THE ENERGY ENGINEERING COMPANY E²PRECON-c processes data from up to 20 cylinder pressure sensors and provides real-time combustion characteristics for monitoring and closed-loop control. With the E²PRECON family AVAT has pioneered cylinder pressure based engine control since 2006. The c-series offers comprehensive real-time cylinder pressure analysis in a compact size. E²PRECON-c supports a wide range of cylinder pressure sensors from various manufacturers. Using well-proven digital signal processing algorithms E²PRECON-c computes combustion characteristics for each cylinder and every combustion cycle. These are the key parameters engine builders need to implement advanced combustion control, monitoring and diagnosis. Incorporating thermodynamic models, E²PRECON-c calculates the net heat release rate (netHRR). From this, important combustion parameters such as heat release (HR), start, duration and center of combustion (SoC / DoC / CoC) are computed. Indicated mean effective pressures (IMEP), peak pressures and knock levels are also provided. Since cylinder pressure sensors have a limited life time, sensor health monitoring and signal plausibility checks are included. Your key to cylinder pressure based combustion control Enables balancing, misfire and knock detection Cylinder-individual combustion characteristics Service tool assists in engine diagnostics and optimization Library for Bachmann PLC included (others on request) E²PRECON-c is easily integrated into engine control systems and PLCs via CAN
