Popis: In order to meet future emission standards for gasoline vehicles, several complex approaches have been developed in the recent past by original equipment manufacturers (OEMs). A dual-injection system, which has a combination of a port fuel injection and a direct injection, is counted among these increasing numbers of complex developments for which new and extensive software implementations are required [1]. Bosch Engineering GmbH has developed a software control in the Bosch Engine Management System (EMS) ME17 for a dual-injection system with the main challenge of meeting future emission standards. Whereas each single-injection system is well-known and established in its individual use in a vehicle and its corresponding software implementation, the combination is still rarely available, much less with the increased emission limits of future emission standards (EU6 and later). While a port fuel injection offers better fuel management compared with a direct-injection system, the advantages of a direct injection have to do with responsiveness and overall fuel efficiency [2]. Compared with the previous emission standards, the amount of particles is significantly reduced in the EU6 limits and will be more decreased in the EU6c limits from 2017 on. This strict emission request has not been reached before with a dual-injection system. The following shows how to solve this challenge in the software system.
