    摘要: A turbocharger (32) creates intake manifold boost for a diesel engine (10). At times, exhaust valve opening is increasingly retarded in relation to the engine operating cycle to cause the turbocharger to increase boost, engine fueling is also increased in relation to the increased boost, and in response to any incipient surging of the compressor resulting from such increasingly retarded exhaust valve opening and such increased engine fueling, compressed charge air is bled from the intake manifold to counter the incipient surging and thereby avoid any significant turbocharger surge.

    摘要: An internal combustion engine (10) has an intake system (12) that includes a turbocharger (32). An engine control (30) processes data for controlling the opening of the exhaust valves (24) and for controlling fueling of the engine in relation to the engine operating cycle. In response to initiation of engine acceleration, the control increasingly retards exhaust valve opening in relation to the engine operating cycle to cause the turbocharger to increase pressure in the intake manifold (14) and increases engine fueling in relation to the increased pressure in the intake manifold.

    摘要: A turbocharger (32) creates intake manifold boost for a diesel engine (10) that has a variable valve actuation mechanism. At times, exhaust valve opening (EVO) is increasingly retarded in relation to the engine operating cycle (56) to cause the turbocharger to increase boost, engine fueling is also increased in relation to the increased boost (58), and in response to any incipient surging of the compressor resulting from such increasingly retarded exhaust valve opening and such increased engine fueling, compressed charge air is bled from the intake manifold through the combustion chambers to the exhaust system (62) to counter the incipient surging and thereby avoid any significant turbocharger surge. The bleeding is accomplished by keeping the exhaust valves (24) slightly open beyond the time that they would otherwise close.

    摘要: A control (30) embodies an operating strategy (50) to facilitate engine cranking and starting via control of timing of cylinder intake (18) and exhaust (24) valve opening using a variable valve actuation mechanism (26). Prior to fueling any cylinder (16), the engine (10) is cranked while the variable valve actuation mechanism causes pistons (32) to operate at an initial effective compression ratio for initial cranking that is less than an effective compression ratio for running when the engine is eventually fueled and runs under its own power. Thereafter, and still before fueling, they are caused to operate at an increased effective compression ratio, and still thereafter, a portion of their charges are drawn from the exhaust system (22). As the engine warms up, valve timing is adjusted.

    摘要: An engine exhaust aftertreatment system including a mixer disposed in the exhaust stream. The mixer includes a mesh section having a mesh of wires and may include a baffle section having a deflector that redirects a direction of flow of the exhaust stream. The mesh section may not extend across an entire width of an exhaust conduit containing the exhaust stream. The mesh section may also be sized and located to intersect the reductant introduced by the injector.
