The average exhaust temperature of a two-stroke/cycle diesel engine with a turbine-driven supercharger is lower than a similar four-stroke/cycle engine at equal loads because____.
A.
two-stroke/cycle diesel engines have a higher MEP than four-stroke/cycle diesel engine
B.
four-stroke/cycle diesel engine exhaust is cooled by scavenging air
C.
two-stroke/cycle diesel engines have a lower MEP than four-stroke/cycle diesel engines
D.
the opening of the two-stroke/cycle diesel exhaust ports or valves occurs much later than in four-stroke /cycle diesel engine
