AMERGIZE - Deposit Modifier/Combustion Improver
Description
AMERGIZE deposit modifier/combustion improver is a unique blend of oil soluble organometallics which have been shown to be most effective in 2-stroke and 4-stroke diesel engines operating on heavy fuel oils. Engine tests have shown that the combined ingredients in AMERGIZE deposit modifier/combustion improver provide a synergistic effect to reduce deposits and improve combustion.
The combustion improver in AMERGIZE deposit modifier is effective for both medium- and slow-speed diesel engines experiencing problems related to combustion and deposits resulting from vanadium, sulfur and sodium contaminants in the fuel.
The deposit modifiers in AMERGIZE deposit modifier work during the combustion process by reacting with these contaminants (vanadium, sulfur and sodium) and changing the composition of the ash. They prevent high- and lowtemperature corrosion more specifically: (1) by raising the melting point of the vanadium compounds so they are nonadherent and noncorrosive to high-temperature surfaces, (2) by changing the crystalline form of the ash so that it is light, friable and easily exhausted, (3) by inhibiting the vanadium so that it cannot act as a catalyst to convert SO2 to SO3 and (4) in its capacity as an alkaline compound, by neutralizing any acid formed.
Joint tests conducted with a major engine manufacturer proved that AMERGIZE deposit modifier/combustion improver can substantially prevent the buildup of deposits on the gas side of turbochargers. As a result, with the use of AMERGIZE combustion improver, the rated efficiency of the turbocharger can be maintained and waterwashing can be significantly reduced. The combustion improver in the product contains an effective catalyst which lowers the ignition energy required to more effectively complete the combustion process, thus providing less carbon deposits, soot and smoking. In addition, laboratory tests with test bed engines have shown that AMERGIZE combustion improver will reduce specific fuel consumption.

Application and Use
The typical dosage rate for AMERGIZE deposit modifier/ combustion improver is in the range of 1 liter to 1,000-8,000 liters (1-8 tons) of fuel. Rates will vary depending on the contaminant levels of the fuel, engine design and operating conditions of the vessel. Drew Marine's alliance with ABS Oil Test provides professional fuel analysis to monitor the hysical and chemical characteristics of the fuel. This service will optimize the benefits of using AMERGIZE deposit modifier and is available in all major ports worldwide via courier service to eight (8) strategically located laboratories. Consult your local Drew Marine service representative for a recommendation based on your vessel’s needs or for additional information. Listed below is a “Rule of Thumb” guide for recommending the proper dosage rates. Since these contaminants exist in combination, the dosage rate selected should be the one corresponding to the highest level of the major contaminant present.

It is recommended that the product be fed continuously into the fuel. This is best accomplished by the use of a metering pump. Dosing in this manner assures proper mixing, dispersion, and sufficient quantities of AMERGIZE® deposit modifier/combustion improver when needed. It is usually recommended that the product be dosed to the low-pressure side of the fuel treatment system, but the actual dosing location may vary depending on the engine layout and design. The diagram below outlines typical treatment locations.
