Cetane Number Improvers (CNI)
Enhance Ignition Quality. Reduce Emissions. Improve Cold Starts.
What is a Cetane Number and Why Does It Matter?
In diesel engines, combustion begins when the fuel auto ignites under high pressure and temperature unlike gasoline, which requires a spark. The Cetane Number (CN) is a critical indicator of how easily a diesel fuel self-ignites in the combustion chamber.
Higher CN
Faster ignition, smoother combustion
Lower CN
Delayed ignition, rough engine performance, more emissions
With today’s refineries processing opportunity crudes and heavier feedstocks, diesel fuels increasingly show reduced natural cetane values. That’s where Rodanco’s Cetane Number Improvers come in.
Rodanco Cetane Number Improvers Enhancing Diesel Combustion Efficiency
Rodanco offers high performance cetane enhancers designed to improve the ignition quality of diesel fuels across refinery blending, terminal injection, cargo treatment, and cold-weather formulations. These additives boost the cetane number at minimal treat rates, ensuring faster and more complete combustion, smoother engine operation, and improved fuel efficiency.
Key Benefits
Improved Ignition Quality
Enables quicker and more efficient combustion for enhanced engine responsiveness.
Reduced Fuel Consumption
Optimized combustion lowers unburned fuel, increasing mileage and reducing operational costs.
Enhanced Cold Start Performance
Supports diesel operability in low temperature climates and seasonal blends.
Lower Engine Noise and Knock
Smooth ignition reduces combustion shocks and audible engine knock.
Reduced Emissions
Efficient burn decreases particulate matter, unburned hydrocarbons, and NOx formation.
Minimized Deposit Formation
Cleaner combustion helps prevent injector and combustion chamber fouling, reducing maintenance needs.
Applications
These Cetane Number Improvers are widely used in refinery blending pools, diesel cargo treatment, fuel terminals, off road and marine diesel markets, and any cold climate diesel formulations requiring reliable ignition performance.
Why Choose Rodanco?
