Electronic Unit Injectors
The Electronic Unit Injector was designed to meet the need for higher injection pressures from that of the conventional injection system due to government legislation decreasing the amount of diesel particulates being pumped into the
atmosphere. The Electronic Unit Injector (EUI) comes into direct contact with the cylinder head, where fuel is supplied from internal ducts in the head itself. Each injector has its own pumping element and fuel solenoid valve. Low pressure
fuel is fed to the cylinder head and into each injector fuel port. The pumping action of the EUI is controlled directly by the engines camshaft. The electronic control unit (ECU) allows for temperature compensated injection timing and even cylinder balancing.
Electronic Unit injector fuel systems include; Caterpillar 3406E, Cummins N14, Detroit Series 60, Volkswagen, and Volvo.
