Experimental Investigations of Combustion Chamber Heat Transfer in a Light-Duty Diesel Engine
Author
Summary, in English
Hot exhaust gases could be more useful than hot cooling media, because that heat may be extracted and used to improve engine efficiency. This reduces fuel consumption, and consequently emissions of greenhouse gases, which contribute to global warming. The world energy demand is still increasing, and more natural resources are being used. Higher efficiency requires less fuel, and thereby reduces the impact on environment and humanity.
The work was performed in a 4-cylinder light-duty diesel engine. Temperatures and mass flow measurements were performed in cooling media and exhaust gas. From these calculations were executed to find out the heat fractions emitted to each medium. Two combustion chamber geometries and three injectors were tested and compared with respect to their impact on combustion and heat losses.
