Discussion :: Internal Combustion Engines
- Which of the following statement is wrong?
|
A.
In compression ignition engines, detonation occurs near the beginning of combustion. |
|
B.
Since the fuel, in compression ignition engines, is injected at the end of compression stroke, therefore, there will be no pre-ignition. |
|
C.
To eliminate knock in compression ignition engines, we want to achieve auto-ignition not early and desire a long delay period. |
|
D.
In compression ignition engines, because of heterogeneous mixture, the rate of pressure rise is comparatively lower. |
