AG Mechanics CDE Practice Exam

Which type of engine typically uses an overhead valve configuration?

1. OHV engine

2. 2-stroke engine

3. Rotary engine

4. Electric engine

The correct answer is: OHV engine

OHV stands for Overhead Valve engine, which is a type of internal combustion engine where the intake and exhaust valves are located above the combustion chamber within the cylinder head. This configuration allows for better airflow and more efficient combustion, resulting in increased power output and fuel efficiency. In comparison, a 2-stroke engine does not have valves like an OHV engine; a rotary engine operates on a different principle using a rotating triangle within a chamber rather than traditional pistons and valves; and an electric engine does not have valves like internal combustion engines do. Therefore, the correct answer is A, OHV engine, as it is the type of engine that typically uses an overhead valve configuration.
