What makes an engine faster?

Basically, the faster the crankshaft spins with the same amount of force, the more power an engine will make. A car with more hp than torque will always be quicker since this gives a car acceleration and speed. … The two will offer the same amount of speed, but the diesel will accelerate more quickly.

What makes an efficient fuel?

Other techniques for making cars fuel-efficient include making them lighter, with materials from high-strength steel through aluminum to carbon fiber, and reducing their wind resistance through painstaking attention to tiny details of the body shape that minimize aerodynamic drag.

Can a system ever be 100% efficient?

Explanation: No machine is free from the effects of gravity, and even with wonderful lubrication, friction always exists. The energy a machine produces is always less than the energy put into it (energy input). … That is why 100% efficiency in machines shall not be possible.

Is Carnot engine 100 efficient?

In order to achieve 100% efficiency (η=1), Q2 must be equal to 0 which means that all the heat form the source is converted to work. The temperature of sink means a negative temperature on the absolute scale at which the temperature is greater than unity.

Why is a perfect heat engine Impossible?

It is impossible to construct a perfect heat engine. … Since it absorbs heat, its entropy is increased. If it increases its entropy enough, it will ensure that the entire system has a net increase in entropy.
