NOTE

Ml: Propulsion applications that operate more ttian 3,000 hours per yeor and have load factors over 65 percent.

M2: Propuision appHcations that apemts up to 3,000 hours per yea and have load factors up to 65 percent. Can use Ml engine power up to 16 hours out of each 24 hours of operation; remaining lime, at least 200 rpm below rated engine rpm. Also auxiliary power applications for dediarted hydraulic pump drives, dredge pumps an other constant load appli- cations.

M3: Propulsion applications that operate up to 2,000 hours per year and hove load factors up to 35 percent. Con use full engine power up to four hours out of each 12; remaining time at least 300 rpm below rated engine rpm.

M4: Propulsion applications that operate up fa 800 hours pet year and have lead factors up to 15 percent. Con use full engine power up to one hour out of eadi 12 hours of operation; remaining time at least 400 rpm below rated engine rpm. "Do the right thing, the first time, on time, oil the time ...

It's the Bollinger commitment."

Deere Expands Marine

Engine Line

Deere Power Systems Group introduced Powertech versions of its marine engines at the recent

Fish Expo held in Boston. Deere now offers marinized versions of the 4.5, 6.8 and 12.5 L Powertech units. Deere's Powertech line fea- tures improved application flexibil- ity, including either-side service for twin propulsion applications, flexi- ble auxiliary drives, poly-vee belt drives and a belt guard to accom- modate front driven PTO-adapted units. Performance of the line is tantamount to its success in other applications, and the engine is designed to provide outstanding fuel economy and torque rise, increased power ratings, reduced engine weight and lower smoke levels.

Volvo Penta Extends Diesel

Engine Range

Volvo Penta is looking at 1999 as the year of its product range exten- sion, with an aggressive growth strategy targeting market share of maritime and other markets.

A part of this growth strategy is the agreement between AB Volvo and Deutz AG under which the two companies have agreed on exten- sive cooperation in the develop- ment and manufacturing of diesel engines.

Diesel Analysis Made Easier

The Doctor system from Icon

Research is designed to be simple and accurate, providing the user comprehensive results. The manu- facturer has recently upgraded the system to provide even better per- formance. The Doctor instrument has a completely revised set of electronics which has been designed to allow the user to take engine readings and see calculated realties without having to inter- face to a PC at any stage. The instrument is still able to display the plot of pressure versus angle, but in addition has tabulated results for multiple cylinders
