This is the Delphi EX631084, an E3.5 electronic unit injector remanufactured by Delphi for the 11L Volvo D11 and Mack MP7 at the EPA14 emissions level (the GHG engines). Delphi’s own numbers for it are BEBE4L09001 and BEBE4L15001. It replaces Volvo and Mack numbers 22015763, 22479123, 85013778, 85020031, 85020426, 85020427 and 85144516. It is sold one at a time, and a refundable core applies.

A miss or rough idle that follows one cylinder, hard starting, fuel in the oil, white or black smoke and an injector fault code for one cylinder are the usual reasons these get replaced. Delphi lists a second E3.5 injector for the 11L, EX631078, for the earlier D11 and MP7, with its own list of Volvo numbers. Match the number on your old injector before you order.
