Why turboprop engines are not preferred for higher speed?
Propellers lose efficiency at around 375 knots.
Which type engine offers the highest propulsive efficiency?
Electric engines typically offer the highest propulsive efficiency compared to other types of engines, such as internal combustion engines or gas turbines. This is because electric engines can convert a higher percentage of their energy input into useful work, resulting in better overall efficiency.
What is the efficiency of wankel engine when compared to conventional engine?
the efficiency of the wankel engines is 38 % as compared to the inline or v line engines which holds only 21%.... I don't know where that guy got that information from, but it's pretty wrong if he's talking about fuel efficiency. Wankel engines are quite poor in efficiency, but when compared to inline engines that offer the same performance (powerful V8s) they will have similar fuel efficiencies.
What is the efficiency of a gasoline engine?
Gasoline engines have a 30% efficiency, as compared to a Diesel engine having 40% efficiency. COOL HUH
What is the significance of the Carnot COP in the efficiency of heat engines?
The Carnot COP is significant in the efficiency of heat engines because it represents the maximum possible efficiency that a heat engine can achieve. It serves as a benchmark for comparing the performance of real-world heat engines, helping engineers to design more efficient systems.
Machine that transforms heat into mechanical energy?
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.

How theoretically can calculate volumetric efficiency in diesel engines?
1282kg/s
How much efficiency do you lose when using a home resistance heater?
You lose a lot of efficiency, since resistance heaters make heat off being inefficient.
What causes gears to lose some of their efficiency?
friction
What are the key differences between unleaded and diesel fuel, and how do these differences impact vehicle performance and efficiency?
Unleaded fuel is used in gasoline engines, while diesel fuel is used in diesel engines. The main difference is in their ignition process: gasoline engines use spark plugs to ignite the fuel, while diesel engines rely on compression to ignite the fuel. This difference affects performance and efficiency, as diesel engines typically have higher torque and better fuel efficiency compared to gasoline engines. Diesel fuel also has a higher energy density, which can result in better mileage for diesel vehicles. However, diesel engines tend to produce more emissions than gasoline engines.
Why are heat engines intentionally run at high operating temperatures?
better thermal efficiency.
How efficient is the combustion engine?
The efficiency of a internal combustion engine varies with size, speed range, compression ratio etc. Diesel engines use higher compression ratio and operate without throttle control, therefore their efficiency is higher than a equivalent Otto engine. Large marine (read ship engines) or stationary diesel engine: 50% Heavy duty diesel engines for marine, stationary and vehicle applications (trucks): 40% Light duty diesel engines (cars): 30-35% Gasoline engines: 20-25% + a few % for newer engines The numbers mentioned above are maximum efficiency, not pedal to the metal efficiency. Please note that the thermal efficiency of a engine will increase if the combustion chamber surface decrease(!). Higher revs leads to higher forces acting on the piston rings and therefore higher frictional losses, in other words: the mechanical efficiency decreases with increased speed.
