GENERAL KNOWLEDGE

Detailed explanation-1: -The engine of a car works by burning of fuel. It burns the fuel and produces mechanical energy which enables the vehicle to move. Hence, the engine converts chemical energy to mechanical energy.

Detailed explanation-2: -Kinetic energy inside the engine is transformed from chemical energy (fuel, air and spark plugs) to mechanical energy.

Detailed explanation-3: -A combustion engine is a complex machine that burns fuel to produce thermal energy and then uses the energy to do work. In a car, the engine does the work of providing kinetic energy that turns the wheels. The combustion engine in a car is a type of engine called an internal combustion engine.
