Question

an engine can be identified by which feature? select one: a. weight b. gear ratio c. head bolt torque d. number of cylinders

Explanation:

The number of cylinders is a distinctive feature for engine identification. Different engines have different numbers of cylinders which affects their performance and design. Weight can vary based on materials and other factors not unique to engine type. Gear ratio is related to the transmission, not the engine itself. Head - bolt torque is a maintenance specification, not an identifying feature.

Answer:

d. Number of cylinders
