Abstract

Изобретение обеспечивает повышение точности регулировани  угла опережени  впрыска топлива в дизель путем изменени  зазора между кулачковым валом топливного насоса высокого давлени  и исполнительным механизмом в муфте угла опережени  впрыска топлива. Дл  учета динамического показател  топливоподачи измен ют ос га- точное давление (Д) в трубопроводе высоко го Д между топливным насосом высокого Д и форсункой. Сравнивают измеренную величину Д с остаточным Д, измеренным пои минимальном удельном расходе топлива дл  данного двигател  внутреннего сгорани . В соответствии с результатами сравнени  измен ют зазор между кулачховы валом 1 топливного насоса высокого Д и исполнительным механизмом муфты, приРизм чем при гоотношении - 1 увеличивают зазор до достижени  Ризм - Рост., а при соотношении 1 уменьшают его д-з ост достижени  РИЗМ Р ос, . 2 илThe invention improves the accuracy of adjusting the fuel injection advance angle to diesel by changing the gap between the camshaft of the high pressure fuel pump and the actuator in the coupling of the fuel injection advance angle. To take into account the dynamic fuel delivery rate, the axial pressure (D) in the high D pipeline between the high D fuel pump and the nozzle is changed. Compare the measured value of D with the residual D measured by the minimum specific fuel consumption for a given internal combustion engine. In accordance with the results of the comparison, the gap between the cam shaft 1 of the high-D fuel pump and the clutch actuator is changed, and with a ratio of 1, the clearance increases the gap until it reaches Rism-Growth, and, at a ratio of 1, decreases its distance to reach RISM P , 2 yl

Формула изобретенияClaim Способ регулирования угла опережения впрыска топлива в системе питания дизеля, заключающийся в том, что измеряют частоту вращения вала дизеля и параметр, характеризующий подачу топлива, и в зависимости от результатов измерения изменяют угол опережения впрыска топлива, отличающийся тем. что, с целью повышения точности регулирования, в качестве параметра, характеризующего подачу топлива, измеряют остаточное давление в трубопроводе высокого давления системы питания дизеля, сравнивают величину измеренного остаточного давления с заранее заданной величиной давления, причем если измеренная величина остаточного давления превышает заданную величину, то угол опережения впрыска топлива уменьшают, а если измеренное остаточное давление меньше заданного, то угол опережения впрыска топлива увеличивают.A method of controlling the angle of advance of fuel injection in the diesel power supply system, which consists in measuring the frequency of rotation of the diesel shaft and a parameter characterizing the fuel supply, and depending on the measurement results, change the angle of advance of fuel injection, characterized in that. that, in order to improve the accuracy of regulation, as a parameter characterizing the fuel supply, measure the residual pressure in the high pressure pipe of the diesel power system, compare the value of the measured residual pressure with a predetermined pressure value, and if the measured value of the residual pressure exceeds a predetermined value, then the angle the fuel injection lead is reduced, and if the measured residual pressure is less than the predetermined one, the fuel injection lead angle is increased. л l л, l А/ A/ X X /V / V Л) L) ь / - b / - £ о ч £ o h
