Dutch researcher Bas Bougie has developed a laser-based system to measure soot formation in diesel engines.
Washington, December 9 : Dutch researcher Bas Bougie has developed a laser-based system to measure soot formation in diesel engines.
The turbulent environment in the combustion cylinder of a diesel engine makes the measurement of soot formation difficult. It is also difficult because the pressure at which fuel is injected in to the cylinder causes an extra source of turbulence.
Bougie has revealed that he made his measurements in a glass cylinder with an engine adapted for the purpose.
He says that Laser Induced Incandescence (LII) can be used to investigate optimal engine conditions that reduce soot emission from the engine. According to him, LII can be deployed in different types of engines and with different fuels.
Bougie said that he carried out measurements during higher and lower loading of the engine, and for two different fuel injection systems-a line pump system and a common rail system.
The researcher said that neither the engine load nor the injection system was found to affect the primary particle size of the soot emitted. However, there were many other motor settings that could lead to an improvement in the combustion.
Bougie's measurements can now be used to verify existing combustion models at Eindhoven University of Technology.
A consortium of researchers will study how further improvements can be introduced in the measuring system, so that the objective of producing cleaner diesel engines may be achieved.
