Question

there are two common types of electric egr valves: the pulse - width - modulated solenoid type and the ​________ motor egr valve type.

a. diaphragm
b. hopper
c. stepper
d. control

Explanation:

Electric EGR (Exhaust Gas Recirculation) valves are important components in engines. The two common types are the pulse - width - modulated solenoid type and the stepper motor type. A stepper motor can precisely control the valve position. A diaphragm is more related to vacuum - operated systems (not electric in this context). A hopper is a container - like structure (not relevant here). A control is a general term and not a specific motor type for EGR valves in this classification.

Answer:

C. Stepper
