Abstract

The policy of reducing emissions in the energy sector is one of the scientific community’s main research topics. There have been significant developments in automotive and business fields, particularly in diesel engines. Nowadays, the method, which is widely used in reducing emissions of a Diesel engine, is the dilution factor called EGR through which it is possible to lower NOx levels. With the reduction of NOx also the performance of a diesel engine (e.g. the stable combustion and engine power) should be evaluated. This paper presents a useful methodology for analysing the change of the dynamic of the entire engine system, which is due to small changes in EGR dilution ratio. The adoption of systems with sophisticated signal processing such as the one presented in this paper, allows easier control of complex systems, such as diesel systems HCCI.
