Artigo Completo:

Nowadays in some Brazilian regions the fuel available to the customer has 500 ppm of Sulphur with currently biodiesel percentage (B7 and from march’17 on B8) defined by Petroleum, Natural Gas and Biofuels National Agency (ANP) and after nearly 6 years of Euro V implemented in Brazil the fuel distributor has no time to phase out of this diesel in order to distribute only Low Sulphur Diesel BS 10. Currently it’s necessary to validate all vehicles with Diesel BS 500 in order to be sold to Brazilian North Region customers. We could confirm main filter with low performance and also fuel injector’s failure as a consequence of low performance indication. All injectors were evaluated and we could confirm deposits due to high temperature and contamination that avoid the diesel spray inside engine combustion chamber. Analyzing all fuel lines and filters (pre filter and main filter) housing and it was possible to find out organic contamination after one week of all components replaced. Evaluating diesel from main tank and durability vehicles tanks, the results have shown property losses after one week of fuel usage. It was evaluated the results of low oxidation stability according to Rancimat modified (EN 15751:2014) analysis methodology and check the relation with vehicle performance lost.
