Which second function does that throttle serve?

  • A.Smooth engine shutdown by cutting the air
  • B.Power control, which is achieved by restricting the air in the same manner as on a petrol engine
  • C.Nothing
  • D.Closing at shutdown to reduce the air drawn in, which avoids the shake produced by compressing a full charge

Answer: A

Closing the intake at shutdown removes the compression shake. The last option explains exactly that benefit, which makes it a correct and more instructive version. Diesel power is controlled by fuelling. Naming what changes and what stays the same is the reliable route through questions of this shape. Tracing the requirement back to the physical constraint that produces it makes the answer follow. The quantity that varies and the quantity that does not are worth naming before any substitution is attempted.
