With the introduction of electronics to diesel engines electronic unit injector EUI and electronic unit pump EUP systems were developed. Use Iveco Stralis Eurotracker Eurotech. Quantity variations for injector number 4.

This fuel is pumped into the combustion chamber in precise amounts in order to control engine performance. OEM F 00V X99 996 Iveco ref. However the design of unit pump and unit injector systems is.

Electronic unit injectors are mechanically pressurized using electronic control of governing timing and metering functions. Mechanical fuel injection system has recently been overshadowed by modern electronic injection which enables the use of lambda closed loop control. The small size of the injector along with the trapezoidal valve placement in the cylinder head allows the EUI to be placed in the center of the combustion chamber for optimal fuel efficiency and low emissions.
