Lube oil treatment for diesel engines

Protecting your engine, extending oil life

Diesel engines face tough conditions - and so does their lube oil. During operation, the oil is constantly exposed to contaminants like dust, metal particles, water, and chemical residues. These impurities speed up oil aging and can lead to increased wear and reduced engine performance.

Trunk piston diesel engines are especially vulnerable. Under partial load, unburned fuel and combustion residues can enter the crankcase. When these mix with water vapor, they form acidic compounds that can damage critical components such as bearings, pistons and cylinders.

The importance of effective lube oil treatment

Contaminated lube oil leads to increased wear, reduced engine efficiency and costly downtime. Regular and efficient treatment of lube oil is essential to:

• Remove solid and liquid contaminants
• Prevent corrosion and premature engine wear
• Extend the service life of both oil and engine components
• Reduce maintenance costs and environmental impact

Maximum engine protection with minimal effort

Centrifugal separation is the most effective and widely used method for lube oil treatment. In this process, a separator is installed in a bypass loop within the engine’s lube oil system. The separator efficiently removes water, sludge and particulate matter, ensuring the oil remains clean and fit for use.

For applications requiring 24-hour unattended operation, self-cleaning mineral oil centrifuges are the preferred choice. These systems automatically discharge separated contaminants, minimizing manual intervention and maximizing uptime.
