D)neither A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because turbochargers do indeed allow for an increase in power without a substantial decrease in fuel economy by forcing more air into the combustion chamber, allowing for a more efficient burn. Technician B's statement is incorrect because while turbochargers use exhaust gas to operate, they do not rob power from the engine at low speeds; instead, they may not provide a significant boost until the engine reaches a higher RPM where exhaust flow is sufficient to spin the turbocharger's turbine.
