It varies from zero (idling) to a max of 38 % ... but the average is about 20 %.
Such an engine is used mainly to convert the chemical energy of the petrol into kinetic energy for various applications. And indeed it does that, but it also converts a considerable amount of the chemical energy into heat, which is generally of no use at all and must be vented into the passing air in order to avoid melting the engine.
A petrol chainsaw converts chemical energy stored in gasoline into mechanical energy through combustion.
kinetic
No, petrol is a form of stored chemical energy. When burned, it releases heat energy which can be used to perform work.
Inputs -> OutputsChemical Kinetic energy (movement)energy Sound energy ( from horn and engine)(from fuel) Light energy ( from front and rear lights)
chemical energy and its converted to kinetic energy
Chemical energy from petrol which is converted to heat then to kinetic energy and then converted to rotational energy.
Chemical energy from petrol which is converted to heat then to kinetic energy and then converted to rotational energy.
Chemical energy, Petrol is made of crude oil, it can be used to make kinetic,heat,light,sound, from burning it
A car converts the chemical energy in petrol to kinetic energy which makes it move along. A fan converts electrical energy into kinetic energy to make the blades turn.
Chemical potential energy is stored in petrol. When petrol is burnt, this chemical energy is converted into heat, light, and mechanical energy to power vehicles.
Even the most efficient petrol engines are quite inefficient at changing the chemical energy in the fuel to kinetic energy. Most becomes heat and some turns into sound. Somewhere in the region of 25% becomes turning force into the transmission.
Chemical energy of the petrol transformed into sound and heat, but mostly kinetic energy. Friction of tires on road, air resistance etc.

And indeed it does that, but it also converts a considerable amount of the chemical energy into heat, which is generally of no use at all and must be vented into the passing air in order to avoid melting the engine.
The energy stored in chemical fuels such as petrol is called chemical potential energy. This energy is released when the fuel undergoes a chemical reaction, such as combustion, which can be harnessed to do work.
