Crankcase Ventilation Upgrade: Marine Diesel Engine C280-12

The Challenge

A Caterpillar Power Systems dealer was looking for a reliable crankcase ventilation solution for an inland towing vessel. The solution needed to effectively capture oil mist and keep it out of the surrounding environment. This was an upgrade for two C280-12 marine propulsion engines. These engines would power the vessel on the inland waterways of the United States.

The Solution

Solberg worked closely with the Power Systems dealer to recommend installation locations and provide installation details. Solberg supplied its SME Series Advanced Crankcase Ventilation System. This included Solberg’s Recirculation technology specifically designed for the marine market. It is a self balancing system that requires no adjustments and has a built in bypass line to ensure no pressure build up in the crankcase. After calculating the crankcase blow-by and drawing on field tests, one unit would be required per engine. Two total units were provided. Solberg stayed engaged throughout the process to ensure a smooth installation and start up.


With constant communication throughout the entire project, the two Solberg SME units were successfully installed. They are currently running without any challenges. The high efficiency coalescing filter successfully captures the oil mist and drains it back to a Solberg waste oil console. The SME’s are run in an open configuration and provide clean, filtered air out to the waterway atmosphere.

The Product

The SME Series is designed and manufactured to be a high efficiency oil mist removal system. This system captures crankcase blowby oil mist and particulate emissions from turbo machinery and engines. Solberg’s SME series optimizes equipment performance, offers a safe and clean work environment, and reduces costly repairs and maintenance.
