Abstract Turbocharging plays a fundamental role not only in improving the performance of automotive engines, but also reducing fuel consumption and exhaust emissions spark-ignited biofuel, diesel, liquid, gaseous engines. Dedicated experimental investigations on turbochargers are therefore needed to evaluate better understanding its performance. The availability information steady flow turbocha...

J. Cebulski, Silesian University of Technology, Institute of Material Science, Katowice, Poland This paper presents a possible application of the state-of-the-art alloys based on the FeAl intermetallic phases as materials for the manufacture of heat-proof turbine components in an automobile turbocharger. The research was aimed at determining the resistance to corrosion of Fe40Al5CrTiB alloy in ...

The drive to reduce engine emissions has placed an emphasis upon turbocharging especially with the trend of engine downsizing (C. Macrae, (2006), A. Lefebvre et al. (2005)). Turbocharged vehicles exhibit a weak point of poor drivability under transient running conditions. Previous work by Y. Matsura et al (1992), has reviewed various methods of improving the transient engine performance. This p...

In turbocharged engines with wastegate the exhaust pressure can change rapidly. Two methods to estimate the exhaust manifold pressure are compared for diagnosis of wastegate and turbocharger of a spark-ignited engine. One relies on the first law of thermodynamics and produces changes in exhaust manifold pressure. The second uses a model of the mass of remaining exhaust gases in the cylinder and...
