It is lubrication for the upper part of European engines it was banned in 1975 in the usa
The main chemical compound present in petrol is hydrocarbons, specifically alkanes such as octane (C8H18). These hydrocarbons burn easily to provide energy for engines.
It is extremely unlikely to find Iodine in petrol/gasoline. It is not deliberately added. Bromine used to be added in the form of Lead Tetrabromide.
Yes, petrol can decompose over time due to exposure to heat, light, oxygen, and moisture. This decomposition process can lead to the formation of sticky residues and gums that can clog fuel systems and reduce engine efficiency. Proper storage in a sealed container can help slow down the decomposition of petrol.
Tetraethyl lead was historically used in petrol as an octane booster to prevent engine knocking and improve performance. However, it is highly toxic and has harmful environmental effects, leading to its phase-out in many countries in favor of other additives like ethanol or MTBE.
lead compounds are harmful if added to petrol as it cause cancer, poison the catalytic converter (use to convert harmful gases into less harmful gases/harmless, emmision of greenhouse gases and increase the amount of oxides of nitrogen which results in acid rain.
can content in petrol if not unleaded
Unleaded petrol is petrol that has not been treated with a lead compound.
in petrol we have 2 types.they are 1.leaded petrol 2.unleaded petrol in leaded petrol we have lead compounds so we call it as leaded petrol. in unleaded petrol we do not have lead compounds. the use or advantage of unleaded petrol is it does not emit harmful gases in to the environment. but leaded petrol emits harmful gases. cracking process takes place in unleaded petrol. cracking means it is a process of converting harmful gases into harmless gases. but this cracking process cannot be done in leaded petrol bcoz lead compounds decomposes the catylsts used in cracking process
lead free petrol....
The beneifits of petrol is that it fuels your car and it lets it go many kilometres. Petrol is also a fossil fuel and will be around for the next hundred of years. Also petrol doesn't contain lead, unlike the earlier types of petrol which contained lead and can damage your heath. the benefit of petrol is that it gives fuel to your car so it can work and drive kilometers and more.
unleaded
It isn't anymore. That's why its called Unleaded.
It's a pollutant. A Neurotoxin.
unleaded petrol is 91 octane petrol with not a trace of anti knock compound(tetra ethyl lead)...so that it produces no harmful emissions
dangerous.....
tetraethy lead
