Answers
The organic compound used as anti knock agent is petroleum include any of the following suitable compounds:
TETRAETHYL LEAD AND TETRA METHYL LEAD
BENZOLE
METHYL TERTIARY BUTYL ETHER
Antiknock agents are added in minute quantities to improve antiknock ratings of fuels. It aids in increasing its octane value. Higher octane value results in ignition at higher temperature and pressure thus correctly determining the time of combustion which reduces pre-ignition that can be harmful for mechanical/motor engines.
Knocking is a chemical phenomenon which occurs in the engines of vehicles running on either petrol or diesel. When there is an excess of air in the combustion chamber, pre-injection of petrol or diesel occurs. Since both are extremely volatile and combust without much pressure, small explosions occur in the engine.
Knocking is dangerous since it can affect the performance of the engine and might even lead to engine explosions. An anti-knocking agent is responsible for reacting with the compounds in the fuel, ensuring that they do not cause pre-injection of fuel and make them unreactive.
An organic compound is sold world over as an effective anti-knock agent is Tetraethyl Lead (TEL). However, its use is discouraged since it is a toxic and poisonous substance.
