Cat, Cummins, Mack & Detroit oil soot, carbon & blow-by issues

Diesel engine starting becomes increasingly more difficult as engine deposits build up over time, especially during cold weather. Types of operation, such as excessive idling, short run time, light work, and city type driving, all contribute to deposit formation which can result in less than satisfactory starting. All these operating conditions do not allow efficient combustion of the diesel (or gasoline). In addition, poor maintenance and general age will also contribute to deposit build up.

What causes engine power & efficiency to deteriorate?

Typically, deposits build up in several critical areas of the engine…

  • Injector tips. This prevents optimum fuel spray atomization, as well as distorting the spray pattern.

  • Cylinder glaze. This is a build up of very fine carbon particles which fills the cylinder cross hatching, making the bore glassy smooth and reducing cylinder compression and increasing blow-by. Good compression is essential for diesel engine starting, especially when the ambient temperature is low.

  • Piston ring deposits. This causes the rings to stick in the ring grooves, which also reduces crucial cylinder compression and oil control.

  • Combustion and exhaust deposits. Carbon build up in combustion spaces, especially on piston crowns, interferes with efficient mixing of the fuel spray with the air, and also decreases the effectiveness of the ignition flame. Exhaust deposits reduce the engine’s ability to breathe efficiently.

  • Sludge and gummy piston rings. Apart from increasing internal drag, which adversely affects engine cranking and efficient lubrication, loss of compression can be great, and oil control drastically reduced.

Rather than carrying out expensive mechanical work to physically remove, clean and replace affected parts of engines and fuel systems (an effective overhaul), all of the above mentioned deposit types can be removed by safe chemical means, and with minimal downtime. In fact, much of the clean up occurs during actual, normal driving.

How to restore & maintain engine power & efficiency

The products below have been proven over decades of use, and can be relied upon to restore maximum efficiency.

  • Cleanpower Fuel Treatment. Employing specific fuel system detergents, Cleanpower restores full cleanliness to fuel pumps, lines and injectors to correct distorted fuel spray patterns, and provide optimal fuel misting.

  • FTC Decarbonizer. This product is unique! When added to the fuel, it acts as a combustion catalyst to ignite fuel much easier during starting. It also literally burns off carbon from combustion and exhaust spaces at much lower temperatures than otherwise possible. So, even during adverse engine operating conditions, it burns off deposits such as cylinder glaze, combustion and exhaust deposits, even turbocharger deposits.

  • Flushing Oil Concentrate. Based on specific detergents designed for heavy deposits (rather than abrasive and corrosive solvents), pristine cleanliness can be restored to the whole oil wetted side of the engine at time of oil change. It removes stubborn sludge and hard damaging carbon type deposits to restore full available compression and clean, efficient lubrication to the engine.

  • AW10 Antiwear. This is recommended to add to the engine oil once the oil is restored to clean condition (after using Flushing Oil Concentrate). It significantly reduces frictional drag throughout all lubricated mating parts of the engine, and consequently reduces the battery’s cranking demand.
