Words of Wisdom from Syd Mallet 1975.
Attention: Engine Operator Retiree’s help us preserve our Octane Engine legacy.
The folks at StanCo Scientific Inc are trying to establish a directory of past regional group meetings minutes and reports regarding the Octane Engine. We want to create an archive that can be shared with others in the community preserving the legacy and not let it slip into obscurity. A lot of our older operators […]
THE FUTURE IS KNOCKING FOR THE ANTIQUATED OCTANE NUMBER TEST, ANY TAKERS ?
Although many older drivers will recall their cars knocking when driving uphill on hot days,the average driver under the age of fifty likely has never heard an engine knock. Indeed,different techniques have been implemented in engines to avoid that annoying “pinging” sound.However, this does not mean that knock has been conquered. Rather, knock is a […]
Road Octane Numbers 1957
An interesting read on high compression US Road Octane Numbers with compression ratios 11:1 and 12:1 https://enginebuzz.com/wp-content/uploads/2020/12/Copy-of-Road-Octane-Numbers-for-Gasoline-in-Cars-5-14-1957.pdf
Great Lakes Regional Presentation on Fuel Consumption for MON and RON
Great short presentation on fuel used for a rating- remember seeing this in three different regional group presentations. https://enginebuzz.com/wp-content/uploads/2020/12/FuelConsumptionRONMON.pdf
Knock Measurement Resolution and Accuracy
I saw this presented in a Regional Group Meeting in Memphis in 2015. This is an excellent example of why the new types of digital meters may provide much more stability and reliability in the measurement. By integrating the meter into a digital output, noise rejection is increased and errors in the measurement are greatly […]
Common Sources of Error in Knock Ratings
https://enginebuzz.com/wp-content/uploads/2020/11/Sources-of-Error-in-Knock-Ratings-5-9-1960.pdf An investigative review by Ethyl Corp in 1960 still very relevant today Key Insights show how much error can be attributed to different parts of the process and system(s). Think your data is sound? Read this and take another look.
A look back at “Some Sources of Error in Laboratory Knock Ratings”
“Some Sources of Error in Laboratory Knock Ratings” by W. E. Adams and J. D. McCullough In the late 1950s, researchers at Ethyl Corporation conducted a study to look at the effects on the Research Octane Number by various variables within the engine environment. This study highlighted the differences that can be seen when pieces […]

Combination Octane Rating Unit – K90901 by Koehler Instrument Company
Test Method This laboratory test method covers the quantitative determination of the knock rating of liquid spark-ignition engine fuel in terms of Research O.N. and the Motor Octane Number, including fuels that contain up to 25 % v/v of ethanol. The sample fuel is tested using a standardized single cylinder, four-stroke cycle, variable compression ratio, carbureted, […]
