In the ever-evolving world of fuel testing and certification, the CFR® F1/F2 Octane Rating Unit stands tall as the unrivaled standard. Decades of innovation and dedication have solidified its position as the global benchmark for assessing the anti-knock properties of motor fuels, be it gasoline, fuel components, or alternative fuels. Since the historic debut of the CFR octane rating engines in 1929, CFR has been at the forefront of shaping the fuel testing landscape. Collaborating closely with the automotive and petroleum industries, we persistently refine the CFR product line to empower fuel producers and engine manufacturers to create more harmonious and high-performance products.

Setting the Standard

The CFR F1/F2 octane rating engines serve as the designated equipment for fuel testing in accordance with prestigious standards such as:

ASTM D2699: The Standard Test Method for Research Octane Number of Spark-Ignition Engine Fuel

ASTM D2700: The 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

Seamless Integration for Confidence

A comprehensive CFR Engines Inc. octane fuel testing system encompasses four essential components, each meticulously designed to harmonize and yield trustworthy results. Comprising the Engine Air Control System, the F1/F2 octane rating engine, XCP™ Technology, and a CFR® exhaust surge tank, this setup expertly regulates every pivotal parameter essential for a successful octane test. Whether opting for a complete unit, an upgrade/conversion kit, or genuine CFR service parts, rest assured that the product has been rigorously crafted, manufactured, and tested by CFR to function seamlessly as an integrated solution for your operations. Trusting the CFR octane rating system to fulfil its role enables users to divert their focus from making the system function and channel it towards other imperative tasks.

Data Integrity with XCP Technology

The XCP Digital Control Panel emerges as the guardian of data integrity, automatically capturing and presenting crucial information in a user-friendly Excel-based report. This streamlined approach reduces manual data entry and the likelihood of calculation errors. The standard XCP report includes KI values, Octane Numbers, environmental data (temperatures, pressures, barometer, and EACS humidity), and KI vs. fuel level curves. Additionally, the XCP can be seamlessly integrated into a Laboratory Information Management System (LIMS), delivering an automated data capture and processing mechanism that bolsters the credibility of your ratings.

Proven Reliability

For nearly a century, CFR Engines Inc. has been the bedrock of reliability for thousands of users worldwide. This unwavering trust has been sustained through a consistent series of well-thought-out system upgrades and product enhancements. CFR octane and cetane testing systems and components, including the robust engine crankcase and cylinder/head, are engineered to endure and provide unmatched operational longevity. With minimal maintenance and care, CFR octane rating engines continue to meet the rigorous demands of contemporary fuel testing, delivering authentic engine-based Octane Numbers.

Precision Through Advanced Instrument Control

The CFR F1/F2 Octane Rating Unit, armed with XCP Technology, harnesses digital instrumentation to meticulously record and process vital facets of system operation and performance. Onboard barometric pressure adjustments, heightened automation, an extensive octane meter range, elimination of adjustments for “spread,” and precise control of engine intake air are among the myriad advantages of the CFR fully integrated instrument system. These enhanced, more accurate measurements, driven by an intuitive interface, culminate in an overall boost in precision.

Cost-Efficiency Through Versatility

The CFR F1/F2 Octane Rating System affords users unparalleled flexibility and cost-efficiency through standardized product offerings. By implementing a few straightforward component changes and activating push-button controls, users seamlessly switch between any of the four test procedures outlined in ASTM Methods D2699 or D2700. These cost savings materialize in optimized resource utilization, expedited test transitions, reduced operator training overhead, and enhanced repeatability—all achieved with a single system.

A World of Features

The CFR F1/F2 Octane Rating Unit offers an array of additional features, including:

XCP integrated safety monitoring system with shutdown safeguards for power loss, low oil pressure, overheating, and electrical overload

Intuitive touch-screen HMI panel for unit operation and octane rating tests

Built-in prompts to guide operators through test procedures for all ASTM methods, ensuring consistency across operators
