Question

In IC engine which energy converted in to mechanical energy

Answer 1

heat energy is converted into mechanical energy

Answer 2

In an IC engine, chemical energy is converted into mechanical energy.

• Internal combustion heat engines are devices that try to convert the enthalpy of combustion into directly usable mechanical energy, i.e. to convert the chemical energy of the fuel into practical power or driving force of drive.
• The thermal cycle determines how the heat of combustion is turned into electricity.
• The Otto and Diesel cycles have traditionally been employed in automobile vehicles.
• Fuels require acceptable physical and chemical qualities due to the physical parameters of the reaction mixture in each thermal cycle.
• For cycle diesel engines, the fuel must have a high viscosity and be quick to ignite when in contact with warm air.
• In the case of Otto-cycle fuels, strong volatility and the ability to resist compression without auto-ignition are necessary.
