1. Perception of rolling noise
Sammanfattning : Due to improvements on combustion-engines and electric-engines for cars, tyre noisehas become the prominent noise source at low and medium speeds. Models existthat simulate the noise produced by a rolling tyre, as do models that auralize differenttraffic situations from a basic data set. LÄS MER
2. On the Combustion Characteristics of Closely-Coupled LD Diesel Injection Strategies
Sammanfattning : Multiple-pilot injection strategies with both moderate and short time separations (dwells) are investigated in a light-duty diesel engine. Both conventional and optical engine experiments are performed. LÄS MER
3. AURALIZATION, PERCEPTION AND DETECTION OF TYRE–ROAD NOISE
Sammanfattning : Due to improvements in combustion engines and electric engines for cars, tyre noise has become the prominent noise source at low and medium speeds. Models exist that simulate the noise produced by a rolling tyre, as do models that auralize specific traffic situations from a basic data set. LÄS MER
4. Development of Multi-Dimensional Laser Techniques for In-situ Combustion Diagnostics
Sammanfattning : Multi-dimensional, laser-based measurements of quantities important for obtaining a better understanding of combustion processes, particularly of temperature and of species distributions, were performed using laser-induced fluorescence (LIF). The main purpose of the temperature experiments was to investigate the potential of employing a two-line atomic fluorescence technique (TLAF), using indium as the tracer species, in sooting environments such as in diesel engines.

5. Turbo Charged Low Temperature Combustion - Experiments, Modeling and Control
Sammanfattning : Both the global economy and the society in general are dependent on the availability of reliable transportation. Most transportation technology involves the use of internal combustion engines in one way or another. LÄS MER
