Publication number: 20130298888Abstract: An internal combustion engine includes a cylinder that is connectable to an intake manifold through an intake valve, to an exhaust manifold through an exhaust valve, and to a transfer manifold through transfer and combustion valves. A fuel injector associated with the cylinder is adapted to provide fuel to the cylinder. During operation, the cylinder performs an intake stroke, followed by a compression stroke. A compressed charge from the cylinder passes to and is collected in the transfer manifold through the transfer valve. The cylinder is filled by a compressed charge from the transfer manifold through the combustion valve at the same time as the fuel injector provides fuel. The cylinder then undergoes combustion and exhaust strokes. In this way, cylinder operation alternates between combustor and compressor split combustion modes.Type: ApplicationFiled: May 8, 2012Publication date: November 14, 2013Applicant: CATERPILLAR INC.Inventor: Scott B.

Publication number: 20110265456Abstract: A diesel engine and method for operating a diesel engine with exhaust after-treatment device regeneration capability are disclosed. The diesel engine may employ an exhaust after-treatment device such as a diesel particular filter to remove soot from the combustion gases exhausted by the engine. In order to regenerate the exhaust after-treatment device, the temperature of the exhaust gases is raised sufficiently to do so. The temperature of the exhaust gases is raised to such a level by employing multiple compression and expansion strokes of the piston in certain engine cycles, with a combustion event associated with each pair of compression and expansion strokes. The engine may operate in a four stroke, one combustion cycle during conventional power operation, and switch to an enhanced combustion cycle during regeneration. The enhanced combustion cycle may include eight strokes such as one intake stroke, three compression strokes, three expansion strokes, and one exhaust stroke, with three combustion events.Type: ApplicationFiled: April 29, 2010Publication date: November 3, 2011Applicant: CATERPILLAR, INC.Inventors: Scott B.
