A Computational Study on Efficiency Improvement of a Turbocharged Diesel Engine using Advanced Engine Operating Strategies
As the negative influence of the transport sector on the environment is a well-known fact, European Union imposed a series of regulations that aim at reducing its harmful effect. In that context, in the last decade, the Diesel engine research has been directed towards increasing the engine combustion and thermal efficiency and decreasing the exhaust gas emissions. Furthermore, the efficiency increase of the entire engine cycle is planned by introducing a number of advanced operating strategies, such as optimisation of direct injection settings and employment of various exhaust gas recirculation and engine boosting systems. This research presents a numerical study on the efficiency improvement of a turbocharged Diesel engine using advanced engine operating strategies. To this end, a 3-D CFD cylinder model of a production type Diesel engine was created in AVL Fire®, and a single engine operating point was modelled. The results of normalised ROHR were fed to a 0-D engine simulation created in AVL Boost®. The 0- D engine simulation covers the entire engine system, including the intake and exhaust flow path, low and high-pressure EGR loops, EGR and intake charge cooling, and turbomachinery. 0-D simulation was used to assess the entire engine system performance and cycle efficiency for different engine operating strategies.
