Answer & Solution
Correct Answer:
Option
A
In order to eliminate knocking in compression ignition engines, there should be short delay period.
- Add 1% of ethyl nitrate or any nitrate to accelerate the combustion of fuel. This process is known as “Doping” and reduce delay period considerably and hence prevent diesel knock.
- For spontaneous ignition of the fuel, we require much higher temperature this can be achieved by raising the compression ratio.
