AWVT THE ENERGY ENGINEERING COMPANY E2KNOCKCON-cE2KNOCKCON-c is an extremely compact anti-knock controller for up to 20 cylinders with a variety of extra functionality. The c-series of the E2KNOCKCON family offers in a compact size reliable knock detection and anti-knock control with high sensitivity. Up to 20 sensors for structure-borne sound are mounted on the engine and connected directly to E2KNOCKCON-c. Sophisticated digital signal processing algorithms filter the knock information reliably even under challenging acoustic conditions. E2KNOCKCON-c computes knock levels and ignition timings for each engine working cycle and transfers them to the engine control system or to the ignition system directly. But there is far more useful data in structure-borne sound than that. E2KNOCKCON-c reliably detects misfiring with no extra sensors and considerably faster than other methods. In combination with E2SERVICE the number and the maximum value of the knocking events as well as the number of misfires within the last 5 and 50 operating hours are displayed cylinder-individually as chart and spreadsheet. Affected cylinders will be detected instantly and thus maintenance activities can be planned efficiently. E2KNOCKCON-c is easily integrated into engine control systems and PLCs via CAN bus. • High sensitivity and selectivity • Cylinder-individual knock detection and anti-knock control • Reliable misfire detection • Misfire and knock statistics in clearly arranged form • Direct communication to Motortech MIC3+, MIC4 and MIC5 ignition systems • Library for Bachmann PLC included (others on request)
