Anti-knock agent
Definition
A chemical substance or additive added to fuels to increase their resistance to premature auto-ignition and to prevent the phenomenon of detonation in internal combustion engines; a compound that regulates the burning rate of the fuel mixture. As an adjective, it describes a fuel, mixture, or structural effect capable of ensuring a smooth and efficient engine operation, eliminating parasitic metallic knocks.
