The pressure ratio does not cause pinging in an internal combustion engine. Pinging is the result of the air/fuel mixture igniying before the piston is in the propper position. Chep gas will cause pinging because it is igniting too quickly. Too high a compression ratio will do the same thing. Ingnition timing that is too far advanced will do the same thing. Back off your ignition timing two degrees at a time until the pinging stops, or buy a higher octane fuel.

What property of petrol affects engine knock?
'Knocking' in petrol engines is caused by petrols low flashpoint - its high combustibility. The octane rating is too low for the compression.
Why compression ratio of petrol enine is 8 where as diesel engine is 22?
because a diesel engine ignites its fuel with pressure, and not with a spark like a petrol engine. that is why a petrol engine does not need as high a compression ratio as a diesel engine
Why is diesel is not used in petrol engines?
Because diesel is ignited of heat and high high compresion not a spark on lower compresion petrol engine. If you use diesel in a petrol you will end up with your engine knocking and pre-detonation followed by your engine blowing up pretty bad.
Can petrol be used in diesel engine?
the system will do run for some time in knocking state and missfiress and then stops finaly...... sanaan +919997931042
What is fuel pressure in EFI Petrol Engine?
2.5 to 3.5 BAR
Which casting making petrol engine carburetor?
Pressure Die Casting
Was lead ever present in petrol?
Yes indeed! The lead compound added to petrol inhibited knocking in the engine under load. The lead also would deposit in tiny amounts on the engine valve shafts, making them tighter in their cylinders, hence reducing oil leakage and smoking. Due to health risks of engine exhausts, other ways were developed to inhibit knocking.
What is the function of lead in petrol?
Lead is no longer added to petrol because it added to both air pollution and general health risks. It used to be added for help in maintaining the general "health" of an engine's valves as well as reducing engine knocking.
Why tetraethyl lead is used in petrol?
To prevent knocking.
What is used to increase the anti-knocking property of petrol?
tetraethy lead
Is it possible to use petrol in diesel and diesel in petrol engine?
No pressure requirements for diesel much greater.There were some farm tractors built in the 1940's that started on gasoline (petrol), and switched to diesel when the engine was warmed up. So it is possible.
What causes a petrol engine to run on after it is switched off and also spit back through the carburetor?
not enough octane in your petrol. To stop the run on, turn your engine off while it is in Drive. Then switch to Park
