The internal combustion engine

Internal combustion engines are in cars, aeroplanes, ships, motor boats, tractors, snowmobiles, lawn mowers and in many other places. The engine is usually filled with petrol or diesel oil, which it then combusts internally in an enclosed container — a cylinder. This then creates high temperatures and pressure which set a plate or piston into motion — one way of converting heat into motion. Because the internal combustion engine emits carbon dioxide it is one of the main causes of climate change. The question is what should we use instead?

The big breakthrough for the internal combustion engine came in 1876 when the Germans, Nikolaus Otto and Eugen Langen presented a four-stroke engine. It came to be called the “Otto engine" and it is still the most common type of engine.
