Modeling of a turbocharged SI engine

Turbo charged SI engines are a major possibility in the current trend of down-sized engines with preserved drivability performance. Considering control and supervision it is favorable to have a mean value model to be used e.g. in observer design. Such models of turbo engines are similar to those of naturally aspirated engines, but there are some special characteristics, e.g. the interconnected ...

Improving Simulation Accuracy of a Downsized Turbocharged SI Engine by Developing a Predictive Combustion Model in 1D Simulation Software

In this paper we aim to develop a predictive combustion model for a turbocharged engine in GT-Power software to better simulate engine characteristics and study its behavior under variety of conditions. Experimental data from combustion was initially being used for modelling combustion in software and these data were used for model calibration and result validation. EF7-TC engine was chosen for...

Detection of Exhaust Manifold Leaks on a Turbocharged SI-engine with Wastegate

Emissions from modern SI-engines are reduced by a three way catalyst. However if there are leaks in the exhaust system before the catalyst emissions increase for two reasons. First the untreated emissions leak out. Second which is worse, due to waves in the exhaust system, oxygen leaks into the manifold and causes an oxygen sensor offset. The result is increased emissions as the air/fuel contro...

Exhaust Manifold Pressure Estimation on a Turbocharged Si-engine with Wastegate

In turbocharged engines with wastegate the exhaust pressure can change rapidly. A method to estimate the exhaust manifold pressure is presented for diagnosis of wastegate and turbocharger on spark-ignited engines. It does not require any extra sensors in the exhaust system after the calibration. A non-linear model is developed of the exhaust pressure. Estimates of the exhaust manifold pressure ...
