| 20110265456 | Diesel Engine and Method for Flexible Passive Regeneration of Exhaust After-Treatment Devices - 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. The engine may switch between cycles by using a cam follower with lost motion device capability, an electrical actuator, or any other selectively actuable valve actuator to prevent opening of the intake and exhaust valves during regeneration. | 11-03-2011 |

The exhaust treatment system may also have a fluid handling component located upstream of the power source to vary an amount of oxygen in the flow of exhaust, and a controller in communication with the regeneration device and the fluid handling component. The controller may determine a need for filter regeneration, and determine an adjustment to the fluid handling component required to provide sufficient oxygen in the exhaust flow for filter regeneration. The controller may further determine an effect the adjustment will have on operation of the power source, and determine an correction for the power source to account for the effect.
