1. Particulate Emissions Associated with Diesel Engine Oil Consumption
Sammanfattning : Particulate emissions from diesel engines have been a key issue for diesel engine developers in recent decades. Their work has succeeded in reducing the exhaust particles from the combustion of fuel, which has led to increasing interest in the contribution of particulates from lubrication oil. LÄS MER
2. Minimum Quantity Lubrication
Sammanfattning : .... LÄS MER
3. Oil-related Particle Emissions from Diesel Engines
Sammanfattning : In recent decades much effort has gone into reducing particle emissions in the exhaust gases of heavy-duty diesel engines. Engine development has now reached the stage where it is worth to put heavy focus on the contribution of lubricating oil to particulate emissions in order to further reduce these emissions. LÄS MER
4. Properties of oil and refrigerant mixtures : lubrication of ball bearings in refrigeration compressors
Sammanfattning : A refrigeration compressor contains highly loaded mechanical contacts that have to be lubricated. The lubricant used in refrigeration compressors consists of an oil and refrigerant mixture, and the refrigerant concentration can be up to 40 wt%. LÄS MER
5. A Surface Engineering Approach to Reduction of Frictional Losses of Heavy Duty Diesel Engines
Sammanfattning : Reducing emissions is a top priority within heavy duty diesel engine development and research. The aim of the work is to decrease the fuel consumption by decreasing frictional losses of the Power Cylinder Unit.Full scale testing of engine components improvements is time-consuming and costly.
