16. The Low Load Limit of Gasoline Partially Premixed Combustion (PPC) - Experiments in a Light Duty Diesel Engine
Sammanfattning : The decreasing oil supply, more stringent pollutant legislations and strong focus on decreasing carbon dioxide emissions drives the research of more efficient and clean combustion engines. One such combustion engine concept is Homogeneous Charge Compression Ignition (HCCI) which potentially achieves high efficiency and low NOx and soot emissions. LÄS MER
17. HCCI Combustion - Engine Operation and Emission Characteristics
Sammanfattning : The potential and limitations of the Homogeneous Charge Compression Ignition (HCCI) engine concept has been experimentally investigated. The operation range, in terms of usable air/fuel ratio and engine load, and the emission characteristics have been studied. An 1. LÄS MER
18. Experimental Investigations of Combustion Chamber Heat Transfer in a Light-Duty Diesel Engine
Sammanfattning : This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. LÄS MER
19. Experimental Studies of Advanced Ignition Systems for Lean Burn Natural Gas Engines
Sammanfattning : One of the greatest challenges for the transport sector today is reducing its environmental impact. This applies especially to the emission aspects, much due to increasingly stringent emissions legislations. LÄS MER
20. 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
