2.1 System Characteristics
• Affordable and trustworthy electronic Lambda control system
• Improved starting, idling, synchronizing and load behaviour
• Freely parametrizable, load and speed dependent mixing ratio map
• Cold start enrichment possible
• Easy adaptation to different engine and gas types, requiring only minor parameter
modifications
• Only three sensors are required accordingly simple installation and reliable operation
• Simple and easy parameter setting and diagnosis with HEINZMANN
DcDesk 2000 communications software
Optional:
- Communication with handheld programmer HEINZMANN HP-03
or the optional integrated programmer
- CAN communication
• Extends application range of existing gas mixers mixing inserts therefore may be used
for different gas qualities within a certain range
• The mixture control systems as a trimming system is largely self-regulating on basis of
Bernoulli’s Law, thus avoiding constant movement of the regulating valve, to best ad-
vantage of control stability.
• In case of error, the mixture control system can be operated by hand in the conventional
way.
• The closed-loop version may be regulated via the power signal, an oxygen sensor or via
a CH
4
signal.
• Optional misfire detection is possible.
2.2 Applications
• Lean-burn engines
• Lambda 1 engines
• Stationary engines and vehicles
• Engines with fixed and variable speed
• Fuels: propane, natural gas, sewage gas, landfill gas, carburetted hydrogen vapour
• Fuels with changing gas quality
