Abstract

Information about the parameters of the fuel supply is necessary to assess the operational and environmental performance and condition of the diesel engine of the car and tractor. To obtain such information, a special sensor is required, which is highly sensitive and is not built into the power system. The paper provides an analytical description of the processes in the overhead electromagnetic diesel fuel injection sensor. According to the selected electromagnetic circuit, an equivalent circuit is presented. Reasonable assumptions are made for the converter under consideration. Analytical dependences of electrical and magnetic parameters of a non-linear sensor circuit are presented. The conditions for obtaining the maximum sensitivity of the sensor are determined. An algorithm for calculating the magnetic circuit is presented. For the selected design parameters and operating current, the optimal frequency and supply voltage were determined.
