1. Combustion Sensing Methods - in Theory and Practice
Abstract : Accurate, reliable sensors are essential parts of any control system, and there are increasing needs for feedback systems to monitor and control key parameters of automotive internal combustion engines, operating in various combustion modes and configurations, to reduce fuel consumption and engine-out emissions. Thus, there are strong motives for studying combustion sensors. READ MORE

2. Zero and Multi-Dimensional Modeling of Internal Combustion Engines with respect to Ion Current and Soot Formation
Abstract : The work presented in this thesis can be divided into the three following fields of investigation: First of all the ionization model developed in this thesis is meant to simulate the thermal ionization process or the so-called second peak. Equilibrium assumptions have been adopted for the modeling of the thermal ionization, in which Saha’s equation was derived for singly ionized molecules. READ MORE

3. Studies on the Load Range of an HCCI Engine using In-Cylinder Pressure, Ion Current and Optical Diagnostics
Abstract : Internal combustion engines are continuously developed towards decreased hazardous emissions and lower fuel consumption. The homogeneous charge compression ignition (HCCI) engine is a promising concept which combines the best features of the Diesel engine and the spark ignition (SI) engine. READ MORE

4. Characterization of an Electrical Sensor for Combustion Diagnostics
Abstract : The ionization sensor is an electrical probe for diagnostics in internal combustion engines. The combustion process affects the electrical properties of the gas in the cylinder. Thus the sensor signal contains copious information about the conditions in the combustion chamber. READ MORE
