| description | Introduction. Operational methods to monitor the power indicators of engines for continuous diagnosis of their technical condition are of particular interest for creating optimal operating conditions of motor and tractor machinery. The methods are characterized by the mechanical efficiency, determined in the conditions of repair shops with the use of complex braking devices.
Aim of the Article. To present the results of research on the development of an operational method for determining the mechanical efficiency of diesel engines with batteryoperated electronically controlled fuel supply systems.
Materials and Methods. The Bashkir State Agrarian University proposed and successfully tested an operational method for assessing the technical condition of diesel engines with direct-acting fuel equipment on their mechanical efficiency, which is determined by the performance of their fuel equipment adjusted using the diesel itself as an adjusting stand. The possibility of using the proposed method for diesel engines with storage fuel systems was investigated.
Results. The accuracy of determining the mechanical efficiency of diesel engines by electronically controlled fuel systems of battery type can be affected by the features of their work – the correction of cyclic feeds by the electronic engine control unit depending on the technical condition of the cylinders and high fuel injection pressure. To test this hypothesis, there were carried out studies on a four-cylinder D4EA 2.0 engine of a Hyundai Tuscon car with a Common Rail type storage fuel system. The engine fuel supply system was supplemented with an electronic unit integrated between the injector and the standard engine control unit, which interrupted the transmission line of the control signal to the injector according to a given algorithm without the standard unit transition to emergency mode. It has been found that the proposed method can successfully determine the technical condition of the engine as a whole and of its individual cylinders (alternating disabled and working cylinders).
Discussion and Conclusion. The proposed operational method for determining the mechanical efficiency can be successfully used for diesel engines with accumulator electronically controlled fuel supply systems. At the same time, an increase in the cyclic supply by the electronic control unit of the engine fuel supply system reduces the mechanical efficiency slightly, and it can be taken into account only in special cases. |
