knocking is caused by fuel in the combustion chamber igniting before the piston reaches TDC (top dead center). normally because the compression ratio is to much for the fuel. as the piston comes up it creates compression (pressure) that pressure heats the fuel, and if the pressure or heat is to much the fuel/air mix will self combust before the spark plug ignites it (these same principles are what makes a diesel motor run). a higher octane fuel can simply hold up to this pressure because it burns hotter

When you see an octane 95 RON what does the RON mean?
RON stands for Research Octane Number, which is a standard measure of a fuel's ability to resist knocking in a combustion engine. An octane rating of 95 RON indicates that the fuel has a higher resistance to knock compared to lower octane-rated fuels.
Guide number for gasoline?
The guide number for gasoline refers to the ignition quality of the fuel. It is indicated by the octane rating, with higher numbers indicating better resistance to engine knocking or pinging. Gasoline with a higher octane rating is typically recommended for high-performance or turbocharged engines to prevent knocking and improve overall engine performance.
What is the difference between a strike and spare?
The different between a strike and a spare is the number of shots used in knocking all 10 pins down. A strike is knocking all 10 pins down in one shot. A spare is knocking all 10 pins down in two shots.
What causes the rear tire to make a knocking sound when stopping?
Your rear tire could be making a knocking sound for a number of reasons. You could have a damaged strut or axle that needs replacing.?æ
What is the measure of the antiknock properties in a fuel?
The measure of antiknock properties in a fuel is typically expressed using the octane rating system. Higher octane ratings indicate better antiknock properties, meaning the fuel is less likely to cause knocking or pre-ignition in an engine.
What is 14.9 rounded to the ones place in a mixed number?
Rounding to ones eliminates decimals. 14.9 rounds to 15
What causes a Knocking noise in rear end?
Can be a number of things, the first thing to check would be the Subframe Bushes
The octane number of zero is assigned to?
The octane number of zero is assigned to n-heptane, which is a straight-chain hydrocarbon with poor resistance to knocking in an engine. This serves as the baseline for the octane rating scale, with higher numbers indicating better anti-knock performance.
Does a freezer temperature get warmer if the dial is on a higher number or colder?
A freezer temperature gets colder when the dial is set to a higher number. The higher the number on the dial, the colder the freezer will be.
What can you do to cut down the number of angles at which light enters the eye thereby knocking out a lot of image that would be blurry anyway?
squint
What is meant by the knock range of an engine?
It is the octane number range the distributor automatic spark advance can handle without the engine knocking.
How do you determine the octane number of your engine?
If you listen to the engine under load conditions and it rattles or pings then you should use a higher octane fuel but you should research more on this through these pages to determine the need for a higher octane value before you tear something up.
