Efficient optimization of heavy-duty diesel in compliance with emission standards
The main objective of this project was to develop a prototype of a highly advanced heavy-duty diesel engine having: - increased thermal efficiency; - a 30% lower emission standard against foreseen future regulations, and - the capability to operate efficiently, even with future lower-quality fuels. The targets of the engine optimisation are compliance with emission standards of R49-30%, and a thermal efficiency of 0.44. The concept is based on a better and more complete combustion to be promoted by a highly improved air-fuel mixture in the combustion chamber. This would allow low maximum temperatures and better utilisation of the in-cylinder trapped air to be achieved. The wide parametric experimentation, both on single cylinder engines (devoted to flame propagation studies) and on real truck engines, involved several experimental conditions for a variety of parameters. The experimental work was guided by the trends derived from the application of mathematical models.
