Fuel Technology

Emulsified fuel technology has been developed since the early 1980’s to the improve combustion efficiency of marine diesel engines by creating a secondary atomization effect after the initial fuel injection. The main challenge is to measure the improved sfoc of ships accurately and reliably. This paper presents a proposed method to measure the sfoc accurately and reliably to the order of 1%. Electronic governor also poses new challenge to measuring the sfoc of ships burning emulsified fuel. Meanwhile, fuel types supplied to ship owners are of increased varying properties although still complying to ISO8217 standard. This paper describes the innovations in emulsified fuel technology that were developed to meet these challenges.

It is established, that the destruction of carbon deposits when the engine is running on a water-fuel emulsion occurs due to the phenomenon of micro-impact of emulsified fuel droplets, the evaporation rate of which depends on their diameter, pressure and amplitude of the gaseous medium. As a result of the removal of carbon deposits in the engines, there is an increase in the average compression value for the engine cylinders by 8 % and the engine power by 11 %, as well as a decrease in the specific fuel consumption by 10 % and the smoke of the exhaust gases by 16 %.
