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.
Petrol is highly flammable and volatile, making it dangerous to use as a fuel in stoves. Its combustion can produce harmful fumes and emissions, posing health risks. Additionally, petrol burns at a higher temperature than is typically needed for cooking, which can lead to food burning or the stove malfunctioning.
The volatility of a petrol fuel system refers to how easily the fuel evaporates when exposed to air or heat. A highly volatile fuel system may lead to increased vapor emissions, reduced fuel efficiency, and potential safety hazards. Proper maintenance and use of fuel stabilizers can help regulate volatility in petrol fuel systems.
Antiknock additives like tetraethyllead (TEL) or methylcyclopentadienyl manganese tricarbonyl (MMT) are added to petrol to prevent engine knocking. These compounds increase the octane rating of petrol, reducing the likelihood of premature ignition in the engine.
IPA is miscible with petrol.
As petrol is a mixture, it has no exact formula. However, the largest component of almost all commercial petrols is isooctane, which has the formula C8H18, and its isomers, which have the same formula of disel
can content in petrol if not unleaded
Unleaded petrol is petrol that has not been treated with a lead compound.
WHAT ARE THE BASIC PARTS OF PETROL ENGINE? HOW DOES PETROL ENGINE WORKS?
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....
Spark timing
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.....
