The influence of metalloorganic fuel additives on CI engine emission

The emission of particulates besides the emission of nitrogen oxides is one of the most serious problems of ecological CI engines. One means of particulates abatement is by applying catalytic additives to fuel. It suppresses particulate formation intensity and promotes the oxidation of particulates in filters. The results of influence of fuel additives (with organic magnesium) on pollution emission were presented. The studies were carried out on a Sulzer 6AL20/24 CI engine. The assessment of influence of catalytic additives to fuel on pollution was done on the basis of mathematical model analysis of the engine. It was identified that elementary emission of particulates in range of additive content lower than 0.05% is a decreasing function, and maximum abatement of emission in the considered range of engine speed and torque is about 70%, which was recognized as a very promising result.
