maintenance time and lower maintenance costs.

When Caterpillar goes into pro- duction of its medium-speed 3600 series in 1985, the company will offer four additional models with a continuous output range from 1,700 bhp at 700 rpm to 6,000 bhp at 1,000 rpm.

The 3600 Series engines are ex- pected to be among the most fuel- efficient and durable in their power and speed class—720-1,000 rpm.

Initial rated fuel consumption of 0.327 pounds per horsepower-hour is achieved through system and component efficiency, including turbocharger match, unit injectors, precision injection timing, and high combustion pressure capability.

The family is designed to operate on a range of blended fuels.

COLT INDUSTRIES

Colt Industries' Fairbanks Morse

Engine Division continues to offer both the Colt Pielstick and the

Fairbanks Morse opposed-piston diesel engines. The Fairbanks 38D8-1/8 opposed-piston engine is offered in both blower-scavenged and turbocharged versions, with horsepower ranges from 708 to 3,500 bhp at 750 rpm, and 920 to 4,200 bhp at 900 rpm. These en- gines have always enjoyed high fuel efficiency, but today's sophis- ticated electronic control and mon- itoring systems are squeezing even better fuel economy from them.

Fairbanks Morse continues to produce the Colt Pielstick PC-2.3V and PC-2.5V diesel engines, with ratings from 6,420 to 11,700 bhp at 520 rpm. These engines are ca- pable of burning heavier grades of residual fuels.

The Engine Division now offers the Colt Pielstick PC-2.6 L & V and the high-horsepower PC-4.2V diesel engines. The PC-2.6, with horsepower ratings from 4,422 to 13,266 bhp, is a development of the PC-2 series medium-speed en- gine with the same general dimen- sions. The PC-2.6 engine can burn all heavy fuels available on the market. The engine is fitted with water-cooled cages and exhaust valves, especially adapted to the fuel's vanadium content. The ad- vanced technology of the PC-2.6 engine enables it to burn the poor- est foreseeable heavy fuel without major modifications.

The Colt Pielstick PC-4.2V, rated from 16,270 to 29,286 bhp, is able to burn residual fuels of up to 4,000 sec. Redwood #1 at 100 F with a 400 ppm vanadium content.

The Colt Pielstick engines are backed by SEMT Pielstick's ongo- ing research and development pro- grams. The PC engine family has approximately 60 million hours of experience running on heavy fuels.

CUMMINS ENGINE

Cummins Engine Company manufactures six series of marine diesel engines rated from 170 to

Circle 143 on Reader Service Card ->| 1,250 bhp, continuous-duty opera- tion. Designed for heavy-duty workboat and fishboat applica- tions, both main propulsion and ship service auxiliary power,

Cummins engines have developed a reputation over the years for fuel-efficient power.

Since the mid-1970s, the Cum- mins K marine engines have de- veloped a reputation for fuel effi- ciency as well as reliability. The

KT/KTA-1150 series are in-line, six-cylinder models developing 400- 475 continuous bhp at 1,800 rpm; displacement is 1,150 cubic inches (18.9 liters).

The KT/KTA-2300 and KTA- 3067-M engines, introduced in 1978 and 1980, respectively, complete the Cummins product line with high horsepower, reliability, dura- bility, and fuel economy. The 2300 series engines are a 12-cylinder, V configuration design with a dis- placement of 2,300 cubic inches (27.8 liters). The turbocharged en- gine has a rating of 800 bhp at 1,800 rpm, and the turbo/after- cooled version has a 940 bhp rat- ing at 1,800 rpm.

The KTA-3067-M engine is rated at 1,250 bhp at 1,800 rpm for con- tinuous-duty applications. It is a 16-cylinder engine with 3,067-cu- bic-inch (50.3-liter) displacement.

Recognized at their introduction as the most fuel-efficient marine diesel engines in their horsepower range, the K series engines have been improved continually to re- duce specific fuel consumption.

PROVEN

In a marine engine, dependability is an obvious benefit.

The dependability that keeps an engine running day in and day out, in all conditions, offers safety advantages that are obvious to those who go to sea.

The dependability that keeps a vessel in service, doing its job, run after run, free of downtime, has rewards that are obvi- ous to those who mind the bottom line.

For over 75 years Volvo Penta Marine engines have proven they can deliver that kind of time-tested dependability.

But there's another definition of de- pendability, not so obvious, but vital to the profitable operation of any working craft or fleet of working craft. And that's dependability when it comes to service and support.

It begins with the installation. We put all of our experience at your disposal, from the correct engine specs to pro- peller calculations, from choice of hydraulic equipment and power take-off dimensioning to speed and torque requirements.

VOLVO

When it comes to maintenance we understand that time spent waiting is money lost. That's why we stock a full line of spare parts at convenient locations all around the country, ready to be deliv- ered when you need them. In addition,

Volvo Penta technicians are always on hand to solve particular problems.

A* Volvo Penta we build a complete line of diesel engines for workboats, from 60 h.p. to 400 h.p. Including turbo- charged and aftercooled models that boost power and efficiency potential.

Volvo Penta has made a firm commit- ment to back up its investment in the

North American Marine Industry. A commitment that has built an outstand- ing network of service and support. A system that is your guarantee that we'll be here tomorrow to back up what we sell today.
