The challenge: contaminated and quickly ageing lubricant

The lubricant of marine diesel engines is loaded differently, depending on whether it is a four-stroke or two-stroke *). In principle, however, the entry of impurities into the lubricant is unavoidable: particles, water and blow-by gases enter the lubrication system as a result of combustion and wear processes, environmental conditions (temperature changes, climate zones, etc.) and during repairs and cleaning work. Impurities accelerate oil oxidation and additive degradation and cause early oil decay — even with high-quality and expensive lubricants such as synthetic oil. Since frequent refill and change intervals cost money and pollute the environment, efficient lubricant filtration and sensible fluid management are essential. Contaminated and rapidly aging lubricant has a serious impact on operational safety, availability, cost-effectiveness and sustainability of ship operations.

*) The lubricant of four-stroke engines is usually more heavily loaded because there is only one lubrication system and combustion residues quickly contaminate the entire lubricant source. Two-stroke engines, in comparison, have two separate lubrication systems — one for bearing lubrication and one for cylinder lubrication. Thus, combustion residues do not contaminate the entire lubricant source, and the lubricant for the cylinders remains clean (loss lubrication).

Damage and consequences caused by contaminated and rapidly ageing lubricant

The lubricant temperature of typically 50-90 °C already intensifies oxidation processes and the degradation of antioxidants, but impurities such as wear particles (Fe, Cu, Al, Zn etc.), soot and water accelerate these processes many times over. Important additives such as wear and corrosion protection additives, detergents and dispersants, and acid-neutralizing additives are consumed much faster. Emulsified water washes the additives out of the oil.

The degradation of the base oil and the additive depletion means that the viscosity and acidity of the lubricant increase and the lubricating effect can be lost. Aggressive acids, due to blow-by gases, intensify acidification. The ingress of blow-by gases is inevitable whether you’re running the marine diesel engine with heavy fuel oil, marine diesel or gas oil, distillates, blended or residual fuel grades, dual-fuel or natural gas (LNG).

Therefore, for lube oil filtration, you should rely on a solution that removes all impurities — particles, water, oxidation products and acids.

oil ageing, oil oxidation, viscosity change

Water enters the lubrication system through leakages in the cooling system, by condensation, engine cleaning or centrifugal L.O. separators. Water in the lubricant damages metal surfaces (corrosion, rust and micro pitting) and accelerates oxidative processes and additive degradation. Abrasive rust particles damage surfaces and moving components and block narrow passages.

If cylinders and cylinder guides corrode, antifreeze also enters the lubrication system – immediate consequences for the marine diesel engine: increase in viscosity until the oil is wasted, poor flow and narrowed passages (lack of lubrication), clogged inline filters, deposits and an increased risk of foaming.

Water in combination with acids has a highly corrosive effect.

For lube oil filtration, you should ensure that your system also removes dissolved water, not only the emulsified water.

The sludge-like and varnish-like residues produced caused by oil oxidation preferably deposited in the marine diesel engine on valves, coolers, inline filters, bearings, internal boreholes, pipes and oil pan or circulation tank. Poorly controllable valves, changed lubrication gap geometries, decreasing effectiveness of the heat exchanger, clogged inline filters, and reduced flow (lack of lubrication) are the consequences. Reduced cooling capacity of the piston and heat exchanger can lead to severe engine failures.

During fuel combustion, also soot particles enter the lubricant. With increasing content and decreasing additives, they agglomerate, fall out and deposit throughout the system. The result is time-consuming cleaning and flushing as well as reduced engine power.

Your solution for lubricating oil filtration should be able to maintain the lubricant’s dispersancy as long as possible and slow down oxidation processes.

Particles cause excessive wear and damage to bearings, cylinder liners, piston rings and all oil-lubricated components. In particular, particles of 3—10 μm cause the most significant damage and block narrow passages such as camshafts, pins/bearings, cylinder liners and piston rings. Due to the increasingly narrow tolerances and higher pressures, you should attach importance to a corresponding filtration degree for lube oil filtration.

wear, marine diesel engines

Contaminants, oxidation residues and an increased viscosity impair the air release property. Air bubbles in the engine oil entrain poorly, and the risk of foam increases resulting in a lack of lubrication for engine components.

Existing oil filters clog rapidly because of the low dirt holding capacity and must be changed frequently.

The conventional method

To ensure the reliable operation of the marine diesel engine, the crew regularly checks the condition of the lubricant. When a critical value is reached, they partially replace the lubricant or change the oil completely. However, this does not reduce the load on the lubricant. On the one hand, the newly filled-in oil contaminates within the shortest time due to deposits and dilution with dirty residual oil. On the other hand, impurities, oxidative processes and acids unhindered strain the lubricating properties and the long-term effect of additives, which shortens the service life of the oil filling. That finally results only in high oil consumption. With us, however, this is more ecological and economical.

CJC® Lubricating Oil Filter vs Centrifuges

Due to the enormous savings potential in terms of operating and energy costs, and the lower lubricating oil losses, the CJC® Lube Oil Filter amortizes within the first two years of operation despite the additional installation costs when retrofitting and replacing the centrifuge.

Briefly explained in our video — take a look for yourself

Did you know that by installing a CJC® Lube Oil Filter you …

  • consume up to 60% less lubricant,

  • have to dispose of approx. 99% less oil sludge,

  • consume about 97% less energy for oil care,

  • generate up to 96% less CO2 emissions and

  • significantly saves operating and maintenance costs?

And that you also achieve much higher oil cleanliness?

  • The centrifuge only removes particles and emulsified water, but we also remove dissolved water, oxidation products and acids.

  • We do not introduce flushing water into the lubricant as with centrifuges.

In addition, even easier to install and operate:

  • Space requirements are precisely like a centrifuge

  • No preheating incl. pipelines are necessary

  • No control air (valves) are necessary

  • No water connection is necessary

  • Recurring inspections are no longer necessary

  • Simple operation without personnel requirements

  • No cleaning work is necessary, and thus means, less water consumption

  • Low maintenance; only filter inserts need to be replaced

CJC® Lube Oil Filter for the care and filtration of lubricants

CJC® Lube Oil Filters ensure maximum oil cleanliness — they easily exceed the recommended cleanliness classes of the engine manufacturers. Achieve the highest level of protection for your oil filling and marine diesel engines quickly, long-lasting and cost-effectively. Rely on world-renowned solutions with documented field results in engine lube oil filtration for over 70 years.

The integrated pump enables the installation in a separate circuit and, therefore, continuous depth filtration and care of the engine oil (24/7). The filter inlet is connected diagonally to the oil sump, and the filter outlet is connected higher up — as far away as possible from the filter inlet. The operation, filter insert replacement and maintenance are independent of the engine operation.

The CJC® Lube Oil Filter removes all impurities:

Oxidation residues and acids

for persistent stable oxidation rate, TAN and TBN

Wear particles, soot and insoluble

for the highest oil cleanliness

Water – free, emulsified and dissolved

for water content well below the saturation limit of the oil

Due to their variety of combinations and modular design, the CJC® Lube Oil Filters and the integrated CJC® Depth and Fine Filter Inserts can be optimally adapted to the specific conditions of the different marine diesel engines, independent of the fuel you use.

CJC® Fine Filter Inserts are depth filters with a filtration degree of 3 µm absolute and a retention rate of < 1 µm. The whole volume of the insert is made of numerous finely ramified fibres and offers an outer surface and, in addition, an inner surface – from 120 up to 150 m² per gram. That enables the extremely high dirt holding capacity – the higher, the longer the lifetime of the filter inserts.

The fact is that our dirt holding capacities are market leaders.

CJC® Lube Oil Filters are equipped with sensors for the automatic online monitoring of the filter condition (filter pressure). Up to three additional sensors for oil humidity, temperature and oxidation are implementable by default. You can configure alert limits and warnings to prematurely detect deviations from normal conditions and counteract them.
Optional further sensors can be supplemented to get more information about the oil condition. They deliver detailed data in real-time and allow conclusions about the engine condition because of the high data density.
Our intuitive operable cloud applications have a clearly-arranged dashboard to visualise the sensor data. The highly developed algorithms integrated into the premium monitoring package automatically evaluate and interpret the data — ideal for critical marine diesel engines where failure quickly results in unplanned, costly dock times.
