Electronic System for Lambda Control
HEINZMANN KRONOS 20
HEINZMANN KRONOS 20 is an electronically controlled air-fuel mixture control system designed to adjust lambda values based on engine speed and load, in order to achieve optimal engine performance under all operating conditions.
In the various closed-loop versions, engine power, lambda, or NOx sensors can be used as feedback signals to automatically correct for fluctuations in gas quality and engine load.
Key applications include natural gas and biogas engines supplied via a zero-pressure regulator.

Description
The KRONOS 20 AFR control unit*) is a component of the KRONOS 20 system for electronic control of air-fuel mixture formation, in which lambda values can be set within a specific range depending on engine speed and load. This optimizes engine performance under all operating conditions.In a closed-loop control system, the lambda values are adjusted using a power signal or an exhaust gas sensor. Step sensors, wideband sensors, and NOx sensors can be used. Fluctuations in environmental conditions (e.g., gas quality and gas pressure) are fully compensated for.*) AFR = Air-Fuel Ratio (= lambda coefficient, i.e., the ratio of gas to air)
