  • Page 14: Operational Principle

    The volume flow rate of the E-LES gas valve depends on the gas mixer and its design. The indicated performance range is valid only if the gas valve design is done by HEINZMANN. For applications combined with other gas mixers the volume flow rate can be 50% lower.

  • Page 15: General Application

    A digitally controlled MAS like the HEINZMANN E-LES (digital lambda adjustment screw) that receives its inputs from a speed and load dependent map and reacts to gas pres- sure and mixture temperature variations, makes it possible to obtain an ideal gas-air mix- ture under all operating conditions.

  • Page 16: Additional Functions

    In an ex- tended closed-loop version it allows compensation for changes in gas quality and envi- ronmental factors. This makes it possible to use biogas with minimal emissions. Figure 1: KRONOS 20 System 2.7 Additional Functions • Engine Stop On activation of the digital input for engine stop, the gas valve will be completely closed in dependence of the parameter settings until the engine stops.

  • Page 17: Gas Train

    HEINZMANN recommends to attach the governor not to the engine but to the frame. The pressure governor is not included in the standard scope of delivery of the KRONOS 20 system. On request, it can be delivered by HEINZMANN or a specific pressure regulator can be recommended by HEINZMANN.

    13 Error Handling 13.1 General The HEINZMANN Digital Controls of the KRONOS 20 series include an integrated error monitoring system by which errors caused by sensors, speed pickups, etc., may be detected and reported. By means of a permanently assigned digital output the error types can be output via some visual signal.
