The primary number identifies this product page. A number shown with different spacing or punctuation can be an alternative writing format rather than a different part. Related injectors may share a similar housing while using different internal calibration, nozzle specification, connector details or application data. Do not assume interchangeability without checking the full original marking.

Application and fitment

This injector is listed for selected JMC 2.8L 4JB1 EU4 S350. Exact fitment can depend on VIN or chassis number, engine code, rated output, build date and regional specification. Before ordering, compare the MPN and OE reference with the removed unit and consult an appropriate serial-number or VIN-based parts catalog.

Use the four-image gallery to compare the electrical connector, high-pressure inlet, return connection, mounting shape, body length and nozzle profile. Physical similarity helps identify the component but does not confirm the internal calibration.

Injector function and performance

A common-rail injector meters high-pressure diesel fuel and delivers controlled injection events into the combustion chamber. Correct operation supports dependable starting, stable idle, balanced cylinder contribution and consistent response under load. Results also depend on clean fuel, correct rail pressure, sound wiring, adequate compression and the condition of the wider fuel system.

Common signs an injector may need attention

• Hard starting or extended cranking
• Rough idle or uneven cylinder contribution
• Reduced power under acceleration or load
• Increased exhaust smoke
• Abnormal combustion noise
• Excessive injector return flow
• Injector-related diagnostic fault codes

These symptoms do not prove injector failure. Contaminated diesel, low rail pressure, restricted filters, wiring faults and mechanical engine problems can cause similar complaints. Professional diagnosis and suitable injector testing are recommended before replacement.

Installation and coding

Installation should be completed by a qualified diesel technician using clean working practices. Protect high-pressure connections from contamination, inspect related pipework and renew required seals. Follow the service procedure for the exact application. If the control system uses injector correction or compensation data, check and register it with suitable diagnostic equipment.
