Universal Diesel FADEC Dual-Channel Engine Control Unit for 2-8 Cylinder Engines Description SILVER ATENA’s Universal Full Authority Digital Engine Control (Universal FADEC) is designed for the control of common-rail Diesel engines with up to eight cylinders. Due to the large number of interfaces it is suitable for different engine concepts (e.g. 2-stroke, 4-stroke, Wankel, etc.). Different injection nozzles with up to 80 V boost voltage can also be operated through mounting options. The mechanical design enables an easy installation and cable management. The redundant architecture is designed for use in aircraft according to CS-23, rotorcraft according to CS27 and CS-29 as well as UAVs / OPVs respectively RPAS. With SILVER ATENA's autocode toolchain (SDE), an engine-specific control and monitoring software, created by using MATLAB / SIMULINK, can be easily and quickly integrated into the engine control unit. This control laws model is simply parameterizable on the test bench with standard tools such as INCA. Furthermore, the basic software already offers an extensive data and fault memory. Within a very short time SILVER ATENA’s Universal FADEC is ready for use for the validation of control and monitoring concepts. It can be certified and used as a series device in unchanged form. By removing unnecessary interfaces it can be optimized quickly regarding weight and cost. Redundant hardware architecture for controlling and monitoring a common-rail Diesel engine with single power lever control or dual channel bus connection to a Flight Control System or auto throttle. Dual channel FADEC architecture (full operation of aero engine also with only one FADEC channel) Easy Integration of an autocode generated engine specific control and monitor software model Developed according to civil aviation standards RTCA DO-178C (software) and DO-254 (hardware) with safety level DAL B (Design Assurance Level) Certified for environmental conditions according to civil aviation standard R
