Both gasoline or diesel cars utilize carbon hydrate compound as fuel, and the
thermal efficiency of engines is only about 33-45%, thus carbon deposition will
appear to all cars. Almost all cars are equipped with internal combustion
engines. The periods of intake, compression, explosion and exhaust are
controlled and fixed by a time controller. When the operation conditions turn
worse, combustion will be incomplete and carbon deposition will appear.
Carbon deposition will change the original mechanical structure of engine
interior, and induce the results of power loss, fuel waste, and parts
deterioration. Besides, carbon deposition seems always in a vicious circle,
making the performance of engine become worse and worse. If carbon
deposition can be clean periodically, then an old car may has the performance
like a new one, and the driver can enjoy the fun of driving.
