청구항

1. An engine operating method, comprising: operating a Miller cycle engine with fuel injected in an exhaust system of the Miller cycle engine at a location upstream of a turbine coupled to a crankshaft of the Miller cycle engine; andpassing exhaust gases from the Miller cycle engine through the turbine, where the turbine is coupled to the crankshaft via a transmission and where the turbine is coupled to the crankshaft via a turbine clutch; the method further comprising closing the turbine clutch in response to a temperature of an exhaust component exceed...
