Abstract:

The purpose of this work is to describe a technique that is capable of determining the induction system deposits (ISD) tendencies of gasoline, applying the ISD apparatus developed at Southwest Research Institute (SwRI®). The results showed that temperature, fuel quality, and presence or absence of lubricant oil in the sample affect the quantity and the characteristic of the deposits. Engine tests, done in a Fiat 1.4 tetra fuel engine, were carried out in order to verify the intake valve deposits (IVDs). Another bench technique, the Intake Valve Deposits Apparatus (IVDA) proposed by SwRI®, was also evaluated. It was observed that the results obtained with ISD have qualitative similarity with the trend observed for the results in the engine and in the IVDA tests. So, it can be concluded that bench-scale tests are a promising alternative to make a first screening of the gasoline samples prior to the engine tests.
