Cost Effective Maintenance presents a range of proven additives for managing common rail diesel emission control equipment.

Common rail diesel engines were introduced to meet the need for more stringent exhaust emission requirements. Fuel pumps, injectors, EGR valves, catalytic convertors and diesel particulate filters are all integral parts of the emission control system. Most of the problems encountered can be corrected and controlled with the correct use of quality, purpose designed additives.

Cost Effective Maintenance offers a choice of additives to manage various problems in common rail diesel engines.

Injector rattle and poor fuel economy

Injector response is impaired allowing over-fuelling and detonation rattle. Caused by system deposits and fuel lubricity issues, injector response in the high pressure/high temperature systems can result in diesel degrading in service, forming deposits and losing lubricity, and even leaving a black residue in fuel filters.

CRD Fuel Enhancer restores cleanliness and lubrication to pumps and injectors.

Sooty lube oil

Usually related to injector malfunction, sooty lube oil can overload the oil, resulting in sludge and piston ring sticking problems.

Full crankcase cleanliness can be restored safely using detergent based Flushing Oil Concentrate.

Coking of combustion and exhaust spaces

Poor combustion is also caused by injector malfunction, excessive short runs or light loadings among many reasons, allowing deposits to build up.

FTC Decarbonizer added to the diesel will actively burn off combustion and exhaust carbon.

EGR valve sticking

Caused by excessive exhaust soot and carbon build-up, the problem is exacerbated when inlet manifold deposits also build to alarming levels.

FTC Decarbonizer is used to burn off carbon and reduce exhaust soot production. When used regularly, it will keep EGR valves cleaner and functioning properly.

Catalytic Convertors and Diesel Particulate filters

These can become contaminated and restricted due to the upstream effects.

Regular use of FTC Decarbonizer will clean up and keep catalytic convertors and DPFs clean.

In conclusion, the neglect of any of the emission control components will have a negative and compounding effect on multiple components, necessitating a multi-faceted approach. Use of purpose-designed additives can be extremely cost-effective in correcting these problems.
