CRD Fuel Enhancer

From Cost Effective Maintenance:

Instructions how to clean and maintain diesel injectors:

Add CRD Fuel Enhancer to diesel fuel at 10mL per 80L. CRD Fuel Enhancer can be double dosed when:

• Injector feedback values are out of spec
• Badly worn injectors with a severe injector rattle
• Bad diesel fuel has affected vehicle performance

Additional Information:

The Common Rail Diesel (CRD) injection system is the most recent development to achieve ever more stringent diesel exhaust emission standards, but it is currently associated with widespread problems, including engine rattles, expensive injector and fuel pump failures, injector sticking, stalling problems and rapid piston and liner wear. Problems have been documented across a wide range of engine suppliers, including Toyota, BMW, Volkswagen, Nissan and many more.

Cost Effective Maintenance have specifically developed our fuel additive ‘CRD Fuel Enhancer’, to address rattles, and provide smooth operation of fuel pumps and injectors. Used routinely, it will increase the service life of fuel systems and minimize the potential for the above problems.

The CRD system requires a significant increase in operating pressure compared to earlier systems. Fuel system pressures of up to (and above) 30,000 psi are required, and combined with ultrafine tolerances of diesel pumps and injectors, achieve superior fuel atomization for cleaner combustion. There are several factors that place significant additional stress on this system, compared to earlier diesel injection systems…

1. The increased operating pressure causes higher loadings on equipment, and this places a bigger demand on the fuel’s lubricating ability.
2. The higher pressure causes much higher fuel temperatures, which can actually degrade the fuel, forming fouling deposits within pumps and injectors.  Such deposits interfere with the fine tolerances, to cause sticking, malfunction and injector wear. This risk increases if using biodiesel blends, since biodiesel by nature, degrades faster.
3. Diesel sulphur levels have been reduced, to reduce smoke emissions. However, sulphur provides lubrication, so lowering sulphur levels can result in greater wear to very expensive fuel pumps and injectors.
4. CRD engines are designed with much finer tolerances within pumps and injectors, as well as piston to liner clearances, making them much more susceptible to deposits, and also the presence of any water contamination in the fuel.

CRD Fuel Enhancer provides strongly enhanced fuel lubricity, superior deposit control for fuel pumps and injectors, and exceptional anti-rust/anti-corrosion protection. While it’s recommended as a routine preventative step for CRD engines, it has been shown to eliminate severe injector rattle, restore operating performance and economy. It is designed specifically for Common Rail Diesels, but is suitable for all diesel engines. It is not recommended for petrol engines.
