Four Stroke Combustion Engine in Operation


The internal combustion (IC) engine is probably one of the most influential machines every invented by the human mind. This model shows how a typical four stroke diesel engine operates. Note that the engine is a diesel engine (compression ignition type) and does not have spark plugs.

Invented by Rudolf Diesel in 1893 in the city of Augsburg, Germany, the diesel engine has grown to become one of the most famous machines in existence. For over 100 years the design of the diesel engine has remained mostly unchanged with only limited improvements in efficiency. In a rapidly changing world, the big question remains, what will replace it?
