INCREASING THE SPEED OF THE PRESSURE REGULATOR IN THE FUEL INJECTION WITH THE PURPOSE OF REDUCING PULSATIONS IN THE FUEL SYSTEM AND OPTIMIZING THE WORKING PROCESS IN THE DIESEL
Abstract
The article discusses the possibility of increasing the speed of the pressure regulator in the high-pressure fuel pump of the Common Rail system in order to reduce the pressure pulsation. A more stable pressure in the fuel accumulator allows achieving accurate and uniform cyclic feed through the cylinders, which in turn is necessary to achieve high environmental and economic indicators. The influence of the pressure regulator speed on the pressure fluctuation range in the fuel accumulator is estimated. It is shown that with an increase in the operating speed of the injection pump, the efficiency of maintaining a stable pressure decreases. Actions have been developed to improve the efficiency of the pressure regulator in regulation and positive tests have been obtained in practical tests of a complete fuel system.
