    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： A combustion chamber assembly for use in a diesel engine includes a combustion chamber being defined in a crown of a piston, the piston having a central axis, the combustion chamber having a center portion being elevated relative to a bottom plane of the combustion chamber. The center portion is defined in part by a portion of a sphere, the sphere having a radius, the origin of the radius lying on the combustion chamber central axis. The combustion chamber further has an outer margin, the outer margin being defined in part by a portion of a sphere, the sphere having a radius, the origin of the radius lying on the combustion chamber central axis and being greater than the center portion radius. The spherical center portion and the spherical outer margin are connected by an annular surface. And, the combustion chamber has a plurality of curved surfaces having smooth tangential transitions between adjacent smooth surfaces, the smooth surfaces including the spherical center portion and the spherical outer margin in combination with the annular surface. A piston incorporating the aforementioned combustion chamber and a method of forming the combustion chamber are further included.

    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.
