Strategy for intelligent internal combustion engine with homogenous combustion in cylinder

  • In this report the author proposes strategy for development of intelligent combustion systems with a goal to approach a near-zero emission internal combustion engine operating in a wide range of speeds and loads. Main requirement for future I.C. engine is to develop a system permitting homogeneous combustion process (minimum of engine emissions) under all operational conditions. The author suggests, that none existing individual combustion system may satisfy these conditions. However, combination of different individual combustion modes in a one system may permit homogeneous combustion in a wider range of loads. Such combination of individual systems having potential for a homogeneous combustion and operating in different ranges of engine loads is here defined as an intelligent engine. In order to make this strategy practicable a new concept for mixture formation (MDI-Mixture Direct Injection) and homogeneous combustion based on the Porous Medium (PM)- technology is proposed in this paper. This is probably first publication indicatingIn this report the author proposes strategy for development of intelligent combustion systems with a goal to approach a near-zero emission internal combustion engine operating in a wide range of speeds and loads.
