(54) РЕГУЛЯТОР ДИЗЕЛЯ С ТУРБОНАДЦУВОМ(54) DIESEL REGULATOR WITH TURBONADZUV

1one

Изобретение относитс к автоматическому регулированию двигателей внутреннего сгорани .This invention relates to the automatic regulation of internal combustion engines.

Известны регул торы дизел с турбонаддувом , содержащие пневматический чувствительный элемент давленн наддува с мембраной, св занной .с одной стороны с впускным трубопроводом дизел , а с другой - с пружиной , и центробежный чувствительный элемент со щтоком, подсоединенным к валу двигател , опирающийс с одной стороны на тарелку, а с другой - на подпружиненную муфту, причем оба элемента св заны с органом дозировани топлива Ц,Turbocharged diesel controllers are known that contain a pneumatic sensitive element of a supercharged pressure with a diaphragm connected to the diesel intake pipe on one side and a spring on the other, and a centrifugal sensitive element with a shaft connected to the engine shaft that is supported on one side on the plate, and on the other, on the spring-loaded sleeve, both of which are connected to the fuel metering authority C,

Однако в известных регул торах, усилие центробежного чувствительного элемента воспринимаетс непосредственно пневматическим чувствительным элементом, что снижает точность регулировани .However, in known regulators, the force of the centrifugal sensing element is perceived directly by the pneumatic sensitive element, which reduces the accuracy of the adjustment.

Цель изобретени - ровышение точности регулировани .The purpose of the invention is to improve the accuracy of regulation.

Дл достижени поставленной цели орган дозировани топлива установлен между пружиной и мембраной и жестко подсоединен к последней.To achieve this goal, the fuel metering authority is installed between the spring and the membrane and is rigidly connected to the latter.

Пружина установлена между центробежным чувствительным элементом и органом дозировани топлива и снабжена с двух сторон упорами.A spring is installed between the centrifugal sensing element and the fuel metering body and is provided with stops on both sides.

На чертеже приведена схема регул тора.The drawing shows a regulator circuit.

Регул тор содержит пневматический чувствительный элемент 1 давлени наддува с мембраной 2, св занной с одной стороны с впускным трубопроводом 3 диэел , а с другой - с пружиной 4, и центробежный чувствительный элемент 5 со штоком, подсоединенным к вращающемус со скоростью w валу 6 двигател . Центробежный чувствительный элемент 5 опираетс с одной стороны на тарелку 7, а с другой - на подпружиненную муфту 8, причем оба элемента 1 и 5 св заны с органом 9 дозировани топлива, установленном между пружиной 4 и мембраной 2 и жестко подсоединенном к последней.The regulator contains a pneumatic sensing element 1 of boost pressure with a membrane 2 connected on one side with the inlet pipe 3 of the dielec, and on the other with a spring 4, and a centrifugal sensitive element 5 with a rod connected to the rotating shaft of the engine 6 at a speed w. The centrifugal sensing element 5 rests on one side on the plate 7, and on the other on the spring-loaded sleeve 8, with both elements 1 and 5 connected to the fuel metering body 9 installed between the spring 4 and the membrane 2 and rigidly connected to the latter.

Цружина 4 установлена между центробежным элементом 5 и органом 9 дозировани топлива и снабжена с двух сторон упорами 10 и П.A spring 4 is installed between the centrifugal element 5 and the fuel metering body 9 and is provided on both sides with stops 10 and P.

Claims

The device works as follows. The change in the engine speed is sensed by the speed sensitive element 5, the movement of which is transmitted through the spring 4 to the fuel metering body 9. The movement of the speed sensor element and the fuel supply determined by the engine speed value are limited by the stop 10. The change in boost pressure perceived by the membrane 2 rigidly connected to the fuel metering body 9 causes the spring 4 to deform, regardless of the engine speed value. An increase in the boost pressure causes the displacement of the fuel metering body 9 to increase the fuel supply. The maximum movement of the fuel metering body 9 is limited by the stop AND irrespective of the position of the speed sensing element. Thus, the fuel supply is determined by the speed mode and the engine boost pressure, and the maximum fuel supply depends on the position of the stop 11. The position of the stop 10 determines the value of the engine speed at the time of the corrector to the constant response. The output of the speed sensitive element to the stop and the termination of its operation does not interfere with the movement of the fuel metering body 9 under the influence of the membrane 2 of the pneumatic sensitive element, up to the output of the fuel metering body 9 to the stop 11. Using a diesel engine with turbocharging will allow the engine to run for 4 regimes that cause a decrease in charge pressure and air supply due to the inertia of the air supply system, carry out the correction of the fuel supply in the entire range of high-speed engine operating conditions. Claim 1. Turbocharged diesel regulator containing pneumatic pressure boosting element with a diaphragm connected on one side to the diesel inlet pipe, and on the other with a spring, and centrifugal element with a rod connected to the engine shaft resting on the one hand, on the plate, and on the other, on the spring-loaded sleeve, both of which are associated with the fuel metering authority, characterized in that, in order to improve the control accuracy, the fuel metering authority is installed ezhdu spring and the membrane and rigidly connected to the latter.

2. The regulator according to claim 1, characterized in that the spring is installed between the centrifugal sensing element and the fuel metering body and is provided with stops on both sides.
