Impact of the Composition of a Multifunctional Additive Package for Diesel Fuel on Engine Power.

Multifunctional fuel additive packages (MFAPs) are critical for the production of modern diesel fuels with improved performance and environmental characteristics. The most significant property of these packages is the cleaning ability determined in relation to fuel injectors, but this property does not determine the advantages of using MFAPs, which are most often formulated by fuel and additive manufacturers as the ability to increase, restore and maintain engine power at a high level. In this study, an instantaneous and reproducible increase in engine power of 3.9–4.4 % was recorded when switching to fuel with an additive, regardless of the composition of diesel fuel and diesel engine design, while the influence of each component of the multifunctional additive on the recorded effect was determined. An assumption was made about the mechanism of power increase associated with an increase in fuel combustion efficiency, and not the cleaning mechanism of the additive. [ABSTRACT FROM AUTHOR]
