In 1989, as part of MTU's con- tinuous development program, the

TE version of the 396 engine was introduced and was readily accepted by customers. The TE suffix de- notes engines with split engine and charge-air cooling circuits with plate-type heat exchanger, in which charge-air temperature is controlled in close accordance with engine load.

Series 396 TE engines in twin-hull ferryboats have logged up to 11,000 operating hours without any notable malfunctions, according to the manufacturer. In 1992, MTU passed a significant milestone with the sale of the 10,000th engine from the 396 series. In the 396 series, MTU

Friedrichshafen has a technologi- cally mature product with a unique breadth of application, a product which will continue, in the coming years, to enjoy outstanding sales opportunities on the world market.

New Sulzer Diesel

New Sulzer Diesel Ltd. in

Winterthur, Switzerland, has a fam- ily of three basic engine types: the

RTA series of low-speed two-stroke diesel engines, the ZA40S medium- speed four-stroke diesel engines and the S20 high-speed four-stroke en- gines. At the top of the power range, the Sulzer RTA84C engine has be- come the market leader in the pro- pulsion of large, fast containerships, with 59 engines delivered or on or- der. The first 12-cylinder engine of this type, giving 45,840 kW (62,400 bhp) output, completed testing in

July. Three further 12-cylinder en- gines were recently ordered for 4,800 teu containerships contracted in Ja- pan. The longest-running RTA84C engines have 17,000 hours opera- tion and they have earned an excel- lent reputation. They are already giving two-years service between overhauls.

The first example of the RTA84T engine is currently undergoing testbed trials at the Aioi works of

Diesel United Ltd. in Japan. Spe- cifically designed for VLCCs, the

RTA84T offers much lower propel- ler speeds. In the RTA84T, part- load fuel economy has been consid- erably improved by incorporating flexible engine setting with variable injection timing, variable exhaust closing and load-dependent cylin- der cooling. In the medium-power range, the Sulzer RTA52U, RTA62U and RTA72U upgraded engine de- signs, which were announced last year, are coming into production at various licensees.

The Sulzer ZA40S has established considerable market success in the cruise ship, ferry and Ro/Ro vessel markets. Early this year, three sepa- rate cruise ships were ordered in

Italy and Finland, together having 16 engines totalling 142,560 kW (194,040 bhp): for Carnival Cruise

Lines, P&O Cruises and NYK Line.

These will all be diesel-electric "power station" installations to meet the vessels' complete energy require- ments for propulsion, maneuvering and electrical services. The diesel generating sets will be resiliently mounted for the maximum comfort of passengers and crew.

The Sulzer S20 is primarily being applied in marine generating sets with a power range of420-1,400 kW (570-1,960 bhp). It is specifically designed for reliable operation on heavy fuel oil so that it can be em- ployed in uni-fuel installations burn- ing the same fuel as the much larger main engines.
