摘要:
An engine employs a dual mode combustion process including a first combustion mode for light loads utilizing premixed charge forced auto ignition (PCFA) wherein a pulse jet of reacting fuel mixture from a prechamber mixes with an ultra dilute premixed fuel-air charge in a main chamber, causing rapidly expanding combustion that ignites the remaining ultra dilute mixture by compression ignition. This improves efficiency, allows combustion phasing control and reduced NOx emissions. For higher speeds and loads, a conventional second combustion mode is utilized wherein a strong premixed mixture is ignited conventionally with spark ignition and/or pulse jet ignition. Cylinder pressures which would result from compression ignition at the higher speeds and loads are thus reduced providing overall engine operation with reduced emissions, improved fuel economy, and reduced noise through improved control of the combustion process.
