5.5 Other Injector Component Parts
(1) Hollow Screw with Damper
• The hollow screw with damper enhances injection quantity accuracy, by reducing the back-pressure pulsations (pres-
sure fluctuations) of the leak fuel. In addition, it minimizes the back-pressure dependence (the effect of the pressure
in the leak pipe changing the injection quantity even though the injection command is the same) of the fuel in the leak
pipe.
(2) Connector with Correction Resistor
• The connector with correction resistor has a built-in correction resistor in the connector section to minimize injection
quantity variation among the cylinders.
