Common Rail Diesel Injection Engine Controller (CRDI) ECU

SEDEMAC offers India’s first indigenously developed CRDI (Common Rail Diesel Injection) ECU. CR-ECU controls an electrically operated injection system, which significantly improves the efficiency, minimizes Noise-Vibration-Harshness (NVH) and emissions over the conventional mechanical injection systems. CR-ECUs run highly complex control algorithms to ensure that the engine runs clean and efficient, in the full operating regime. These ECUs are customizable and scalable according to the customers' engine specifications and applications. The customers get the flexibility to develop their own high-level application layer logic, which will in turn reduce development times.

SEDEMAC’s CR-ECU controls a multitude of actuators including the injectors, to provide torque throughout the required RPM range, and at the same time it meets the new stringent emission norms. CR-ECU also interfaces with the relevant vehicle sensors which provide precise input for the timing of operating the injectors as well as other actuators; for example EGR valve, fuel metering valve, vane gates, etc.


  • A common-rail diesel engine features a high pressure (up to 3,000 bar) fuel accumulator, called the common rail. This accumulator feeds solenoid or piezoelectric injectors, which in turn inject atomized fuel, with precise timing and quantity into the cylinder. This precision is enabled by the Engine Control Units(CR-ECU)
  • SEDEMAC offers CR-ECUs for LCVs, MCVs and HCVs, for 2/3/4/6 cylinder common-rail Diesel injection engines
  • SEDEMAC CRDI ECU are BSIV ready and can be scaled-up to meet to BSVI norms
  • These ECUs incorporate all required functionalities, including pre/post injection, Exhaust Gas Recirculation (EGR), environmental corrections and CAN communication, etc.
  • There is provision of features such as idling start-stop, gear-based low-idle governing, etc.
  • SEDEMAC provides a wider application support for its ECU, its natural progression towards IoT and automation tools, makes it a preferred choice for commercial vehicles, passenger cars and diesel power gensets.
