The Cooperative Fuel Research (CFR) engine is used extensively throughout the world for testing, research, and instruction in the performance of fuels and lubricants for the internal combustion engine.

The KAUST CFR is a unique and versatile system in that it can operate using a wide range of fuels such as gasoline, jet, diesel fuels, or different refinery streams. It is an ideal system to study both high and low temperature combustion.
