1. Emission and Deposit Formation in Direct Injection Stratified Charge SI Engines
Abstract : A promising approach to increase the efficiency of the spark ignition (SI) engine is to inject the fuel directly into the cylinder to form a stratified charge. There is a potential to reduce the fuel consumption at low speeds and loads by 20 - 25% compared with conventional SI engines with stoichiometric homogeneous charge. READ MORE

2. Real-time breath gas analysis of carbon monoxide : laser-based detection and pulmonary gas exchange modeling
Abstract : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract.

3. Combustion Engine Characterization and Development by Means of Laser Diagnostics
Abstract : Planar laser induced fluorescence (LIF) has been utilized for two-dimensional imaging in combustion environments. By using tracer LIF the fuel distribution prior to ignition has been monitored in a GDI-engine. READ MORE

5. Development of Dual-broadband Rotational CARS for Combustion Diagnostics
Abstract : The present thesis concerns development and application of dual-broadband rotational coherent anti-Stokes Raman spectroscopy (DB-RCARS) for temperature and species concentration measurements in combustion processes. Both fundamental development of the technique, including experimental as well as modelling results, and measurements in practical combustion devices were conducted. READ MORE
