What are the factors of thermal efficiencyhow does each factor affect thermal efficiency?

Factors of thermal efficiency include combustion efficiency, heat transfer efficiency, and frictional losses. Combustion efficiency refers to how well fuel is converted into heat energy, while heat transfer efficiency measures how effectively heat is transferred within the system. Frictional losses occur due to resistance in moving parts and can reduce overall energy output. Improving combustion efficiency, enhancing heat transfer mechanisms, and minimizing frictional losses can all help increase thermal efficiency.
