Question

joel has noticed that his engine is not compressing properly during the compression and ignition step. what problem will this pose? a. the spark plug will not ignite the air/fuel mixture. b. there will not be any exhaust. c. the engine will run inefficiently. d. there will be more exhaust.

Explanation:

Proper compression is crucial for efficient combustion in an engine. When compression is inadequate during the compression - ignition step, the air - fuel mixture may not burn completely, leading to inefficient operation. The spark plug can still ignite the mixture, there will be exhaust, but it won't be more exhaust due to compression issues directly.

Answer:

C. The engine will run inefficiently.
