(continued from page 29) (DOT) combustion analysis system designed and manufactured by

Megasystems, Inc. of Boca Raton,

Fla., is a diagnostic tool for use on diesel ships. This system provides the operator with a simple and straightforward method of accurate- ly tuning diesel engines to their optimum performance. No operator set-ups or calibrations are required.

The DOT system measures more than one cylinder at a time, thereby to give \

Use of the DOT system provides two major benefits. First, it allows operators to observe the time of ignition, expansion time, peak pres- sures, etc., in direct relation to the crankshaft position, decreasing fuel costs significantly. (For each 1° the crankshaft angle is off, a 2-percent fuel loss occurs.) Second, it allows operators to balance cylinder power output, reducing heat imbalance, vi- bration of the engine, and increasing the engine's life.

The standard DOT system con- tains a small CRT, a processing unit, and two sensors that are at- tached to the engine. Information from the sensors is displayed as a waveform, which is analyzed by the operator.

MITSUBISHI KK

Mitsubishi Kakoki Kaisha, Ltd. of Japan is offering literature on three new products that the compa- ny recently placed on the market as a solution to the fuel quality prob- lem. The products are the Selfjector

Excellent-Series (SJ-E), the e-HID-

ENS-System, and the Marine De- canter Centrifuge.

The attractive 16-page brochure on the SJ-E explains that the new unit is a remodel of the original Self- jector (disc type centrifugal separa- tor) that incorporates many new features such as a pilot valve mecha- nism in a high-tensile stainless-steel bowl, and the introduction of a mi- croprocessor into the automatic control system.

Seven models of total and partial discharge separators are available so that the most economical unit for any particular main engine can be selected. The brochure contains cut- away color views, text, and impor- tant data on the various models and the automatic control system, as well as dimensions and space for installation.

The six-page brochure on the e-

HIDENS-System states that the de- terioration of fuel oil for diesel en- gines prompted the development of this high density fuel oil treatment system. The pamphlet contains an outline of what the system is, and discusses its features, actions, main components, and throughput capac- ity. Several pages of drawings, charts, and diagrams complement the text.

The Mitsubishi Marine Decanter

Centrifuge is the subject of litera- ture that points out it was also developed to cope with the deterio- ration of marine fuel oils, and that it fully meets the requirements for the clarification of low grade fuel oils with high viscosity, high specific gravity, and especially high content of sludges. The brochure covers the principles and and structure of the

Decanter Centrifuge, its features, the effect of two-stage purification through the combination of Marine

Decanter KVZ-M and Disc Type Oil

Purifier (MHI Selfjector), and spec- ifications for the various models.

NORCONTROL

The DCS 8800 digital governing system from Norcontrol of Norway provides a complete package solu- tion for all speed-governing tasks on low-speed, long-stroke engines. Us- ing compressed air as a power me- dium, its main purpose is to regulate the position of the engine fuel servo in order to keep engine speed equal to a reference speed setting. The lat- ter can be set from two selectable ship systems, usually the bridge or engine room, while slowdown or shutdown signals from external safety systems trigger an automatic response.

Two separate and self-contained computer processing sub-systems are combined in the package—han- dling speed regulation and fuel ac- tuation functions, respectively.

These sub-systems employ similar hardware modules, in line with Nor- control's general commitment to highly standardized equipment and
