A dual fuel engine system and method of operating the engine reduces emission rates of pollutants. The dual fuel engine includes a fuel oil supply connected to the engine and a fuel gas supply connected to the engine. Means connected between the fuel oil supply and the engine inject low levels of diesel fuel into the engine. In particular, the injection of diesel fuel is limited to pilot injection quantities only. The exhaust emission of NOx is maintained at less than 1GM/HP-HR, where natural gas is used as the primary fuel, and less than 0.5 GM/HP-HR where digester gas is used as the primary fuel. |
