leanoxCombustion technology
LEANOX is a lean-mixture combustion control. It was developed by Jenbacher and has been patented worldwide.

The system ensures the correct air to gas ratio under all operating conditions. This has the benefit of minimising exhaust gas emissions whilst maintaining stable engine operation.


The LEANOX system uses a special combustion chamber configuration for more efficient combustion and directly links power output, boost pressure, fuel temperature and nitrogen oxide emission. This eliminates the need to monitor oxygen in the exhaust using a Lambda probe.

The LEANOX control system corrects engine parameters to ensure the engine permanently meets the required nitrogen oxide emission level.
