Fuel Systems

Condensation, poor fuel supplies, poor fuel storage and bad housekeeping all play a significant part in diesel fuel contamination. To overcome this all diesel powered equipment will be fitted with some form of fuel filtration system. This will vary in complexity from a simple in-line filter to highly complex water separation and combined multi-filtration and fuel conditioning system.

Whatever type of system is fitted it will have a number of drawbacks. It will have a limited capacity that requires regular monitoring and servicing and also it has to treat the fuel after it has left the fuel tank. FuelActive® is unique by approaching fuel contamination at the most important point “The Fuel Tank”.

Traditional systems draw fuel from the bottom of the tank. Due to their higher density, the water and contaminants will collect at the bottom of the tank. During refuelling etc; the water and contaminants will become agitated and drawn into the fuel system; over a period of time the filters/water separators will become saturated and the equipment will breakdown or cause damage to the fuel system components, this will increase the emissions from the engine and cause a reduction in power.

The diesel fuel system contains the finest tolerances found in modern, low-emission diesel engines.

The modern diesel engine fuel system operates at a significantly higher pressure than previously. Common Rail systems can operate in the region of 2700bar (40,000 psi), the high pressure allows the fuel to be atomised more efficiently and the benefits are lower emissions and improvements in power.

For the fuel pumps and injectors to operate and sustain their performance requires very clean fuel.

Durability

The Fuel Injector is designed to spray and atomise the diesel in a pre-determined pattern; this allows the diesel to burn correctly; this enables optimum power and keeps emissions to a minimum.

If the injector is damaged the diesel will not be atomised correctly, this can cause a number of problems: -

  • There will possibly be a breakdown of the equipment, resulting in expensive repairs and downtime
  • There will be an increase in the emissions because the fuel will not ‘burn’ completely; unburnt fuel will be passed through the exhaust into the environment as black smoke.
  • There will be a reduction in power because all the energy has not been utilised in the fuel.
  • There will also be an increase in Fuel Consumption; this is due to the engine working harder to achieve the same level of power.
