The efficiency of a heat engine is affected by the amount of working gas it contains. A larger amount of working gas can lead to higher efficiency because it allows for more energy to be converted into useful work. Conversely, a smaller amount of working gas may result in lower efficiency as there is less gas available to transfer heat and produce work.

How to calculate the efficiency of a heat engine?
To calculate the efficiency of a heat engine, you can use the formula: Efficiency (Work output / Heat input) x 100. This formula compares the amount of useful work produced by the engine to the amount of heat energy it takes in. The efficiency is expressed as a percentage, with higher percentages indicating a more efficient engine.
Which is an impossible value of efficiency for a heat engine?
100% efficiency is impossible for a heat engine working between two reservoirs at different temperatures according to the second law of thermodynamics.
The amount of work done by heat engine equals the amount of what?
The amount of work done by a heat engine equals the difference between the heat input and the heat output of the engine. This is known as the heat engine's thermal efficiency.
What is the Otto cycle efficiency formula and how can it be used to calculate the efficiency of an engine?
The Otto cycle efficiency formula is given by: Efficiency 1 - (1 / compression ratio)(-1), where is the specific heat ratio of the working fluid. This formula can be used to calculate the efficiency of an engine by plugging in the compression ratio and specific heat ratio values. The higher the efficiency value, the more effectively the engine converts fuel into useful work.
How does heavy acceleration affect a vehicle's fuel efficiency and overall performance?
Heavy acceleration can decrease a vehicle's fuel efficiency by using more fuel in a shorter amount of time. It can also strain the engine and other components, potentially leading to decreased overall performance and increased wear and tear on the vehicle.
Does cutoff ratio affect the engine efficiency?
yes
Does the thermostat affect gas mileage?
Yes. Your engine will get the best mileage at full operating temperature. If the thermostat is removed or not working properly causing the engine to become too hot or not hot enough it will affect the operating efficiency or your engine which will decrease your gas mileage.

The amount of work you get from an engine divided by the energy you put into it?
Efficiency
How does compression ratio affect engine efficiency and performance?
Engine efficiency is increased though compression ratio by allowing a more thermodynamic energy to be converted into mechanical energy. Energy transfer is the key to efficiency.

Diesel engine loss of rpm under load?
yes because load affect the efficiency of engine , it can be improved by increasing the supply of oil in governer.
What happens when your oxygen sensor is not working?
If your oxygen sensor stops working the fuel (gasoline) and air mixture will be incorrect. Usually this means your fuel efficiency will decrease -- that is, the engine will burn more gasoline than necessary. It's possible however, if it begins to run too lean (not enough gasoline for the amount of air) it can damage the engine. But, this is unlikely.
Why diesel engine has volumetric efficiency greater than gasoline engine?
In diesel engine the air is only compressed in compression stroke and then diesel is entered .......so only small amount of fuel is consumed then petrol engine which take lot amount of fuel.......
How does heavy acceleration affect a vehicle's fuel efficiency and overall performance?
Heavy acceleration can decrease a vehicle's fuel efficiency by using more fuel in a shorter amount of time. It can also strain the engine and other components, potentially leading to decreased overall performance and increased wear and tear on the vehicle.
