With increasing need for reducing the ignition delays during combustion, demand for the cetane improvers is expected to rev up.
Demand for high quality 'clean burning diesel', with high cetane, almost no sulphur and limited emissions is driven by public opinion, new legislation and fuel efficiency requirements.
Besides reduction of sulfur content of the gasoil, its Cetane number will increase from 2 to 5, he added.
It cleans diesel injector deposits across a range of injector technologies and comes with Cetane Improver.
Independent lab certified to reduce Diesel Particulate Matter (DPM) by 20% and overall emissions by 21% and has been shown to deliver an average Cetane rating over 52 when added to regular diesel fuel at fill up, Dynamo[TM] Diesel Cetane Booster also improves engine performance, power, and increases miles per gallon along with improving cold flow, increasing lubricity and cleaning fuel injectors.
According to this resolution, at least eight quality parameters of diesel are analyzed in official monitoring laboratories: aspect; color; density; flash point; total sulfur; volatility (distillation temperatures at 10% (T10), 50% (T50), and 85% (T85) recovery); cetane index; and biodiesel content [23].
Various fuel properties like kinematic viscosity, flash point, pour point, cloud point, total acid number, specific gravity, water and sediments, conradson carbon residue, sulfur contents, phosphorous contents, sulphated ash, cetane and copper corrosion were determined and found comparable to ASTM standards.
The upgraded PNS/DOE QS 013:2017: CME-blended industrial diesel oil specifications include introduction of cetane number or derived cetane number as new property, removal of distillation property, reduction in the limit of carbon residue, increase the limits of density, flash point and kinematic viscosity and updating of test method.
Cetane number (CN) is a measure of a fuel's ignition quality, with higher CN indicating auto ignition at a lower compression ratio (therefore at lower pressure and temperature) in a standard test engine [4].
Some of the renewable fuels that have been studied possess higher than normal (as compared to conventional petroleum) cetane numbers, and thus are more easily ignitable.
On the other hand, fuel additives are preferable in the case of good quality oil that needs to boost a property such as cetane number or lubricity in order to improve the engine performance.
