An external combustion engine (EC engine) is a heat engine where an (internal) working fluid is heated by combustion of an external source, through the engine wall or a heat exchanger. The fluid then, by expanding and acting on the mechanism of the engine.

One of the frequently asked questions to me from numerous people was "How diesel engine differs from a gasoline engine" Both are internal combustion engine, both of them run on a 4-stroke cycle known as Otto-cycle, both convert chemical energy of fuel.

When people talk about car race or racing games, the topic of NOS generally comes up. So actually what is NOS? How it Works? Nos, Nitrous oxide (N2O) undergoes thermal decomposition and breaks up into Nitrogen and Oxygen, when heated at 300 degree.
