The new fleet of buses is fitted with Euro IV engines which are designed to be friendly to the environment and will not operate efficiently unless run by a top quality & eco-friendly fuel. They are also coupled with Selective Catalytic Reduction technology in the exhausts system, using the blue urea (AdBlue®additive); which is a non-toxic material not added to diesel (as mistakenly thought otherwise by some people) but added to a special tank in the engine. It acts as a reagent to measure and process nitrogen oxides (NOx) in the exhaust emissions to transform them into water & nitrogen (H2O + N2); which are obviously non toxic to the environment.
