The key design factors of an Hydraulically actuated Electronically controlled Unit Injector (HEUI) which determine its injection rate, pressure, energy efficiency and accuracy of fuel delivery, and the correlations between these design factors and performance parameters, have been established. Two methods of fuel metering within an HEUI are compared in terms of injection accuracy, reliability and controllability. An HEUI design guidelines are outlined.The test results of latest HEUI developed for diesel engines with displacement 1-2.2 litre/cyl. are shown. It provides high injection pressure, rate and accuracy, low energy consumption, unusually wide range of fuel deliveries and readily fits into existing engines.
