METHOD OF SUPPLYING FUEL TO AN INTERNAL COMBUSTION ENGINE

Purpose of work: the purpose of the work is to improve the accuracy of fuel dosing during cyclic supply and reduce toxic emissions of exhaust gases into the atmosphere of an internal combustion engine. The method relates to power and transport engineering and is intended for ground-based power plants and vehicles. The method consists in cyclic fuel supply through the injectors, while measuring the fuel pressure at its inlet during the calibration work of the internal combustion engine electronic control system, by measuring the fuel pressure in front of each injector, the integral value of its drop during the open state of the valve of each injector is determined, depending on crankshaft speed and load on the internal combustion engine and record it in the non-volatile memory of the electronic control unit of the internal combustion engine, and during its operation, before opening the valve of each injector, the fuel pressure at its inlet is increased by the corresponding integral value of its drop during the valve open period injector recorded in the non-volatile memory of the electronic control unit. Due to the correction of the fuel pressure in front of the injector and the correction of the cyclic fuel supply of each individual injector, the accuracy of its dosing is increased, which reduces the toxicity of the exhaust gases of the internal combustion engine.
