Dual Mode Fluid Controlled

Injector System From AMPS

Saves Maintenance, Fuel Costs

Automated Marine Propulsion

Systems, Inc. (AMPS) offers Dual

Mode Fluid Controlled Injection

Systems (FCIS) which have been operating for over 200,000 combined hours on more than 50 slow- and medium-speed diesel engines world- wide. The FCIS can operate on heavy fuels or conventional diesels.

According to AMPS, Inc., the FCIS saves from 3 to 7 percent in fuel and decreases maintenance and spare parts costs. The FCIS fuel injectors operate 25,000-35,000 hours. AMPS guarantees its injectors will operate on the fluid controlled injection mode for two years or 12,000 hours and on any fuel without removing the injec- tors for overhauls.

Fuel injector failures cause sei- zures in pistons and piston crown cracks. The atomization pattern from improperly designed and func- tioning mechanical fuel injectors creates thermal stress on the cylin- der cover flame deck and liner wall.

This causes "cold corrosion" and ther- mal stress cracks which result in excessive wear and premature fail- ure of these major engine compo- nents. Malfunction of fuel injectors

Schematic drawing of AMP's Fluid Controlled Fuel Injector. injectors have constant flow features to prevent solidification of the heavy fuel into fuel lines and related ele- ments of the fuel system. This al- lows marine engines to operate with heavy fuel, cool fuel valves and pre- vents corrosion usually caused by cooling water.

The fluid surface tension effect centers the needle valve, acts as force lubrication and prevents pen- etration of heavy contaminated fuel between needle and valve guideway.

FCIS fuel injectors have very few mechanical internal parts, prevent- ing impact wear of the precision parts of the fuel injector atomizer and significantly increasing operat- ing life of the injector valves. FCIS offers precise needle valve lifting and opening times, resulting in bet- ter combustion.

An important reliability feature of the FCIS is, in event of a decrease in fluid control pressure of the pri- mary fluid control line, an indepen- dent secondary mode of operation takes effect automatically, as a backup system. If the individual fuel injector loses control pressure then the fuel pump and injector are automatically switched off from the fluid control line but the engine con- tinues to operate without interrup- tion.

The AMPS fuel injector is simple and reliable, according to the com- pany. It has two separate indepen- dent modes of operation. The FCIS
