MTU Series 60 engines for the marine market now feature a centrifugal oil separator that is 99 percent efficient at de-oiling crankcase ventilation gases. The oil-separation system prevents contamination of the turbocharger, and requires no maintenance throughout the life of the engine other than periodic inspection of clamps and hoses. This results in a reduction of the life cycle cost of the engine.
Compared to traditional oil-separation systems which require a cotton filter and are only 75 percent efficient, the centrifugal oil separator employs an 8,000 rpm centrifuge that eliminates oil and soot in crankcase ventilation gases.
â€œEliminating oil from crankcase ventilation gases helps control emissions,â€ said Steve Neil, senior manager of marine service technical support, MTU Detroit Diesel. â€œIt also increases the closed crankcase ventilation system efficiency of the Series 60 Marine engine. The owner can feel confident that his system is operating effectively even while requiring less maintenance.â€
The Series 60 Marine engine is a four-stroke diesel engine with direct fuel injection, turbocharging and charge-air cooling. It is widely used to power workboats, ferries, tugs and barges â€“ applications that require low fuel consumption, rugged and compact design and low maintenance. The centrifugal oil separator is available on new Series 60 Marine engines and as an aftermarket retrofit. Upgrade kits are available from local MTU distributors.
