This was mainly driven by improved availability and lower price of such alternative fuels ( i.e. Natural Gas ). Meanwhile have this Dual-Fuel and Gas engines proven their robustness in all major stationary Large Engine applications and tests on mobile applications are under process. ( i.e. Locomotives ) The extended system demands, pushed by upcoming emission legislation and fuel flexibility needs, will be supported by a new Bosch Large Engine specific engine control unit (LE-ECU). It will support the stable trend towards electronically controlled Fuel Injection Equipment (FIE) for Diesel, Gas and Dual Fuel engines. The LE-ECU is based on Bosch´s latest automotive control unit technology (MDG1) incl. a new powerful microcontroller generation and an AUTOSAR 4 compatible basis software. This LE-ECU extends the application spectrum of the already available marine certified ECU, which is mainly used in small high speed diesel engines, towards more complex engine applications and provides increased performance and scalability for current and future customer requirements. Corresponding to the market requirements Bosch already offers a broad and acknowledged Diesel-FIE portfolio (electrical Unit-Pump-System, modular Common-Rail-System). In combination with a modular set of Gas Admission valves, which is close to production, Pilot Injection-capable Injectors and field-proven sensors the LE-ECU allows the application and calibration of future Dual Fuel and Gas Engines. This paper gives an overview on the requirements considered for the specification of the control unit and how it fits to the existing FIE portfolio of Bosch for Large Engine applications. We will describe the system approach of Bosch for Diesel, Gas and DF engines, including all main components, to support the applications from small truck-derivative Large Engines up to medium speed engines used for Marine, Rail or GenSet applications.
