what is knocking
Knocking in spark-ignition internal combustion engines occurs when combustion of the air/fuel mixture in the cylinder does not start off correctly in response to ignition by the spark plug, but one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front. The fuel-air charge is meant to be
Analysis & Control of Knock in SI Engines. P M V Subbarao. Professor. Mechanical Engineering Department. Measures to Avoid Uncontrollable Combustion. The Knock in SI Engines. Knock in gasoline engines is one of the major challenges to design an engine with higher thermal efficiencies. Without knock, an engine
Antiknock agents are the chemical compounds added in small quantities (less than 1 percent) to motor fuels to improve the antiknock ratings of the fuel. Usually added to gasoline to raise its octane value. Higher octane value means gasoline will i
Although the above fuel ignition indices, RON, MON, and OI, have been used to describe fuel anti-knock properties in automotive engineering, the relationship between RON/MON and OI/K is still not clear. This is because auto-ignition in internal combustion engines is directly associated with the combustion chemistry of
Knock ratings of gaseous paraffins and olefins through C4, and of carbon monoxide, were determined by current motor and aviation test methods. Auxil- iary apparatus and modifications of test engines necessary to rate gases are described. Antiknock qualities of ethyl and normal butyl alcohol and acetone, both alone.

Knocking, in an internal-combustion engine, sharp sounds caused by premature combustion of part of the compressed air-fuel mixture in the cylinder. In a properly functioning engine, the charge burns with the flame front progressing smoothly from the point of ignition across the combustion chamber. However, at high
SI Engine Knock. 1. Knock is most critical at WOT and at low speed because of its persistence and potential for damage. Part-throttle knock is a transient phenomenon and is Also see any other photos of knock damage to pistons, such as: cameronassociates.org.uk/assets/images/autogen/a_ Fuel anti-knock rating.

19 Dec 2017 Full-text (PDF) | SAE Paper 2001-01-3584 This is the first part of a two-part study on how to define the anti-knock quality of practical fuels. Knock intensity is measured in two single-cylinder research engines using different fuels at different mixture strengths, throttle settings and two compre
