Abstract
By turbocharging the SI-engine, one is able to reduce the specific fuel consumption as well as the emission of certain pollutants without power losses (Vianna et al, 1989). In order to determine the causes for these reductions, measurements of pressure, temperature and velocity inside the combustion chamber of an 1.31 petrol engine have been carried out. A piezoelectric pressure transducer, a constant current and a constant temperature anemometers have been employed respectively. As compared to the normally aspirated engine, the turbocharger brings about higher pressure, temperature and turbulent intensity along the whole scope of analysis. The mixing process and consequently the quality of the burning of the fuel are improved.
