Combination Research & Motor Method Octane Rating Unit * Trademark of General Electric Company

The Waukesha CFR F1/F2 Combination Octane Rating Unit More than 80 years ago, GE’s Waukesha gas engines pioneered a system for fuel rating that today remains the standard for defining the anti-knock qualities of motor fuel gasoline, fuel constituents and alternative fuels. By providing a stable test platform for accurately defining fuel anti-knock quality, the Waukesha CFR Octane Rating Unit has given the automotive and petroleum industries the ability to tailor ailor their respective products to perform together ether more effectively. Accurate anti-knock fuel el quality testing has led to development...

The CFR Octane Rating Unit with XCP Digital Control Panel Designed for Today’s Fuel Testing Facilities The latest generation of Waukesha CFR octane rating units combines the easy-to-use features of a digital control panel with the robust engine design that users expect from GE’s Waukesha gas engines. The CFR F1/F2 Combination Octane Rating Unit with XCP Digital Control Panel is widely accepted in today’s fuel testing laboratories. It is in ASTM Methods D2699-10 (RON) and D2700-10 (MON), and conforms to IP237 and IP236. The XCP Panel The fuel rating process takes a big step forward with the XCP™...

Key Design Features Variable Compression Ratio Cylinder and Sleeve Assembly At the heart of the CFR system is the variable compression cylinder and sleeve assembly by which the knock characteristics of unknown fuels can be determined. Varying the compression ratio by manipulating the cylinder height during engine operation produces various levels of knock intensity, making it possible to compare unknown fuels to reference fuels with known octane values. Cylinder height is correlated to a compression ratio which then can be directly correlated to a specific octane value through ASTM method specifications....

Intake Air Humidity Equipment Exhaust Surge Tank System A humidity control system – either an ice tower and related equipment, or an intake air refrigeration unit – manages the moisture content of the combustion air going into the CFR octane rating unit. Maintaining humidity levels at a constant 25-50 grains of moisture /lb. of dry air, is prescribed by the ASTM method for producing consistent octane ratings. The CFR octane rating unit is equipped with a surge or expansion tank that eliminates the resonant pulsations and back pressure that occur in the CFR rating unit’s exhaust lines during operation....
