Which process is essential for achieving power in a combustion engine?

• A. Intake
• B. Combustion
• C. Exhaust
• D. Compression

Answer: (B)

The combustion process is critical for generating power in a combustion engine. In this phase, fuel and air are mixed and ignited, resulting in a rapid expansion of gases. This expansion creates pressure, which is harnessed to push the pistons within the engine, ultimately converting chemical energy from the fuel into mechanical energy. Without the combustion process, no significant power would be produced, rendering the engine ineffective. It is this transformation of energy during combustion that drives the engine's operation, making it fundamental to the entire cycle of power generation within combustion engines.
