Question 155Motor Plants - 1st Asst/Chief70% to pass
Which of the following devices will increase the power output of a diesel engine without increasing its frictional load?
AI Explanation
The correct answer is B) Turbine-driven centrifugal blower.
A turbine-driven centrifugal blower increases the power output of a diesel engine without increasing its frictional load. This is because the turbine is driven by the engine's exhaust gases, which means it does not draw additional power from the engine itself. In contrast, the other options, such as a gear-driven centrifugal blower, Roots-type rotary blower, or positive displacement blower, would increase the engine's frictional load and reduce its overall efficiency.
The use of a turbine-driven centrifugal blower, also known as a turbocharger, is a common method for increasing the power output of diesel engines without significantly increasing their frictional load or fuel consumption.
