Octane rating is a measure of how resistant the fuel is to causing 'knocking' or pre-detonation in petrol(gasoline) engines. It is measured relative to a hydrocarbon which is rated at 100, and determined by testing in a test engine. There are two methods of testing though, which give results called RON or MON. In Europe RON is quoted, and regular petrol is about 92, though usually pumps give 95 RON fuel. In the US a mean of RON and MON is used and for the same fuel the figure is about 5 points lower, so 90 would be the same as 95 in Europe.

What petrol reduces air pollution?
Petrol with a higher octane rating can reduce air pollution as it burns more efficiently and cleanly, releasing fewer harmful emissions. Additionally, using premium or high-quality petrol that is free of impurities and additives can help lower overall air pollution levels. Regular maintenance of the vehicle's engine and emissions control systems is also important in reducing air pollution from petrol usage.
What octane for a kx 100?
Stock can run 93 octane and if its modded you need 100 octane or higher if its a high compression build.
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.
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.
How many carbon atoms is present in petrol?
Petrol (gasoline) usually has an octane rating. It is a mixture. Since Octane is C8 a molecule of petrol (gasoline) contains approximately 8 carbon atoms.
How do you calculate octane number for petrol?
This is a very a complicated process. There are two versions of the octane rating system. Neither I nor you will be able to calculate octane because of the cost prohibitive tools needed..
What is the difference between 91 octane and 95 octane?
91 octane petrol will ignite at a lower temperature and burn faster, which can cause knocking in an auto engine. Lead compounds were added at one time to raise the octane rating, but recently engines have been redesigned to work on low (<98) octane petrol (or gas in the US colonies)
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.
What is the octane rating of methanol?
The octane rating of methanol depends on the octane rating scale measurement type used, n-Heptane is the zero point of the octane rating scale then the octane rating of methanol is 115
What does petrol contain?
petrol contains octane :}
What is unleaded petrol?
Exactly that, it is petrol that is 95 octane with NO LEAD hence the term UnLeaded.Answer:Unleaded petrol is what you have before you add the tetra-ethyl lead (or similar antiknock compound) to the base fuel. The TEL allows a cheaper and lower octane fuel mix to be made.Petrol is combination of various hydrocarbon distillates from very small molecules like butane to very long chained molecules. These are mixed to provide proper combustion in an engine. The rating for this quality is known as the octane number. Leaded compounds, if added, boost the octane rating.
What is c8h18 used for?
C8H18 is the simple version of the chemical formula for any of the isomers of octane. This is best known as a major component in petrol/gasoline, although the octane rating is not related to the actual amount in the petrol/gasoline which is a mixture of several volatile hydrocarbons.
What is the difference between petrol and ultimate petrol?
Premium or ultimate just has a higher octane rating than regular. It will provide no more power, or mileage in an engine designed to run on regular.
What octane is kerosene?
It has no octane rating.

How is unleaded petrol formed?
Unleaded petrol is what you have before you add the tetra-ethyl lead (or similar antiknock compound) to the base fuel. The TEL allows a cheaper and lower octane fuel mix to be made. Petrol is combination of various hydrocarbon distillates from very small molecules like butane to very long chained molecules. These are mixed to provide proper combustion in an engine. The rating for this quality is known as the octane number. Leaded compounds, if added, boost the octane rating. ----------------------------------- Leaded petrol is now banned in many countries. The tetra-ethyl lead is extremely toxic and cause pollution. Unleaded petrol may contain methanol, ethanol, MTBE, ETBE, etc.
