Aviation Fuel Rating: CFR F4

Worldwide, more technicians rely on the Waukesha CFR F4 engine for the critical process of determining the supercharge octane ratings of aviation gasoline and aviation gasoline blending components. It is the only fuel rating instrument that conforms to both ASTM D909 and IP 119 fuel specifications. The technology for determining the supercharge octane number for aviation gasoline is an outgrowth of the original fuel rating technology that was pioneered by GE’s Waukesha gas engines. 

Features & Benefits

  • Conforms to ASTM D909 Standard Test Method for Knock Characteristics of Aviation Gasolines by the Supercharge Method.
  • Accuracy and productivity. Data acquisition and computerized instrumentation for tight operation control and fewer measurement and recording errors.
  • Precision measurement.  Temperature and pressure measurement control and computerized calibration of fuel/air ratios. Displays test method parameters in easy-to-read format.
  • Easy operation. Electronic fuel flow measurement via touch-screen monitor. Dynamometer-based system also controls engine speed.
  • Versatility. Air intake system conditions air to simulate blown or super-charged engines.
  • Easy to service. Simply-designed crankcase for easy measurement and repair of key components.

Application

CFR F4 units are recognized worldwide for producing consistent, accurate test results in  determining the supercharge octane number for aviation gasoline.
