What is the main advantage of an OHV engine compared to an L-head engine?

  1. Lower noise levels

  2. More compact design

  3. Increased fuel efficiency

  4. Higher torque output

The correct answer is: Increased fuel efficiency

The main advantage of an OHV (Overhead Valve) engine compared to an L-head engine is increased fuel efficiency. OHV engines are more efficient in burning fuel due to better airflow and improved combustion, resulting in better fuel economy. This design allows for a more complete combustion process, leading to increased overall efficiency in the engine's operation.
