Abstract
The goal of this research was to evaluate and contrast the performance of various engine types. The study was conducted on a sample of two engines, one of which is an Internal Combustion engine and the other is an External combustion engine. The internal combustion engine has two cycles, Otto cycle is used in gasoline engines while the diesel cycle is used in diesel engines. The external engine has two cycles too, the submarine uses Stirling Cycle and the Thermal power plant uses the Rankine cycle. The engines were evaluated based on their thermal efficiency, brake power, and specific fuel consumption. The results showed that the diesel cycle had higher thermal efficiency and brake power compared to the Otto cycle. However, the two-stroke engines had lower specific fuel consumption compared to the four-stroke engines. The results indicate that each engine type has advantages and disadvantages and that the final decision should be based on the needs of the given application.
