SOOT BUILD UP CAUSES DAMAGE
Soot build-up on internal engine parts leads to more maintenance
Container vessel Caronia is propelled by 2 ABC engines type 6MDZC. Since the beginning the engines have even been running on conventional SAE 30 mineral lubricant.
Upon close inspection, and 40,000 running hours, significant soot build-up was found. The internal parts of the engine were black.
Soot is a problem that particularly affects diesel engines, as combustion is less efficient than in gasoline engines. Individual soot particles are small and relatively harmless, but in higher concentrations they start to clump together.
Concentrations of soot will thicken lubricants and affect their viscosity, making them less effective and forcing engines to work harder. Soot contributes to the formation of varnish and carbon deposits, causing wear and ultimately reducing the engine’s power and efficiency. When excessive soot collects it can form a congealed mass called sludge, which is a leading cause of diesel engine failure.
Benefits
Exceptional thermal and oxidation stability, antiwear properties
Outstanding performance at high and low temperatures
Lubricant analysis can reduce downtime by giving you data on the performance of your oil and equipment so you know when maintenance is needed
The SOLUTION
An advanced lubricant with strong cleaning properties
Choosing the right lubricant is essential for combating soot. While soot formation cannot be altogether prevented, the right lubricant formulation can prevent the particles from clumping together.
On the advice of their authorised Mobil distributor, Caronia switched to Mobilgard™ ADL 30.
The Mobilgard ADL Series is a family of high-performance, increased-dispersancy engine oils for medium and high-speed engines. Its precise balance of detergent and dispersant properties enable these oils to provide resistance to lacquer formation and assist in sludge and deposit removal.
The IMPACT
A cleaner, more efficient engine
Use of Mobilgard ADL 30 conveys a range of benefits. It avoids the high oil consumption associated with cylinder liner lacquering, while its superior load carrying properties minimises piston ring and liner wear.
By keeping the engine clean, there is less internal wear, less maintenance required, and engines can be kept running longer.
Subsequent visual inspection of the Caronia’s engine confirmed the its improved engine cleanliness.
