Influence of Oil Mixture on Exhaust Gas Emissions of Two Stroke Engines 2014-32-0037

Many two stroke engine for hand-held applications are equipped with muffler that contain a catalyst in order to reduce emissions.
However, one of the main problems, is to mantain the performances of the catalyst over time; this often leads to the adoption of systems with increased culling oversized issues related to weight, dimensions and temperature. One of the major causes of degradation of the catalyst is derived from elements of poison present in the oil mixture.
This study showed the results obtained by comparing different types of oils of mixture, through durability tests carried out on an engine of a brush cutter.
