Answer 2

                            KNOCKING:

Its that annoying sound that you hear at the days cold from your vehicle , yes of course its the same sound that you get when a random stranger hits a BANG!BANG! loud at the door like in horror movies.


SO WHY DOES YOUR VEHICLE SOUND LIKE THAT?????

Dont worry there is no ghost in your vehicle

REASON FOR KNOCKING OF YOUR ENGINE
1.)   Improper combustion/ignition
2.)Insufficient octane in the gasoline
3) Over heating
4.) lagging between the fuel being injected and combustion being started

are the few reasons for knocking

HOWEVER ANTI KNOCKING REAGENTS ARE BEING USED TO STOP IT
1.)BENZOLE
2.)METHYL TERTIARY BUTYL ETHER: (MTBE)

ARE FEW OF THE ANTI KNOCKING REAGENTS
