2-Ethylhexyl Nitrate CAS#27247-96-7

Outstanding Boost to Diesel Cetane Number
2-Ethylhexyl nitrate serves as a high-performance cetane booster. When blended into diesel fuel, it remarkably elevates the fuel’s cetane rating. The upgraded cetane value delivers gentler, faster ignition, eliminates harsh knocking during startup and acceleration, and brings consistent, smooth ignition performance under both low-temperature and regular operating conditions.
Optimized Combustion Process with Higher Thermal Efficiency
This additive greatly shortens the ignition delay of diesel sprays inside combustion chambers. With shortened lag time, fuel droplets ignite instantly and burn more thoroughly instead of incomplete burning. The optimized combustion cycle brings snappier throttle response, steadier engine idle and long-duration stable running without jitter.
Reinforced Engine Power & Optimized Fuel Economy
Full and sufficient combustion converts more fuel chemical energy into mechanical power. Engines treated with this additive gain noticeable power and torque output, while cutting redundant fuel waste caused by unburnt substances. It perfectly balances strong driving performance and lower overall fuel consumption to reduce operational costs.
Effective Reduction of Toxic Exhaust Pollutants
Incomplete fuel burning is the primary source of particulate matter, black smoke and nitrogen oxide emissions. By facilitating full combustion, this cetane improver restrains the generation of PM particles and NOx drastically. It helps vehicles and machinery meet stricter environmental emission standards, cutting exhaust pollution and lessening harm to the ecological environment.

2-Ethylhexyl Nitrate (CAS No. 27247-96-7)

Recognized as a high-performance, industry-standard premium cetane improver, 2-Ethylhexyl Nitrate is an indispensable functional additive widely adopted in the blending and refining of all types of commercial diesel fuels, ranging from light vehicle diesel to heavy-duty truck and engineering machinery diesel. When incorporated into base diesel at the recommended, well-balanced dosage range, this product can deliver a striking, measurable improvement to the fuel’s cetane index, fundamentally optimizing the overall combustion characteristics and thermal efficiency of diesel inside engine combustion chambers.

The core working principle of this additive centers on effectively cutting down the ignition delay interval of atomized diesel mist after injection. By minimizing the lag time between fuel injection and ignition, it enables the fine fuel droplets to ignite rapidly and burn in a thorough, uniform manner, largely eliminating incomplete combustion and local carbon accumulation that commonly occur with low-cetane diesel. This greatly refined combustion cycle generates a series of comprehensive, practical advantages for diesel engines of all specifications.

First of all, it significantly elevates overall engine power and low-speed torque output, resulting in snappier throttle response, smoother cold startup and stable idle operation without harsh knocking noise. Secondly, the maximized utilization of fuel chemical energy helps reduce redundant fuel loss caused by unburned residues, effectively lowering comprehensive fuel consumption and bringing prominent cost savings for fleet operators and industrial users. Furthermore, by avoiding partial combustion, the product drastically curtails the formation of toxic exhaust contaminants such as particulate soot, particulate matter (PM) and nitrogen oxides (NOₓ). It helps diesel-powered equipment meet increasingly stringent global emission standards, facilitates cleaner exhaust discharge and lessens the long-term environmental footprint of diesel operation.
