How Does Mergi Work

Description of the catalytic process

All petroleum based liquid fuels contain a great number of different hydrocarbons. In order to convert these fuels into energy, combustion must take place. Combustion is a chemical process of rapid oxidation. The reaction between the hydrocarbon fuel molecules and oxygen produces heat. The result of complete combustion is water and carbon dioxide. However, incomplete combustion produces carbon monoxide, unburned hydrocarbons, soot and tar.

Small and light hydrocarbon molecules, like those found in gas and naphtha, burn easily. However, the large and heavy hydrocarbon molecules in residual fuel oil are not easily burnt, and require a higher temperature to achieve complete combustion. In combustion, the creation of free radicals affects the speed of combustion. Thermal cracking occurs in molecules when a sufficient temperature is reached. This creates new components that are extremely reactive and immediately seek to combine with oxygen atoms. This oxidation releases heat, leading to further thermal cracking and thus, a chain reaction is created.

Components within Mergi Combustion Improver thermally crack at a considerably lower temperature (approximately 200 degrees Centigrade) than hydrocarbon molecules. Therefore, the concentration of free radicals is increased at an early stage of ignition, which causes an improvement in combustion and a far more intense combustion, once oxidation begins. The result of this process is an increased flame temperature and a more complete combustion of the fuel.

This increase in temperature is an important effect of Mergi Combustion Improver and helps oxidise soot and tar (hydrocarbons with a low hydrogen content) which would have remained to form deposits in the engine, or be expelled with exhaust gasses as pollution. This complete combustion reduces carbon monoxide emissions and increases the heat/energy released from the fuel.

The use of Mergi Combustion Improver increases free radicals ensuring an accelerated and complete combustion.  At the point of ignition, a greater proportion of the fuel in the cylinder is converted to energy. The increased temperature improves the condition of valves and piston rings by burning off soot and carbon deposits, thereby improving compression. The reduced cylinder leakage improves the effectiveness of the engine and further contributes to a reduction in the amount of fuel consumed. Therefore, Mergi Combustion Improver saves fuel in two ways - by increasing the effectiveness of the engine and by causing a more complete combustion of the fuel itself. This produces more energy.

Deterioration Of Marine Fuel Quality

In the 1950's, world refineries processed crude petroleum by atmospheric distillation, producing straight run distillates and residual fuels. With the increased demand for automotive diesel fuel and kerosene, the refinery process improved, meaning a dramatic reduction of straight run residual fuels available to the marine market and the gradual deterioration of marine fuel quality. Modern marine fuels are made from residual fuels rather than straight run distillates and have poor combustion characteristics. The calorific value has remained the same, but the ignition quality has deteriorated significantly.
