The cetane number is a key property of diesel fuel, as it measures its aptitude to self-ignite in the combustion chamber. [8] The auto ignition temperature of diesel fuel is around 220 °C (428 °F) at atmospheric pressure. Cetane improver additives are used to decrease this temperature and lead to quicker combustion, by increasing the cetane ...
Hence, higher speed diesel engines operate more effectively with higher cetane number fuels. In Europe, diesel cetane numbers were set at a minimum of 38 in 1994 and 40 in 2000. The standard for diesel sold in European Union, Iceland, Norway and Switzerland is defined by standard EN 590. Since 1 January 2001 EN 590 demands a minimum cetane ...
It is used as a diesel cetane improver. IPN is a low-sensitivity explosive, with a detonation velocity of approximately 5400 m/s. [5] Isopropyl nitrate is extremely flammable and burns with a practically invisible flame. This presents unique hazards in its handling.
winterized diesel — the No.2 diesel has been treated with additives by the diesel supplier. As the treatment with additives (1:40000 [40]) is a cheaper way to enhance No.2 fuel in winter, most stations offer winterized diesel in cold weather conditions. In regions with colder weather, most gas stations offer No.1 fuel at the same pump ...
Diesel engine operation is primarily related to the actual cetane number, and the cetane index is simply an estimation of the base (unadditized) cetane number. Cetane number should equal or exceed cetane index, depending on the amount of additive used. The most common additive is 2-ethylhexyl nitrate (2EHN).
An Audi R10 TDI LMP race car, fueled on Shell V-Power Diesel. V-Power Diesel is Shell's version of an enhanced diesel fuel, similar to BP's 'Ultimate Diesel'. Like BP Ultimate Diesel, Shell V-Power Diesel is designed for modern compression-ignition diesel engines, to facilitate enhanced engine performance along with increased engine protection, for more consistent operation and engine longevity.
