Cost Effective Maintenance
recommends FTC Decarbonizer and Flushing Oil Concentrate (FOC) for avoiding engine problems arising out of high oil soot.
Crankcase sludge, piston ring sticking, high oil soot levels, blowby, exhaust valve and turbocharger failures, and high oil burning are often inter-related problems encountered by transport operators. Early corrective action is essential as severe levels of sludge and carbon will eventually destroy an engine.
Any engine type can develop these expensive problems depending on the circumstances. For example, Detroit Series 60 owners routinely complain about high oil soot levels and severe sludge. In most of these cases, crankcase blowby, oil consumption and power loss are also reported, indicating that piston ring fouling has taken place. Mechanics are known to recommend the engine to be rebuilt in such situations.
However, products such as Flushing Oil Concentrate and FTC Decarbonizer are effective in restoring full serviceability to such engines by physically removing sludge and carbon, saving customers the cost of an engine rebuild, plus downtime losses.
Even owners of modern, low emission diesel engines including Cummins M11s and some Macks have complained of similar problems. Caterpillar 3500 Series users report increased incidence of severe carbon accumulation on piston top lands and exhaust valves in addition to higher oil consumption rates and severely shortened engine life. Flushing Oil Concentrate has been recommended at each oil service period to restore and maintain piston/ring cleanliness and oil control.
Complaints of high oil soot levels have been raised for most engine manufacturers including Caterpillar, Mack, Detroit, Cummins, Toyota, Nissan, Volvo, Scania and more. Soot causes several problems in the engine including exhausting the oil detergency so that engine deposits cannot be controlled.
Soot is also abrasive and increases wear on all lubricated moving components including bearings, journals, crankshafts, camshafts, piston rings and grooves, liners and valve rockers, causing many engines to wear out far too early. Use of FTC Decarbonizer in the fuel directly reduces soot production by combustion catalysis, lowering oil soot levels and also reducing the size of the abrasive soot particles.
High soot levels deplete the oil’s detergency reserves causing sludge to build up and carbon to deposit around piston ring grooves. Blowby and oil burning cause further carbon deposits to form in combustion spaces, piston top lands, exhaust spaces, exhaust valves and turbochargers, progressing to a catastrophic engine failure.
Cost Effective Maintenance offers the right solutions to rectify engine deposit problems ranging from heavy combustion, exhaust space carbon and injector fouling to severe crankcase sludging. Bore polish, valve failures and broken rings are common end results of such deposits, which if addressed early can be corrected to avert the damage while eliminating hard engine carbon and sludge.
Cost Effective Maintenance recommends a threefold action to correct and control the oil soot problem, which comprises of removal of deposits, reduced rate of migration past the rings into the crankcase, and reduced soot production rate.
Removal of deposits
Cost Effective Maintenance’s FOC offers effective action in the removal of soot or sludge residing in the crankcase so as to provide full available service life to the oil. Formulated with specific detergents that target hard baked-on carbon and persistent sludge, FOC is introduced into clean, hot crankcase oil, and operated at a fast idle for about 30 minutes, re-suspending the sludge and hard carbon deposits so that full cleanliness is restored to the crankcase. These contaminants are drained to provide full available service life to the oil.
FOC also helps restore full available compression control and oil control. FOC has a 20-year history of restoring crankcase cleanliness to chronic high soot engines and grossly sludged engines, and freeing up badly stuck piston rings.
Reduced migration past the rings
A clean and effective piston ring seal needs to be maintained with FOC to ensure minimal migration of combustion bi-products (including soot) into the oil.
Reduced soot production
Soot production rate can be reduced by restoring lost compression through piston ring clean up, and restoring fuel system cleanliness/injector spray patterns. FTC Decarbonizer is effective in achieving excellent results as well as further improving fuel mist atomisation upon injection into the combustion chamber, which assists in removal of existing deposits in combustion and exhaust spaces.
Deposit removal combined with lower soot production and improved piston ring sealing result in less oil soot loading.
