الملخص الانجليزي
Piston engines are the largest group of thermodynamic heat engines in use today. It is used in many different applications, it’s found in all kinds of transportation, from a small size motor vehicle to aircraft. The reason of this wide use of those engines is their high energy convergence efficiency, and the high fuel to energy ratio they provide. There are two main types of piston engine: the spark-ignition engine and the diesel engine. The diesel engine is more efficient but it also generates more pollution. There are also two common engine cycles: the two-stroke cycle and the four-stroke cycle. It should be stressed that many prospective studies suggest that up to 60% of the cars will still use piston engines as main power source in 2050.
