In-Depth Information
• Performance has been increased by 42%;
• Exhaust gas emissions have been reduced by more than 50%;
• Fuel consumption has been lowered by 15%;
• Smooth running has approached the standard of spark ignition engine technology;
and
• Maintenance has been reduced by about 50%.
The introduction of Self Diagnosis technology will contribute to improving fuel
injection, increasing the maximum injection pressure, optimizing spraying injec-
tion process, and controlling nozzle operation.
There are four further ways to be used for near zero emission combustion:
• Mixing the fuel and air homogeneously in the intake outside the combustion
chamber;
• Igniting fuel and air mixture with optimal compression;
• Avoiding soot formation by effective regulation of a lean combustion; and
• Burning fuel without flame in a porous inert medium, e.g., in a ceramic com-
bustion chamber.
Porous ceramic burners have an exactly defined structure of holes. Engines with
porous combustion chambers are still in the development stage. Particularly,
monitoring and regulating have to be developed to prevent backfires and special
flashbacks.
