(Continued from page 25) 3,500 bhp at 1,950 rpm for high speed marine applications. With an overall length of approxi- mately 9' by 6' by 4', and at just under seven tons, the full marine specification engine can truly be classed as a compact unit making it ideal for high speed ferry, larger luxury yacht or for on board power generation applications. Designed to complement the Paxman Valenta and Vega engine range, which are well known in the military markets, the VP185 is ex- pected to feature prominently in the commercial markets during the next few years. Paxman expertise, coupled with unparalleled customer support, full training and overhaul facilities, and supported by a worldwide network of representatives and distributors, enables Paxman to offer customers complete application packages.

This new six cylinder engine will be marketed along with the highly successful 6-4V-9 six cylinder diesel which produces 600 hp in produc- tion form. This new 10.3 liter engine will be offered in standard form with a power output of 720 hp. In terms of size, the new engine can be fitted as a direct replacement of the existing 600 hp engine which will remain in production. The 600 hp 6-4V-9 and the 720 hp 6-4V-10 are raw-water cooled, inline six, wastegate turbocharged, four- stroke diesels. Unlike any other marine diesel, the SeaTek family has dual overhead cams, four valves per cylinder and a unique "Swans Neck" intake manifold that promotes low end torque and improved low end combustion. The water-cooled turbocharger and wastegate ensure a smooth, even transition from idle through full boost at 3,150 rpm. If plans call for the building a 38- foot to 58-foot pleasure or patrol boat, SeaTek marine diesel engines will provide the performance edge with only half the weight of com- parative diesels. SeaTek's diesel marine engines are precision built strictly for marine use, with proven reliability and longevity in offshore racing.

Pielstick engines starts from the PA4 high- speed engines with a power of 740 kW (1,000 hp) at 1,500 rpm, and reaches 23,400 kW (31,825 hp) per unit with the medium-speed PC type at 430 rpm. S.E.M.T. Pielstick have much experience with its diesel en- gines in service on merchant and navy ships, as well as in non-mari- time applications. S.E.M.T. Pielstick facilities are located in three sites in France, and the company's engines are manufactured by 25 licensees in the world. Some recent develop- ments with the company's engines include: The PC4-2 B engine has an output of 1,300 kW per cylinder at 430 rpm, a 570 mm bore and 660 mm stroke and is available in variations from 10 to 18 cylinders. Six 18- cylinder engines of this type were recently put into service in an In- dian powerplant, and four more en- gines have recently been ordered from other buyers. The PC2-6B en- gine has an output of 630 kW per cylinder at 530 rpm, a 400 mm bore and a 500 mm stroke, and is avail- able in variations from six to 18 cylinders. A recent innovation for this type of engine is the possibility of using a cast-iron frame machin- ing in S.E.M.T. Pielstick's Saint- Nazaire facility of an 18-cylinder engine, which is part of an order for three engines. Also, a sequential turbocharging which consists of su- percharging the engine with only one turbocharger for loads up to 50 percent of the nominal power, and to put in service the second identical Maritime Reporter/Engineering News MAN B&W proudly announces its 100th consecutive year of constantly increasing Diesel efficiency The outstanding event in MAN's long tradition was the development of the Diesel engine in Augsburg < world's first 100 years ago. This pioneering achievement still retains its guiding impetus, and not only for us. Thorough comparison with all other energy systems has proven its trend-setting role in the development of economically ^ff propulsion optimised and power generation technology throughout the world.
