Waukesha Cfr Octane Engine-How to Calculate the Octane Number

There are still many older models Waukesha Cfr octane engine in use in the octane test lab. And for the older model octane engines, operators need to manually calculate the octane number, after the end of each octane test.

The octane test results for bracketing procedure are calculated manually as follows:

Calculate the average knock meter readings for the sample fuel and each of the PRF blends.

Calculate the O.N. by interpolation of these average knock meter readings proportioned to the O.N. values of the bracketing PRF blends. And how to calculate the octane number of the sample in accordance with the example shown as below:
