Preface of the 'Symposium on Nonlinear and Embedded Control Systems for Internal Combustion Engines'

摘要

In the recent years there has been demand for increasing the power that is produced from internal combustion engines (ICE) under variable operating conditions. There has been also demand for reducing fuel consumption and for operating engines at minimum cost. Moreover, EU and national legislations have imposed the reduction of polluting gas emission from these engines. To succeed these objectives it is necessary to develop and apply to internal combustion engines more elaborated control methods. Actually, to improve the efficiency of the internal combustion engines in terms of high power or torque and of low fuel consumption, the use turbo-charging has a positive impact. Turbo-charging enables also to design engines of lower volume where friction torques are significantly reduced. To succeed reduction of polluting gas emission, it is again important to use exhaust gas recirculation (EGR) and turbo-charging techniques. Additionally the use of variable valve timing control schemes can also help to increase the power that the internal combustion engine generates and to reduce the emission of polluting gases.
