Explanation:
The Otto cycle is a thermodynamic cycle that is used in spark-ignition internal combustion engines (ICEs). It consists of four processes: intake, compression, power, and exhaust. In this cycle, the heat addition and heat rejection take place at constant volume and constant volume, respectively.
Heat Addition:
During the power stroke, the fuel-air mixture is ignited by a spark plug. The resulting combustion causes a rapid increase in pressure and temperature inside the cylinder. This process is known as the heat addition process. The heat addition process takes place at constant volume because the piston is held in a fixed position by the crankshaft, and the volume of the combustion chamber does not change during this process.
Heat Rejection:
After the power stroke, the exhaust valve opens, and the burned gases are expelled out of the cylinder. This process is known as the exhaust stroke. During this stroke, the pressure and temperature inside the cylinder decrease rapidly. This process is known as the heat rejection process. The heat rejection process takes place at constant volume because the piston is still held in a fixed position by the crankshaft, and the volume of the combustion chamber does not change during this process.
Conclusion:
Hence, it can be concluded that the heat addition and heat rejection take place at constant volume in an Otto cycle.
