Lecture “Diesel Fuel Injection Technology”;

Environmental protection is as matter of high priority is getting into focus on various levels over China. The Central Government puts emphasis on continuous improvement of all emission related technology. Especially in the automotive transportation sector the technology upgrade from outdated diesel combustion technology towards an environment friendly diesel technology, featuring electronic controlled direct injection engines, is obviously being driven by the introduction of CN4 emission norm. This trend of further emissions reduction will continue thus being supported and enabled through the new electronic controlled direct injection systems towards even more stringent requirements, outlined in CN5 and EU6 emission norm. Apart from the reduction of the emission limits, the testing procedure itself has a significant on the definition of the entire engine-combustion-system setup featuring subsystems such as air system including boosting and cooling, fuel injection strategy, combustion system layout and exhaust gas after treatment.

An important factor in the entire process of sustainable implementation of environmental friendly technologies such as Common Rail fuel injection, is the optimization of total system costs, especially keeping fuel consumption at its minimum level. During the course of this presentation, various approaches of fulfilling CN4 and beyond emissions will be presented analyzed and evaluated. As an overall trend a high flexibility of all engine subsystems can be seen as major requirement to balance best performance and emissions of an engine throughout the entire operating range. Key to the solution towards this requirement is the engine management system as “brain” of the engine, controlling and managing not only the fuel injection system but also coordinating and integrating all performance and emission related engine subsystems.

To serve the Chinese OEMs with the latest fuel injection technology, Weifu and Bosch founded the joint venture RBCD in 2004. Due to the localization of components, development and engineering, RBCD is well prepared to support the Chinese OEMs fulfilling all upcoming challenges of the further Diesel market development.
