Sulzer DM Engine Tuns This year is the centenary of the Sulzer diesel engine. On June 10, 1898, the first diesel engine built by Sulzer Brothers began running on the test bed in Winterthur, Switzerland. Since then, the Sulzer diesel engine has become a household name in the marine industry, and has passed through an amazing range of devel- opment, starting from the first engines — derived from the 1898 experimental four-stroke engine of 20 bhp — to the 90,000 bhp 12-cylinder RTA96C ship propulsion engine that recently entered service. A total of some 37,000 Sulzer diesel engines, aggregating 158.3 million bhp, had been built or were on order by the end of 1997. Formation Of Early Diesel Roots The remarkable association of the Swiss firm Sulzer Brothers with the diesel engine stemmed from 1879 when at the age of 21, Rudolf Diesel came to the firm's Winterthur works for work- shop experience after studying in Munich. In 1893, when he was seeking backing to develop his new engine concept, he sent a copy of his book Theory And Design of An Efficient Heat Engine As The Replacement For Steam Engines and Today's Known Combustion Engines to Sulzer Brothers. He also corresponded with Wilhelm Zublin, chief engineer at Sulzer Brothers, to promote his engine but with no suc- cess. At that time, the firm was enjoying tremendous success with its world-renowned HALEY CLUTCHES t^EARS] COUPLINGS 800-6,000 HP Range • Ratios From 2:1 UpTo 10:1 Able To Match Existing Foundations With Custom Designs HALEY Clutches & Couplings Complete The Perfect Package HALEY Rl2828 PNEUMATIC CLUTCH MARINE GEAR L HALEY DRI2016 HYDRAULIC CLUTCH MARINE GEAR MEMBER AMERICAN GEAR MANUFACTURERS ASSOCIATION MARINE GEARS, INC P.O.
