FID Injector - Water Fuel Emulsion to reduce emissions

Water Fuel Emulsion system (WFE) - FID Injector

WFE system
Emissions purification and combustion improvement system designed to create a stable “water in fuel” emulsion. The implementation of emulsified fuel significantly enhances fuel atomization and distribution in the combustion chamber. This results in more effective combustion, lower fuel consumption and a reduction of NOx, HC and PM pollutants, while the engine’s combustion chambers, pistons, exhaust system and lube oil will stay much cleaner. 

NOx reductions using water in fuel emulsions are significant; approximately 1% NOx reduction is achieved for every 1% injected water. Using existing fuel systems, water content is limited to 20%.The FID Injector has a cost advantage over other systems, primarily due to its simplicity in system installation and operation. With the better combustion your exhaust will stay cleaner. This will lead to cleaner wash water from scrubber systems.

The FID Injector (WFE) system is one of the simplest systems to reduce the particulate matter and soot emissions significantly. The system will target these emissions at the source, the fuel. 

Operational costs are low as the only major requirement to the Injector is the water addition. The FID Injector has a small footprint and all necessary components are available inside the frame. The FID Injector is installed between booster feed pump and mix tank to simply control the water injection.

Benefits from our Water Fuel Emulsions system:
Up to 2% fuel saving with a 4 stroke engine and 2,4% with a 2 stroke.
Less engine maintenance
Up to 20% NOx reduction 
Less black smoke
Up to 90% PM and Soot reduction
Assisting your ships scrubber system (keep the scrubber cleaner)
​Scrubber wash water will be cleaner

Water in fuel emulsion will create a better combustion

water in fuel droplet
  1. Water in fuel emulsion as it enters the cilinder
  2. When the air/Fuel mixture is compressed in the combustion chamber, the water starts to evaporate 
  3. The water turns to steam, in this proces the fuel droplets are atomized thoroughly
  4. The forming of steam and the thoroughly atomized fuel causes a better and more complete combustion of the fuel (more surface area of the fuel and more oxygen from the steam). The steam also reduces the peak flame temperature, thus reducing NOx.

The full fuel flow must pass through the FID Injector, the fuel flow is measured by a flow meter (1) and is constantly monitored (10)
The fuel passes through the F.I.D. (2) which mixes the water in the fuel.
The amount of injected water is a percentage of the fuel flow, when the fuel flow changes, the water flow changes with it. The amount of water has an upper limit, a higher value then the upper limit will not be accepted by the program. This upper limit will be programmed, default is 20%.
Fresh water is stored in the fresh water tank (4). The level of the tank is regulated by a automatic fill-valve (3). The water pressure must be higher than the fuel pressure to inject it into the fuel. This is done by a frequency controlled pump (5). This pump brings the water pressure 2 bar higher than the fuel pressure. The flow of the high pressure water is measured by a flow meter (6) and a PI-controlled regulating valve (7) regulates the amount of water that is injected. There is also a solenoid (8) valve to make sure the water stops when the fuel flow is to low or the FID Injector is stopped.
