0445120265 Common Rail Injector by the Numbers
Verified identity and fitment data for the complete diesel common rail injector, supplied for the Weichai WP12 and WP10 heavy-duty range.
Each 0445120265 is a common rail injector and a solenoid injector in the CRIN2 family; the diesel common rail injector class serves Weichai WP12 and WP10 heavy-duty trucks. The bosch common rail injector reference 0 445 120 265 is shown for interchange only. This 0445120265 diesel injector carries the Bosch 0 445 120 265 reference on the body, so a bosch 0445120265 injector search resolves to the same WP12 and WP10 fitment, and the 0445120265 fuel injector listing covers the whole WP12 / WP10 family.
Vehicle Compatibility for 0445120265
This complete injector runs the Weichai WP12 and WP10 heavy-duty diesel engines in Chinese heavy trucks and construction machines. Match the engine nameplate and the number on the old injector before ordering.

Most buyers arrive with a 0445120265 injector number alone, so the whole WP12 and WP10 family sits on this page. A weichai wp12 injector on a HOWO A7 or a DeLong tractor is the same assembly as the unit fitted to a Foton Auman GTL — and that same part number also covers the weichai wp10 injector used across the WP10 fleet. The unit also answers the howo injector, shaanxi delong injector and jac truck injector requests, and the heavy duty truck injector buyer who needs a 12l diesel injector replacement for a 612630090001 build. Industrial and marine derivatives of the WP12 and WP10 use the same unit, including gensets and construction machinery on the WP12 / WP10 platform.
Fitment verification
- VIN or chassis number — we decode the build record to confirm the engine family.
- Engine code plate — the plate on the block must read Weichai WP12 or WP10, not another family.
- Photo of the old unit — the number stamped on the injector body, so we match the code and not just the engine.
About the 0445120265 Injector
What the complete CRIN2 unit is, and how it sits in the Weichai fuel system.
What is a common rail injector?
This is the solenoid unit that meters and atomises fuel from the rail into the combustion bowl. The 0445120265 is a complete unit in the Bosch CRIN2 family: the whole injector, not just a spray tip.
How does a common rail injector work?
The rail holds fuel at pressure and the ECU fires the solenoid, so the needle lifts for a controlled window. On a Weichai WP12 or WP10 engine the valve opens, the spray forms, and the ECU trims each cylinder individually. A worn 0445120265 diesel injector shows up as a weak cone or a seeping seat long before it stops running.
Complete unit versus parts
The injector is the complete assembly; diesel injector parts and fuel injector parts such as the valve and seat sit inside it. The common rail injection system meters fuel through a diesel fuel injector on each cylinder, and a bosch diesel injector reference (0 445 120 265) is a CRIN2 unit — the whole assembly, not bare common rail injector parts. A common rail diesel injector of this generation leaves the factory as one sealed unit, and we supply it that way.

As a bosch injector built to the Bosch 0 445 120 265 specification, this 0445120265 fuel injector is a complete common rail unit. The common rail injector specifications list the CRIN2 family, the CRIN2-16 class rating of 1600 bar, and the 12-month warranty. We bench-check injector flow rate and injector spray pattern; the interchange references 0445120086 and 0986AD1016 are shown as Reference. Net weight, flow rate, coil resistance, per-unit opening pressure and the injector correction code are left as Not published because sources conflict or the manufacturer does not release them, so only the packaged shipping weight of 2.5 kg is stated. Pressure is a CRIN2-16 class rating, not a per-unit calibration, so we state only what we can verify for this fuel injector. Injector identification: the code 0445120265 and the Weichai number 612630090001 are stamped on the body, and that is the same identification a diesel injector rebuilder reads before ordering.
Cross-Reference & Interchanges
Need a 0445120265 cross reference or a 0445120265 equivalent? The Bosch CRIN2 interchange numbers below are the ones buyers match against. All are reference interchanges only.
For an injector cross reference, the Bosch 0 445 120 265 number is the reference and this 0445120265 bosch replacement is a Vidishi Auto compatible unit. Run a 0445120265 cross reference against the etched code, or look for a 0445120265 equivalent, and both resolve to the same CRIN2 assembly: the Weichai OE 612630090001 and 612630090028 plus the related reference 0445120086 and the exchange number 0986AD1016. Those numbers are published so a buyer can match the correct replacement; we are an independent supplier, not a Weichai or Bosch distributor.
Key Features
Why the 0445120265 CRIN2 unit is built for Weichai WP12 / WP10 service.
CRIN2 high pressure injector
Rated to the CRIN2-16 class, 1600 bar, for precise metering under full load on 12 L and 10 L heavy-duty diesels.
Complete unit, not a tip
The whole solenoid injector is supplied — a direct replacement for the Weichai WP12, WP10 and WD10 engine.
Built for duty cycle
Specified for long-haul and construction duty across HOWO, Foton Auman, JAC, DeLong, Beiben and Hongyan fleets.
New and warranted
Supplied new with a 12-month warranty against manufacturing defects.
Compatible brand
Vidishi Auto compatible replacement — reference interchanges only, not a genuine Bosch part.
Precise metering
Solenoid valve design for stable idle and clean combustion after a bench test.
The diesel injector technology here is CRIN2 solenoid common rail injector technology, a high pressure diesel injector built for 12 L and 10 L heavy-duty diesels. This bosch cri injector uses a solenoid valve injector for precise metering and is a precision diesel injector supplied new. Each unit is a bosch diesel injector reference built to the Bosch CRIN2 specification, so the same part works in trucks, gensets and construction machines.
Failure Symptoms
Common rail injector symptoms to watch for on a Weichai WP12 or WP10 engine, and the checks that separate a tired unit from a healthy one.
| Symptom | What it usually means |
|---|---|
| injector leakage | An internal leak loses rail pressure between injections and can coke the tip. |
| injector misfire | A weak or seeping unit drops combustion quality on one cylinder at idle and under load. |
| injector failure | Long service wears the valve seat; the unit loses calibration before it stops. |
| black smoke diesel engine | Poor atomisation from a worn spray raises soot and exhaust opacity under load. |
| hard start injector | Low cranking compression on one cylinder or a leaking seat delays start-up. |
| injector fault code | An ECU cylinder-balance or circuit code points to one unit for a bench test. |
| weak spray pattern | A worn cone shows an uneven, narrow spray rather than a clean fan on the tester. |
Two measurements do most of the work: an injector return flow test against the CRIN2 spec, and a bench spray and seat-leak check. Bad injector symptoms and diesel injector symptoms rarely point to the injector alone — contamination past the filter, and a high-pressure fuel injection pump shedding debris, repeat the same damage, so fix the root cause as well as the unit. Some ECU generations store an injector coding value that must be written after replacement. If you are chasing a cylinder-balance code rather than a mechanical fault, start from the fault code library before pulling the unit.
How to replace common rail injector on a Weichai WP12 / WP10
A bench-side walk-through of injector installation for the 0445120265, from a single injector replacement to a full bench test.
Confirm the code
Match the etched 0445120265 / 0 445 120 265 and the Weichai engine code plate before removal.
Relieve pressure
Depressurise the common rail and isolate the battery before opening the fuel lines.
Remove and inspect
Unbolt the old unit, fit a fresh copper seal, and check the bore and seat for scoring or debris.
Fit to injector torque
Seat the new 0445120265 to the clamp torque spec with a clean seal; never reuse a washer or over-torque the clamp.
Purge and code
Bleed air from the fuel line and write the injector coding value if the ECU generation requires it.
Bench-test
Run the bench test on spray pattern, seat leak and return flow before refitting.
Use an injector removal tool and an injector tester to confirm spray and seat, and torque to the injector torque spec with a fresh copper washer. A common rail injector replacement on a WP12 or WP10 needs a clean high-pressure line and a new seal every time, and the injector installation is not finished until the correction value is written where the ECU requires it. Part numbers and service notes for the family sit under our installation guides.

Buyer Feedback
Field notes from workshops and fleets running the 0445120265 on Weichai WP12 and WP10 engines.
Matched the old 0 445 120 265 on our HOWO A7 WP12; smooth idle and clean combustion after a bench test. Compatible part, not an original Bosch unit — exactly what we needed for the price.
Two units replaced tired injectors on Foton Auman tractors; rail pressure restored and smoke dropped. Every unit passed an injector quality check and a diesel injector test before dispatch.
