A Study on the Effects of Sequential Turbocharged Diesel Engines

Sequential turbocharging is a technique where multiple turbochargers are connected to an engine. These turbochargers are switched in sequentially. The manufacturers of engines with this system claim that the part-load and transient performance is better in comparison to engines with a single turbocharger. These claims and other effects in these...

Study of Effects on Performance of a Diesel Engine due to varying Back Pressure for an Underwater Exhaust System

Two-part modelling format for modelling marine diesel engines in joules

The modelling approaches can go to two extremes: fully data-oriented and fully process oriented. Modelling for diesel engines is not excluded. Usually data-oriented is computational friendly and accurate and the latter is detail and flexible. A high-speed diesel engine model is missing in project JOULES. The objective of this work is to develop...

Optimizing diesel engine condition monitoring: Research on diagnostic representation techniques based on in-cylinder pressure measurement

The aim of this thesis is to investigate whether other representation techniques of the in-cylinder pressure signal, besides the current pressure-crank angle curve, have the potential of improving the diagnosis in a condition monitoring program. Investigated are the quantitative representation of the heat release through Vibe parameters and the...
