System of diethyl ether injection in diesel injection suction drawer 1NVD-24
The paper presents a solution to the problem associated with a high content of harmful substances in the exhaust gases of a diesel engine. The classification of possible solutions to reduce the toxicity of exhaust gases of a diesel engine is given. A system for supplying dimethyl ether to the diesel intake manifold has been proposed, and its work has been considered. Details described the work on the creation of an electronic control unit and an application for controlling the experimental setup, as well as the element base and the cycle of the program code. The scheme of interaction of the microcontroller with the main components of the installation is shown. The results of experiments on the supply of dimethyl ether to the diesel intake manifold are given. The obtained experimental data indicate that when dimethyl ether is added to the air mixture, the specific consumption of diesel fuel decreases to 13.1%, depending on the mode of supply of dimethyl ether. The concentration of nitric oxide NO is reduced to 35%. The concentration of nitrogen dioxide NO<sub>2</sub> increases to 100% (from 63.9 to 135.3 ppm). The concentration of NO<sub>x</sub> is reduced by 6%. The concentration of carbon monoxide CO increased up to 6 times.
