Thermal Efficiency is lower in Diesel Engine, because its overall efficiency is higher, its more heat is utilize in converting mechanical power.

Because in 2 stroke engine the 2 process suction and compression are completed in only 1 stroke so fuel can not efficiently burn.

So heat can not produce that much at that moment next expansion and exhaust stroke has done so heat is liberated, and T reduces, therefore, Thermal efficiency reduced.
