Q204
The spark ignition engines are governed by
A.
Hit and miss governing
B.
Qualitative governing
C.
Quantitative governing
AnswerD.
Combination of (B) and (C)
Answer: Option C
Solution
Answer: Option C
Solution:
-The spark ignition engines are governed by Quantitative governing.
-SI engines being quantitatively governed by controlling the quantity of charge inducted, leading to high throttling losses.
-To qualitatively govern the engine, charge purity was reduced by incorporating EGR, thereby reducing the amount of available oxygen in the charge inducted.
