摘要： A method and apparatus for injecting fuel into a diesel engine combustion chamber is provided wherein a pre-pilot injection is injected sufficiently prior to critical mass conditions being achievable to permit vaporization and formation of a substantially homogenous mixture before a critical mass exists. Preferably, a pilot injection is injected after the pre-pilot injection but at or before a point wherein a critical mass based on the pre-pilot quantity. This will result in a reduced heat release rate will result in a slower, smoother and more controlled build up of pressure in a combustion chamber and thereby advantageously reduce combustion noise.

摘要： A turbocharger (32) creates intake manifold boost for a diesel engine (10). At times, exhaust valve opening is increasingly retarded in relation to the engine operating cycle to cause the turbocharger to increase boost, engine fueling is also increased in relation to the increased boost, and in response to any incipient surging of the compressor resulting from such increasingly retarded exhaust valve opening and such increased engine fueling, compressed charge air is bled from the intake manifold to counter the incipient surging and thereby avoid any significant turbocharger surge.

摘要： A control system (FIG. 4) for controlling regeneration of a DPF comprises a favorable-condition-based control section (52), a regular control section (54), and a regeneration termination control section (56). Section (54) initiates regeneration when the actual soot loading of the DPF becomes sufficiently large to mandate initiation of regeneration. Section (52) initiates regeneration when the actual soot loading reaches an amount less than the amount at which section (54) mandates regeneration, provided that selected engine operating conditions disclose conditions favorable for regeneration. Section (56) terminates regeneration when soot loading is reduced to some minimum amount or when conditions for continuing regeneration become unfavorable. By burning trapped soot during favorable conditions, the mandatory regeneration is postponed. This can lower the average amount of trapped soot in the CDPF, thereby lowering the average back-pressure on the engine.
摘要翻译：用于控制DPF再生的控制系统（图4）包括有利条件控制部分（52），常规控制部分（54）和再生终止控制部分（56）。当DPF的实际烟灰负荷变得足够大以确定再生的开始时，部分（54）开始再生。当实际的烟炱负荷达到小于部分（54）强制再生的量时，部分（52）启动再生，条件是所选择的发动机操作条件公开了有利于再生的条件。当烟灰负载减少到一定的最小量时，或当连续再生的条件变得不利时，部分（56）终止再生。通过在有利条件下燃烧捕获的烟灰，强制性再生被推迟。这可以降低CDPF中的平均烟灰量，从而降低发动机的平均背压。
