PROPULSION GUIDE same size (see Figure 3). The 200- kg unit can then be removed from the engine, and readily replaced by an overhauled unit. According to MAN B&W, this concept has resulted in a signifi- cant reduction in working hours on maintenance/overhaul compared with other engine procedures, with the simple cylinder unit approach offering cost savings in the long run.

The mechanical diesel engine indicator — a spring- loaded device for recording peak cylinder pressure and compression curves — emerged out of his field of work. Lehmann & Michels have built mechanical diesel indicators since 1911, and their recently introduced Premet line of electron- ic engine indicators brings the technology into the 21st century. The Premet line of handheld electronic indicators consists of electronic and pressure sensing elements in a compact, stainless steel housing. Data acquisition is reportedly quick and accurate, and A.D.S. Announces Fall Certification Exams The Association of Diesel Specialists (A.D.S.) has scheduled the fall TechCert examinations for its program of voluntary certifica- tion for diesel technicians. The exams are reportedly offered at more than 600 locations through- out the U.S. and at 11 test centers in Canada. Exams to held on November 6 and 13 include: Diesel Engine Theory & Operation; Distributor Fuel Injection; Inline Fuel Injection; Turbochargers/Blowers; and Injectors/Unit Injectors. A mini- mum of one year's experience or completion of a technical school diesel course is required for test registration. For more informa- tion, contact A.D.S. at tel: (816) 444-3500.
