Volvo 20747797 Electronic Unit Injector Assembly

The 20747797 is a Delphi E3 Electronic Unit Injector (EUI) designed for Volvo heavy-duty diesel engines including MD11, MD13, D11, D13, and D9B series. It integrates the injection nozzle, high-pressure pumping element, and solenoid actuator into a single unit mounted directly on the cylinder head. The injector operates under high pressure to deliver precise fuel metering and atomization for Euro 4 and US07 emission compliance. Constructed with high-speed steel internal components and hardened nozzle needles to withstand extreme cylinder pressures and thermal cycling. The solenoid valve assembly is calibrated for fast response time and minimal leakage. This assembly replaces Volvo OE numbers 20582430, 21582101, 21644602, 85000674, 85003951, 85006674, and 85009951.
