Misfire Detection & Knock Control

In order to optimize the efficiency on modern gas engines, compression ratios are increased while the air-fuel ratio is becoming leaner. As a result, knocking or misfiring may occur - both harmful to engine components and spare parts.
With the control systems ARIADNE Knock Control and KASSANDRA Misfire Detection, HEINZMANN offers solutions for the protection and safe operation of modern gas engines.
Please also refer to HEINZMANN's >> Gas Engine Management Catalogue for details on all components.
