This is a transparent car with an engine in a laboratory.
The engine is the heart of the car. It’s a complex machine that converts heat from burning gas into the force that turns the road wheels. The chain of reactions which achieve that objective is set in motion by a spark, which ignites a mixture of petrol vapour and compressed air inside a momentarily sealed cylinder and causes it to burn rapidly.
Inside the cylinder, the expanding gases push outward against the piston, which moves down and forces the crankshaft to rotate. As it does so, it drives other parts of the engine at different speeds and with different degrees of force.
The car is a transparent model of a modern car. The engine is visible through the body of the car. This is an experiment to examine how to make a car more energy efficient by reducing drag on the body, which could be achieved by making it more streamlined.
The car has an engine that runs on oil. The oil is stored in a tank. There is a pump that pumps the oil from the tank to other parts of the car. The engine uses electricity to turn the wheels and move the car forward.
