ArenaRed

Smart Combustion Technology

Electronic Computing Unit

 

The CPBC is fundamental in ArenaReds technology and uses uniquely designed Combustion Pressure Sensor (CPS) and Engine Control Unit (ECU). The combustion diagnostics extracted from every cylinder is used as feedback for the actuators, therefor the ECU requires a substantially amount of computing power to process the data coming from the CPS’s.

In order to provide quick demonstrators for new or other customers the DOCAT 3500AR ECU is built as an engine laboratory tool. It has 16 peak hold injector drivers. Its capable to drive any kind of injector, solenoid and piezo injectors. The ECU is fitted with extra in- and outputs for additional peripherals. Our ECU is also developed for acting as an engine lab data acquisition system.

The ArenaRed Chip is based on a Field-Programmable Gate Array (FPGA) with 8.000.000.000 programmable transistors. Only this kind of FPGA’s are able to run 1000 CPBC processes in parallel. The FPGA gives ArenaRed an enormous amount of control possibilities. This makes it possible to integrate functionalities from other devices too, when saving a controller can be an issue for saving cost. Integrations could be;
  • Control of the Gas Supply
  • Gearbox
  • ORC
  • Trip planning

ArenaRed is ready and able to convert the dedicated ArenaRed CPBC FPGA into a dedicated chip.
