SULZER RLA90-AN IMMEDIATE SUCCESS

The new Sulzer 6RLA90 prototype Diesel engine was recently demonstrated by Winterthur to an international gathering, together with a typical Sulzer bridge control system and a number of other engines. Use of the new BBC Series 4 high-pressure ratio turbocharger and relief under-piston scavenge air pumping at above two-thirds load have made a significant reduction in the fuel consumption, which is now 142 g/bhp referred to ISO 3046/1 conditions. The new engine is the largest of the long-stroke series and to enable it to be installed within limited headroom, the turbocharger module can be mounted off the engine to either end or above, in the casing. The piston-rod seats on the top flat of the crosshead pin and is attached by means of a set bolt instead of by a threaded tail passing through the pin. The 6RLA90 engine will be offered with from four to 12 cylinders.
