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.
摘要翻译：发动机采用双模式燃烧过程，其包括利用预混合充气强制自动点火（PCFA）的轻负载的第一燃烧模式，其中来自预燃室的燃料混合物的脉冲射流与主室中的超稀混合燃料 - 空气装料混合，引起快速膨胀的燃烧，通过压缩点火点燃剩余的超稀释混合物。这提高了效率，允许燃烧定相控制和减少NOx排放。对于更高的速度和负载，使用常规的第二燃烧模式，其中常规地用火花点火和/或脉冲喷射点火点燃强预混混合物。因此，在较高速度和负载下由压缩点火引起的气缸压力因此减少，通过改进对燃烧过程的控制，可以减少排放，提高燃油经济性，降低噪音。
