Feasibility Study of the Fuel Magnetizer in Flex-Fuel Cars

The topic of energy efficiency is currently a subject widely debated in industrial sectors because of its high relevance due to the finite life time of fossil fuels and the need for reduction in consumption and consequently the emissions of gases and the environmental impact. The objective of this work was to evaluate the performance of fuel magnetizers, a product marketed that, according to suppliers, guarantees an improvement in combustion efficiency, representing a saving of 10% to 22% of fuel. For the analysis of the efficiency of the magnetizer, consumption tests were carried out on engine test bench with and without the use of the product in idling speed, 2000 rpm and 2700 rpm. The conclusions obtained showed that the use of magnetizers did not achieve a satisfactory result in the efficiency of internal combustion engines, a possible factor responsible is the high content of ethanol in Brazilian gasoline.
