    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.
