MAN's Newest Common-Rail Engine

As seen at the 2007 Miami International Boat Show, MAN has added to its line of common-rail diesels with the R6-550. The six-cylinder, 550-hp powerplant is the smallest in MAN's line of common-rail power that extends to 1,550-hp. Preliminary data supplied by MAN list the R6-550 at 1,984 pounds; that's an impressive power-to-weight ratio of 3.6 lbs/hp.

Like the rest of the MAN family of common-rails, electronic engine control is supplied by MMDS (MAN monitoring and diagnostics system): The 6.3-, 10-, or 15-inch TFT diagnostic-system displays show speed, oil pressure, boost pressure, temperature levels of coolant and oil, and calculate gph and other relevant operating numbers. MAN developed the world's first diesel engine between 1893 and 1897 with Rudolf Diesel, when they were known as Maschinenfabrik Augsburg.
