Fuel analysis
As renewable diesel and biodiesel production continue to accelerate worldwide, fuel testing laboratories face new challenges in accurately measuring ignition quality across an increasingly diverse range of fuels. The CFR F5 Cetane EFI Rating System was developed to meet these evolving industry demands, providing enhanced performance, greater operational efficiency, and improved compatibility with renewable fuel technologies.
The F5 Cetane EFI Rating System is a next-generation F5 cetane engine equipped with a modern high-pressure Electronic Fuel Injection (EFI) system. Combined with XCP® TECHNOLOGY, the system delivers precise control of fuel injection timing and quantity, resulting in superior combustion stability and improved cycle-to-cycle consistency. These advancements provide more accurate and repeatable Cetane Number (CN) measurements across conventional and renewable fuel streams.
Demand for renewable diesel continues to expand, driven by low-carbon fuel standards, renewable fuel mandates, and corporate sustainability commitments. As production capacity increases globally, fuel quality testing becomes increasingly critical to ensure compliance with industry specifications and maintain performance standards.
Accurate cetane measurement plays a vital role in characterizing renewable diesel fuels and validating product quality throughout production and distribution. The F5 Cetane EFI provides laboratories with the capability to support this growing market while maintaining the precision and reliability required by international fuel standards.
With improved fuel atomization and air-fuel mixing, a cleaner combustion chamber, and longer maintenance intervals, the F5 EFI unit delivers exceptional reliability built on a proven engine design. Robust components, including the durable crankcase and cylinder assembly, are engineered for long operating life and dependable performance. With routine maintenance and proper upkeep, users can rely on the F5 EFI to consistently meet the demands of today's fuel testing environments.
Beyond reliability, the F5 EFI provides unmatched flexibility and operational efficiency. Its intuitive touchscreen interface and guided testing prompts simplify ASTM D613 test procedures, reducing operator training requirements while improving consistency and productivity. By enabling greater resource utilization, faster testing, and reduced dependence on operator expertise, the system helps laboratories lower operating costs and maximize throughput.
The rapid growth of renewable diesel, hydrotreated vegetable oil (HVO), hydrogenation-derived renewable diesel (HDRD), and biodiesel is reshaping the global fuel landscape. Many of these fuels have very high cetane values, often exceeding 70 CN, making precise ignition quality measurement increasingly important for producers, refiners, and testing laboratories.
The F5 Cetane EFI is uniquely suited to evaluate these fuels across the full cetane scale. While traditional petroleum-derived diesel fuels typically fall within the 40–60 CN range, renewable diesel fuels frequently reach significantly higher cetane values. The EFI system offers improved compatibility with renewable diesel and biodiesel fuels compared to legacy F5 engines, enabling laboratories to evaluate these advanced fuel formulations with greater confidence and reduced maintenance requirements.
As the fuel industry shifts toward lower-carbon energy sources, the need for accurate and efficient ignition quality testing will continue to grow. Designed to support this transition, the F5 EFI combines proven cetane engine performance with modern EFI and XCP® TECHNOLOGY. It delivers precise cetane measurements for both conventional and renewable fuels, helping laboratories, refiners, and fuel producers meet current testing needs and prepare for future fuel development.
