Sammanfattning : .... LÄS MER
7. The Influence of Multiple Injections on Combustion : an Experimental Investigation
Sammanfattning : The high fuel efficiency and torque of the diesel engine has made it the obvious choice for heavy duty applications for a long time. In addition, these characteristics of the modern super-charged HSDI diesel engine also make it very suitable and popular for car applications. LÄS MER
8. MEASUREMENT OF PARTICULATES EMITTED FROM SGDI ENGINES
Sammanfattning : This thesis discusses particulate emissions from spray guided, gasoline, direct-injected (GDI) engines. The aim was to measure solid particulates without the influence of volatiles. Therefore, two sampling systems were developed for sampling either low or high particulate content. LÄS MER
9. In-Cylinder Fluid Flow, Fuel Preparation and Combustion in SI Engines - Application of Optical Diagnostics
Sammanfattning : In this thesis laser-based measurements of in-cylinder flow and fuel concentrations in two stroke and direct injected four-stroke engines are presented. The major problem with the carburetted two-stroke engine is the short-circuiting of fuel that occurs during the scavenging phase. This leads to large emissions of unburned hydrocarbons. LÄS MER
10. Combustion Sensing Methods - in Theory and Practice
Sammanfattning : 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. LÄS MER
