The average exhaust temperature of a two-stroke/cycle diesel engine with a turbine- driven supercharger is lower than a similar four-stroke/cycle diesel engine at equal loads because __________. |
A) two-stroke/cycle diesel engines have a higher M.E.P. than four-stroke/cycle diesel engines |
B) four-stroke/cycle diesel engine exhaust is cooled by scavenging air |
C) two-stroke/cycle diesel engines have a lower M.E.P. 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 engines |
