Evaluation Methodology for Intake Valve and Combustion Chamber Deposits Formation on Port Injection Flexible Fuel Spark-Ignition Engines 2012-36-0489

This work presents a new methodology to evaluate intake valve and combustion chamber deposits formation on port injection flexible fuel spark-ignition engines. This test methodology was adapted from ASTM 6201 standard, using a commercial Brazilian engine that can be run with blends of gasoline and ethanol in any proportion from pure gasoline to pure ethanol.
It also describes every step of the methodology development, test conditions and the main criteria discussed by workgroup created by The National Agency of Oil, Natural Gas and Biofuels - ANP to propose a suitable standard for Brazilian spark ignition engine's fuels.
This methodology will also be used to evaluate the results of detergent dispersant additives that may comply with the compulsory Brazilian gasoline additivation that will be due at January 2014.
