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 __________.

Correct Answer: Option C — two-stroke/cycle diesel engines have a lower M.E.P. than four-stroke/cycle diesel engines

Two-stroke cycle diesel engines generally operate with lower mean effective pressures compared to four-stroke designs of similar output under specific rating conditions, resulting in lower overall exhaust gas temperatures entering the turbine.
