    摘要: An internal combustion engine is configured to utilize a reactivity controlled compression ignition process and an exhaust gas recirculation (“EGR”) system. The EGR system directs a portion of the exhaust gasses from the exhaust system to the air intake system. The engine system is adapted to introduce a first fuel charge having a first reactivity to a combustion chamber at a first time during the intake-compression cycle of the engine. The engine system is also adapted to introduce a second fuel charge having a second reactivity at a second time during the intake-compression cycle to generate stratified regions of different reactivity in the combustion chamber. A controller operatively associated with the engine can monitor one or more operating parameters and can adjust either the EGR system and/or the second introduction of the second fuel charge based in part upon the operating parameter.

    摘要: 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.

    摘要: An internal combustion engine includes a first cylinder having an intake valve in fluid communication with an intake manifold, and a second cylinder having an exhaust valve in fluid communication with an exhaust manifold. A transfer passage fluidly connects the first cylinder with the second cylinder. A first fuel injector is configured to provide a first fuel to the first cylinder, and a second fuel injector is configured to provide a second fuel to the second cylinder. The first cylinder operates, at times, to push a first air/fuel mixture through the transfer passage into the second cylinder. The second fuel injector is configured to provide at least one fuel injection plume into the first air/fuel mixture.

    摘要: A control system for estimating the performance of a compressor is disclosed. The control system has a compressor fluidly connected to an inlet manifold of a power source. The control system also has a power source speed sensor to provide an indication of a rotational speed of the power source, an inlet pressure sensor to provide an indication of a pressure of a fluid within the inlet manifold, an inlet temperature sensor to provide an indication of a temperature of the fluid within the inlet manifold, an atmospheric pressure sensor to provide an indication of an atmospheric pressure, and a control module in communication with each of the sensors. The control module is configured to monitor an engine valve opening duration and an exhaust gas recirculation valve position, and estimate a compressor inlet pressure based on the provided indications, the monitored duration, and the monitored position.
