    摘要: A method using concurrently and simultaneously certain control factors for in-cylinder combustion, at least two of such factors being at levels never tried before by the prior art. The combination of control factors comprises: (i) high pressure charging of supply air for enhanced excess oxygen; (ii) advanced techniques for improved in-cylinder mixing of fuel and air (i.e., high swirl, reentraining piston bowl configuration, high compression ratio); (iii) high pressure injection of diesel fuel at levels of 1.1 X 10⁵ - 1.5 X 10⁵ kPa (16-­22 x 10³ psi); (iv) smaller fuel nozzle ports for creating finer droplet size; (v) retardation of fuel injection from TDC by 2-5/; and (vi) limitation of the ingress of lubricating oil into the combustion chamber by use of noncompressed cylinder sleeves to enhance piston to bore concentricity and preferably by other augmenting limits.

    摘要: The invention discloses internal combustion engines, particularly compression ignition engines such as diesel engines, having reduced nitrogen oxide emissions with concurrent reductions in particulate emissions. The invention provides a catalyst impregnated prechamber insert (30) which operates in the fuel rich environments of internal combustion engines to reduce nitrous oxides.
