1. Torque based estimation of diesel engine combustion phasing
Abstract : Demands on increased efficiency and reduced emission levels introduce new challenges for the design of modern diesel engines. In order to fulfill these demands, diesel engines of today are becoming more and more complex. This escalating complexity not only applies to the engine itself, but also to its control system.

3. Crankshaft speed measurements and analysis for control and diagnostics of diesel engines
Abstract : The increasing demands from governments on the engine manufactures to lower the fuel consumption, lower the exhaust emissions and to reduce the noise have lead to an intensive research in the combustion process. Measurement of the combustion process inside the cylinder is only suitable in laboratory environment due to a number of limitations; the pressure transducer needed to measure the pressure is expensive, difficult to mount in the cylinder and has a limited lifetime that is much shorter than the engine's lifetime.

4. Ion Current and Torque Modeling for Combustion Engine Control
Abstract : Engine control development constantly requires more information about the combustion process, to meet present and future environmental regulations for vehicles. The demand for combustion monitoring and control from enginedevelopers drives the research in several parallel fields of technology to find the best and most cost effective sensor solution for each case.
