The main useful energy change in a petrol engine is the conversion of chemical energy from fuel into mechanical energy. During combustion, the chemical energy stored in petrol is transformed into heat energy, which then expands gases that drive the pistons. This mechanical energy ultimately powers the vehicle's movement. Efficient energy conversion is crucial for optimal engine performance.
What else can I help you with?
Is petrol used in a car engine a harmful or useful?
Short answer Yes. Petrol is useful for running a engine, and extremely dangerous if misused.
Petrol used in a car engine useful or harmful?
The engine will not run without a supply of petrol so you would think it is useful.
When petrol used in a car engine harmful or useful?
The engine will not run without a supply of petrol so you would think it is useful.
Is it useful or harmful reaction when Petrol is used in car engine?
Petrol is British name for Gasoline
Is there an energy advantage if diesel contains 17 percent more chemical potential energy than petrol?
Yes, the energy output of an engine is governed by the chemical potential energy of the fuels. Assuming that the extra potential energy could be turned into useful work, there would be an energy advantage of diesel over petrol.
Is it an useful or harmful reaction when Petrol is used in car engine?
Well petrol is short for petroleum which is Gasoline! so unless your car runs on anything thing else i'd say its usefuL!
Petrol used in car engine useful or harmful?
the carbon dioxide which comes from the burned petrol of cars is definitely harmful if you directly breathe it in, but not really harmful otherwise
An airplane changes energy into different forms The total amount of energy does not?

When people say energy is lost what do they mean?
The energy in a closed system is constant, which is the principle of Conservation of Energy, but in machines the amount of useful energy coming out is less than the amount going in. This is explained by lost energy. In a petrol engine the lost energy comes out in the form of heat because the engine block is hot, which happens because of friction in the bearings but also because the gas in the cylinder has to be at a high temperature and pressure.
How is fossils useful?
they are useful for alot of things like petrol
What is the energy in a chemical or physical change that is available to do useful work?
Free energy
Petrol used in a car engine is it useful or harmful?
Used properly where it was intended to be used for gasoline powered engines is useful. Breathing gasoline vapors to get high is harmful not mention stupid.
