The efficiency of a Carnot engine is theoretically always greater than that of an actual engine. The fact that it is impossible to build a thermodynamically reversable engine, which is one of the variables necessary to calculate its superiority to a real heat engine, makes the theorum practical for assessing a real heat engines efficiency only.

The answer is 38.
The purpose of adding oil to a car i to lubricate the engine. if the engine is not lubricated there will be much more friction between gears and friction generates heat. because energy is needed to create heat that energy is taken away from the energy that would be propelling the car forward. this causes the efficiency yo drop.
It is not a good efficiency engine.
Carnot's heat engine has more efficiency then the other heat engine but it is assumption. Is is not real. RGUKT IIIT NUZVID: N091528
Thermal efficiency is the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
Efficiency would increase.
A ficticious heat engine that works at the maximum theoretical efficiency is called a Carnot engine. Real engines, that obviously work at a lesser efficiency, include the combustion engines found in cars.A ficticious heat engine that works at the maximum theoretical efficiency is called a Carnot engine.

As a "heat engine", a car engine must rid itself of heat to continue. Efficiency of the heat engine depends on the difference in temperature; therefore, as the temperature outside reaches the temperature inside, the engine stops.
If it is burned - which is the way such fuels are usually used - the energy efficiency is the energy efficiency of a heat engine. The theoretical maximum efficiency is the Carnot efficiency; the real efficiency will usually be considerably less than that.
