Abstract
The article considers the influence of the fuel magnetic treatment onto the operation of a ship engine. Many shipowners are interested in reducing their fuel consumption. Fuel efficiency is one of the most important indicators of a ship's engine. There are various methods to improve the fuel quality. In addition to traditional physical and chemical methods, wave effects are also used, for example, a magnetic treatment. The magnetic treatment effectiveness for diesel fuels has been confirmed by many studies. The analysis of the influence of the magnetic treatment of diesel fuel with a magnetic induction of 0.4 T on the operation of a 4CHN9.5/11 marine engine under different modes is carried out. Magnetic treatment of the fuel was carried out by creating a magnetic field with permanent magnets NdFeb (neodymium - iron - boron) installed in special magnetizers on the fuel line to the high-pressure fuel pump.The methods of analysis of changes in external indicators of the 4CHN9.5/11 engine during magnetic treatment of fuel are considered. The pictures of the 4CHN9.5/11 engine tested are presented. The results of the parameters of the 4CHN9.5/11 diesel engine (effective power, speed, average effective pressure, hourly fuel consumption, specific effective fuel consumption) during tests on load and screw characteristics before or after installation of the magnetizer are presented. The bench tests have confirmed that the reduction in fuel consumption when testing a diesel engine running on magnetically treated fuel makes 5-8%. It is noted that with other types of marine fuel and on other models of engines it is possible to clarify the methods of using magnetic processing in sea and river transport
