Data Integrity with XCP Technology
The CFR® F1/F2 Octane Rating Unit is the globally accepted standard for determining and certifying the anti-knock characteristics of motor fuels – whether gasoline, fuel constituents, or alternative fuels. Since the release of the first CFR octane rating engines in 1929, CFR has been at the forefront of establishing test methods for rating fuels. Working hand-in-hand with the automotive and petroleum industries, we continue to enhance the CFR product line to help fuel producers and engine manufacturers develop products that perform together more effectively.
The CFR F1/F2 octane rating engines are specified equipment for testing fuels according to:
ASTM D2699: Standard Test Method for Research Octane Number of Spark-Ignition Engine Fuel
ASTM D2700: Standard Test Method for Motor Octane Number of Spark-Ignition Engine Fuel
IP 236: Determination of Knock Characteristics of Motor and Aviation Fuels – Motor Method
IP 237: Determination of Knock Characteristics of Motor Fuel – Research Method
Central to the CFR Octane Rating System is the single cylinder engine. The engine is driven by an electric motor to ensure constant speed for the test. The machine tolerances, temperatures, pressures, and fluid flows are all closely managed within the engine to eliminate outside variables that can affect the test. The engine utilizes a unique variable compression cylinder to change the engine compression ratio, either for tuning as part of test setup or as a variable during the test. Lastly, fuel is delivered to the engine in a controlled manner through a precise carburetor and venturi assembly. In an Octane test, all variables are fixed except for compression ratio or air/fuel ratio depending on the chosen test procedure. By controlling all engine variables but one, the CFR instrument can measure how the sample fuel performs over time relative to changes of the single variable.

Providing value and confidence in global fuel quality
The CFR® F1/F2 Octane Rating Unit is the globally accepted standard for determining and certifying the anti-knock characteristics of motor fuels – whether gasoline, fuel constituents, or alternative fuels.
Providing value and confidence in global fuel quality
A complete CFR Engines Inc. octane fuel testing system includes four main elements, each designed to seamlessly integrate and deliver trusted results. With the Engine Air Control System, the F1/F2 engine unit, XCP® Technology, and a CFR® exhaust surge tank; each critical parameter of a successful octane test is controlled. The product is designed, manufactured, and fully tested by CFR in North America to work as an integrated solution. Confidence in the CFR system to do its job, allows users to focus what they do best.
Data Integrity with XCP Technology
With XCP, critical information for each rating is automatically captured and presented in an Excel-based report, minimizing manual data recording and calculating errors. The standard report of XCP is exportable to LIMS and includes KI values, Octane Numbers, environmental data (temperatures, pressures, barometer, and EACS humidity), and KI vs fuel level curves. Automatic capture and processing of test data gives a user the accountability needed to trust their CFR unit and defend ratings without challenge.
Reliability of Proven Design
Since 1929, thousands of users have relied on the proven service of CFR products. This reliability has been consistently maintained through a long series of well-designed system upgrades and product enhancements. CFR systems and components are built to deliver unsurpassed operating life, such as the robust crankcase and cylinder, or the industrial grade Engine Air Control System. With basic maintenance and upkeep, users can expect CFR products to withstand the demands of today’s fuel testing environment with a true engine-based octane test.
Precision through Modern Instrument Control
The CFR F1/F2 with XCP Technology uses digital instrumentation to record and process critical aspects of system operation and performance. On-board barometric pressure adjustments, increased automation, broad octane meter range, no adjustments for “spread”, and control of engine temperatures and pressures are some of the many advantages of the CFR fully integrated instrument system. Accurate measurements controlled by an intuitive interface lead to better overall precision.
Cost Savings with One System Flexibility
With standard product offerings, a CFR F1/F2 Octane Rating System provides the user unmatched flexibility and cost savings. With a few simple component changes and push button control, users can easily switch between any of the four test procedures in ASTM Methods D2699 or D2700. Cost savings are realized in greater utilization of resources, quicker test changes, reduced operator training, and improved repeatability and accuracy amongst several users due to the use of a common interface.
