This book covers the following Sulzer diesel engines: The Sulzer RTA84C engine with the following MCR rating: – Power per cylinder 050 kW – Speed 102 rpm 510 bhp and The Sulzer RTA96C engine with the following MCR rating: – Power per cylinder 490 kW – Speed 100 rpm 470 bhp This issue of the Engine Selection and Project Manual (ESPM) replaces the ESPM RTA84C issue May 1997 and ESPM RTA96C issue May 1997 It is made according to the new concept for these books Please note that the contents have been revised, which will have consequences on new projects and could have an influence to your actual projects Particular attention is drawn to the major changes: a) b) c) d) e) Both engines are fully compatible to IMO-2000 regulations The estimation of engine performance data (BSFC, BSEF and tEaT) are given only for MCR rating Derating and part load performance figures can be obtained from the winGTD-program (CD-ROM included inside the rear cover of this book) Complete document (text, data, schematics and outline figures) has been updated The inclusion of information referring to IMO-2000 regulations The inclusion of information referring to winGTD (version 1.22, mentioned under b) and EnSel (version 3.22), both on the CD-ROM included inside the rear cover of this book 25.41.07.40 – Issue VII.98 – Rev Wärtsilä NSD Switzerland Ltd RTAĆC Engine Selection and Project Manual List of
