F5 Cetane EFI Rating System with XCP® TECHNOLOGY

The CFR F5 Cetane EFI (Electronic Fuel Injection) Rating System is the globally recognized standard for determining and
certifying the ignition quality of diesel fuels.
First introduced in 1938, the CFR F5 continues to provide a stable, accurate testing platform for defining the ignition quality
of diesel fuels.
At CFR, we are continuously applying advanced designs and innovative approaches to give our customers an enhanced
product offering.
The CFR F5 Cetane EFI enables the automotive and petroleum industries to develop new engines and fuels that perform
together more effectively. As the most accurate method to measure the cetane number of diesel fuels, the CFR F5 Cetane
EFI also helps to ensure the integrity of the fuel supply chain from refinery to the pump.
The CFR F5 Cetane EFI is capable of testing Middle Distillate fuel types: Diesel Fuel, Biodiesel, FAME, Renewables, HVO,
GTL, and Kerosene. Additional testing capabilities include Jet Fuel, Green Jet Fuel, SAF, and SATF for research purposes

Description

The F5 Cetane EFI Rating System is an innovative system which features a state-of-the-art solenoid-style automotive fuel injector with a modified nozzle to accommodate a wide range of cetane number (CN) applications. The injector is coupled with an electrically driven injection pump that delivers a constant fuel flow rate. The injection advance is not sensitive to the physical properties of the fuel, ensuring consistent timing. The injection duration is also fixed and always completes before the start of combustion (SOC).

Fuel is supplied to the injection pump under pressure, ensuring that the fuel flow rate remains stable regardless of the fuel bowl level or the physical properties of the fuel. This results in significantly less variation in fuel quantity compared to legacy systems and reduces cycle-to-cycle combustion variation. The improved atomization of the fuel leads to better air/fuel mixing, promoting cleaner combustion and longer maintenance intervals.
