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, […]


SSD7400 Dual Digital Counter

New for 2019! As technology progresses, modern solutions to dated equipment not only becomes more user-friendly but frequently more economical. Continuing our efforts to simplify and modernize the testing environments of gasoline, a dual digital counter was developed. It is our attempt to provide a drop-in, modern alternative for existing dual digital counters, now made […]


SSD7200 Digital Temperature Controller

New for 2019! As technology progresses, modern solutions to dated equipment not only becomes more user-friendly, but frequently more economical. Continuing our efforts to simplify and modernize the testing environments of gasoline, a digital temperature controller was developed. It is our attempt to provide a drop-in, modern alternative for existing temperature controllers. Digital Temperature Controller […]


Digital Dual Hour Meter

New for 2019! A critical piece of equipment on Octane engine consoles is the hour meter. It tracks the life of the engine and allows operators to perform timely maintenance procedures and judge the overall life expectancy of the engine equipment. Modern alternatives are required to provide longevity for the engine console. Two 6-digit hour […]


501-C Potentiometer Linearity

“A chain is no stronger than its weakest link.”This is especially true within the scientific environment that is the knock engine lab. Every effort is made to improve the quality of results that are reported by a respective lab. All the training and maintenance procedures that have been implemented and completed may only achieve a […]
