In air standard, also known as the air standard cycle, is a theoretical model used in the analysis of internal combustion engines. It assumes that the working fluid within the engine is air, and that the combustion process follows the ideal gas law.
The air standard cycle is used to simplify the analysis of engine performance by assuming that the engine operates on a closed loop cycle consisting of four processes: intake, compression, combustion, and exhaust. These processes are idealized and assume that there are no heat losses, friction, or other losses in the engine.
By using the air standard cycle, engineers can calculate various performance parameters of the engine, such as the power output, efficiency, and specific fuel consumption. It provides a simplified and convenient way to analyze engine performance, although it does not account for the real-world complexities and losses that occur in actual engines.
Overall, the air standard cycle provides a useful tool for the analysis and design of internal combustion engines, allowing engineers to evaluate the theoretical performance of the engine under ideal conditions.
