Sulzer forms JV in China

Abstract

Two medium-speed engine series are fielded by the Anglo Belgian Corporation (ABC) for propulsion and auxiliary power applications. The 242 mm bore/320 mm stroke DX type is produced in three, six and eight in-line cylinder versions to cover an output band up to 883 kW at 720 or 750 rev/min. DX models are naturally aspirated; DXS models are turbocharged; and DXC models are turbocharged and intercooled. A Japanese contender in the domestic and international small-bore medium-speed engine arenas, Daihatsu evolved its current program from the PS series which was developed in 1950 and helped establish the company as a major supplier of auxiliary diesel engines. Some 10 000 examples of the PS-26 model, for example, were sold worldwide. A wide range of medium-speed engines were designed and produced over many years by Grandi Motori Trieste (GMT), the A55 series, was the final evolution of a 550 mm bore model first designed and produced in Torino. Hyundai Heavy Industries developed its first own-design medium-speed engine, the 210 mm bore HiMSEN H21/32 series, for launching in 2001. Mirrlees Blackstone's final program—now phased out—was headed by the 800 kW/cylinder MB430L engine, a 430 mm bore/560 mm stroke in-line cylinder derivative of the MB430 design which was launched in V45° cylinder form in 1985 with a shorter stroke of 480 mm. A major licensee of MAN Diesel in the production of MC/ME low-speed engines, Mitsui also once offered its own 420 mm bore/450 mm stroke medium-speed design whose last version was designated the L/V42MA series. A wide range of own-design high- and medium-speed engines from Niigata Engineering of Japan was supplemented by licences to build SEMT-Pielstick PA and PC series and MAN B&W Holeby 23/30 and 28/32 series engines. The medium-speed engine market has long been dominated by four-stroke, uniflow-scavenged designs but at one time a number of two-stroke designs enjoyed popularity, notably the Polar loop-scavenged type—which ceased production when Nohab introduced its four-stroke F20 range—and Sulzer's uniflow-scavenged ZH40.
