In modern diesel engines, control of the quantity and the start of fuel injection performs a complex electronic system, which in addition to these regulations, manage the entire engine operation. This control system has sensors, engine control unit (ECU) and actuators. Engine control unit with integrated microprocessor, analog-digital converter and program memory, converts, analyzes and processes a large amount of computer input data obtained from sensors, and then sends voltage control signal to activate the actuators.
This paper tackles the problem of lack of influence of the sensor signal due to a defect in the overall accuracy of electronically controlled Diesel engines. The aim of this study was to look into the importance of input values of physical quantities, obtained from the sensors, the overall accuracy of eletronically controlled Diesel engines. The study results are based on experimental data obtained by conducting experiments on the four-stroke Diesel engine of Volkswagen Company, power 103 kW, 2 liters volume, with pump-injector fuel injection system, Variable geometry turbocharger, sensors, actuators and EDC16 engine management device connected via CAN data bus in the powertrain. Communication with the engine control unit is performed via OBD socket in a vehicle diagnostic device using VAS 5051B integrated instruments for the measurement technique.
