Waste heat fuel-saving device of diesel internal combustion engine

Abstract

The invention discloses a waste heat fuel-saving device of a diesel internal combustion engine. In order to solve the technical problem that waste heat energy exhausted by an air cylinder of the internal combustion engine after operation is utilized to heat diesel before the diesel enters the air cylinder, and the diesel is magnetized after being heated. The device comprises a control circuit, a heat supply device for heating the diesel and a permanent magnetic assembly; the heat supply device is an enclosed hollow cylinder which is internally provided with a diesel delivery pipeline axially; the inlet end of the delivery pipeline is communicated with the output end of a fuel spray pump of the internal combustion engine, and the outlet end of the delivery pipeline is connected to the input end of an air cylinder spray nozzle of the internal combustion engine through the permanent magnetic assembly; and the heat supply device is also provided with a waste heat air inlet and a waste heat air outlet. According to the invention, the viscosity of the diesel entering the air cylinder of the internal combustion engine is controlled within the range of 6.5-7.5mm<2> / s; under the magnetization of greater magnetic field intensity, and the diesel molecular group becomes fine, thus the diesel entering the air cylinder of the internal combustion engine can be burned fully, fuel oil is saved, the emission of black smoke is restrained, thus being environmentally-friendly.

Therefore, saving energy and reducing pollution is a major task for diesel engine manufacturers. For this reason, relevant state departments and many companies have invested a lot of money to concentrate manpower and material resources on research and development of new products that reduce consumption and save fuel. At present, similar to high-efficiency Fuel-saving devices such as magnetized fuel economizers and fuel grinders have emerged as the times require, but their effects have not been significantly improved: 1) In order to reduce the viscosity of diesel oil and improve its atomization quality, some improved devices use electric heating components to heat diesel oil, which consumes electric energy , and not very safe; 2) In order to refine diesel molecular clusters, some improved devices use permanent magnets to magnetize diesel fuel, but the position of the magnet assembly used is unreasonable, some directly place the magnet in the oil passage, and some magnetize first After heating or magnetization while heating, the result is still insufficient combustion, black smoke, and difficulty in starting
