Gas Engine Management: KRONOS 20

Extension of the KRONOS 10 system using a motor actuated gas valve and a digital electronic control unit with electronic mixture control.

The open-loop implementation allows the definition of desired ?-values, within specific limits, for the full operating range.

With the closed-loop implementation, it is also possible to compensate for disturbance variables using power feedback. This means that emissions limits can be complied with, with higher accuracy and under all operating conditions.

A closed loop version including a ?-sensor is available for providing ?1 operation with a catalytic converter.

Suitable for use with small to medium sized engines (up to 1 MW) that have increased requirements for control of the gas/air mixture.

Thanks to its flexibility, the open-loop system provides improved starting behavior, improved idle running, and better performance under load, for all engines.

The closed-loop system offers excellent long-term stability, and is suitable for use as a trimming system where variable gas quality is an issue, particularly in bio-gas, sewage gas, and landfill gas applications.
