The Bosch Electronic Diesel Control System for Medium and High Speed Engines
EPA Tier4, IMO Tier3 and EU3b emission limits require complex systems of fuel injection-, air- and exhaust gas treatment. The BOSCH control units for engine management in the commercial vehicle and off-highway are designed to meet the requirements of the legislation on further emissions. It is obvious to use this available technology for the medium and high speed engine applications. BOSCH is a leading manufacturer in the field of electronic fuel injection control and monitoring systems. Building on the success of the BOSCH automotive Engine Control Units and Sensors, BOSCH has derived an engine controller and a set of sensors for industrial- and maritime applications The commercial vehicle ECU SW and HW platform includes complex functions for fuel balance control, exhaust gas recirculation, exhaust gas treatment, multi fuel injection control, fuel pressure control, engine position management, engine speed governors, multi ECU systems and diagnostic functions, etc. which are the basis for the newly developed BOSCH maritime electronic diesel control platform. Modularity and flexibility of the ECU SW and HW is a key criterion to cover all medium and high speed engine variants optimum. Multi ECU systems for engine variants up to 16 cylinders (2 ECU’s) are available and up to 24 cylinders (3 ECU’s) in preparation. Common ECU SW with individual functions, e.g. twin air flow and fuel pressure control (left/right engine bank) for multi ECU systems are configurable in the SW build process. With SW sharing the customer can realize its own SW functions on the supplied ECU HW and SW platform. Homologation for the most important ship classification societies for the ECU and a set of common used engine sensors is in progress. Pre-Compliance Test’s have been performed and the final compliance test is in preparation. In Cooperation with BOSCH Rexroth an interface for the integration of the ECU engine control management system into the Rexroth ship automation system is developed. BOSCH becomes a supplier of remote-, propulsion-, alarm-, safety- and engine management systems for maritime applications. This technical paper will describe the BOSCH electronic engine management system components for the medium and high speed engine applications.
