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.
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.
Also, soot emissions decrease with decreasing cetane number [1] due to more homogeneous mixture formation as a result of increased pre-mixed combustion.
Nano sized zinc oxide particles in the diesel fuel improves cetane number of the fuel and improves the low temperature combustion [12, 14].
