toward the piston bowl and the second plurality of jets is oriented to spray fuel generally across the cylinder toward the exhaust valves. The spray jets reduce or eliminate valve, liner, and piston wetting while providing good mixing in homogeneous mode and good combustion stability for light stratified charge during cold starts to achieve desired targets for feedgas emissions and combustion efficiency.
