22311990 is supplied as a remanufactured replacement injector assembly. Cross-reference numbers: 22311990, BEBJ1F10001. Application recorded for this part: Fits Volvo — 3+3. The injector sits at the end of the rail and does the final metering work: it receives fuel already at high pressure and decides both how much enters the cylinder and how well atomised it is. That combination governs power, smoke and fuel consumption more directly than almost any other part on the engine. What owners usually notice first: longer cranking, a rougher idle, more smoke than the engine used to produce, worse consumption, and occasionally a metallic knock that appears under load and clears once the engine is revved. Because those symptoms also point to compression, turbocharger or air-side problems, it is worth confirming before ordering. A return-flow (back-leakage) test across all injectors and a cylinder cut-out test will usually identify both whether the fault is injector-related and which cylinder is responsible. Installation notes: new copper washers and seals are mandatory, the seat must be clean and undamaged, and the retainers should be torqued to the engine manufacturer's specification. If the ECU stores injector codes for this engine, program them after fitting, otherwise the engine will not compensate correctly. What we do differently: every core is stripped to components, inspected against wear limits and measured before anything is reused. Worn parts are replaced, not cleaned and refitted. After reassembly the unit is bench-tested — delivery, return flow, opening pressure and leakage — and only units inside specification are dispatched. We can send the test sheet for your order before it leaves. Every remanufactured unit carries a 12-month warranty.
