When engine knocking is detected the knock sensor sends electrical signal to the ECU. Directionally as the compression ratio of the engine increases so does the required octane number of the gasoline if engine knocking is to be avoided. Engine knocking is in fact a pulse detonation and we all known what that can do an engine. Thus, the likelihood to engine knocking is reduced and the engine runs more smoothly. Engine knocking is the premature fuel combustion that can result in power loss of the engine. Engine knocking is compression detonation or pre-ignition of fuel in the power stroke of the engine. Engine knocking is normal for 4-stroke bike.

If you have an older car or a high performance car, you may need a higher octane gasoline to help prevent engine knocking and improve engine performance. In order to prevent engine knocking at high rpm's, NGK's high-spark #7 platinums are used. Before leaded gasolines were removed from the market, bromine was used in an additive to help prevent engine "knocking". Motor mount also help prevent or at least minimize engine knocking. There was a need for improvement in the refining process for fuels that would prevent engine knocking and increase engine efficiency. This prevent engine knocking which is very common at the time of a transmission kick down. MMT is a fuel additive, which is mixed with petrol in order to prevent engine knocking. Has been used in gasoline to prevent engine knocking. Lead was originally added to prevent engine knocking. The lead compound TETRAETHEL LEAD was added to gasoline to prevent engine "knocking".

If anything, high octane gas will help reduce engine knocking in most cars (assuming your car's manual says it's okay to use such a gas). Replace Air Filter - Dirty filter can reduce fuel economy by 10% or more. Ethanol in unleaded gasoline helps reduce carbon monoxide emissions by as much as 30 percent. It is oxygen-bearing additive used to reduce engine knocking and assist gasoline burn more cleanly. An antiknock agent is a gasoline additive used to reduce engine knocking and increase the fuel's octane rating. Thereafter, the engine performance will peak and emission will reduce. Lead has also been added to gasoline to reduce engine knocking. Standard Oil began adding ethanol to gasoline to increase octane and reduce engine knocking. Lead, in the form of tetra-methyl lead or tetra-ethyl lead, is added to petrol to increase its octane rating to reduce engine knocking. Some manganese compounds have been added to gasoline to boost octane rating and reduce engine knocking.
