Fuel Water Emulsion

Fuel Water Emulsion (FWE) is a pre-treatment technology designed to lower fuel consumption and air emissions in diesel fired engines. FEW is an add-on circulation system, utilizing fully electronic controls and monitoring systems, designed to blend water with diesel fuel immediately before the fuel injection pump. The fuel is taken from the existing fuel supply system and pre-mixed with varying, previously specified amounts of specially treated fresh water. This pre-treatment allows customers to maximize the benefits of the unit, according to the desired output.
