Unburnt fuel from the sac volume of a classical injector leads to incomplete combustion, which increases emissions and fuel consumption. This also forms increased combustion deposits in the exhaust gas system and piston running components, which may lead to extra maintenance costs for cleaning or component replacements.
The Fuel Activated Sacless Technology (FAST) reduces the amount of unburnt fuel and reduces fuel consumption. It improves the combustion quality significantly and lowers hydrocarbon and carbon monoxide emissions.
The FAST upgrade is available for all Wärtsilä 2-stroke engines with the following product reference type and specification:
