Product Details
0445120392 CRIN2-16 by the Numbers
Verified identity and application data for the complete diesel common rail injector, supplied for the Wärtsilä range.
Each 0445120392 is a complete heavy duty diesel injector for the diesel common rail system rather than a bare spray tip: this CRIN2-16 injector carries the 0 445 120 392 reference on the body and is built to the Bosch CRIN2-16 specification. As a Wärtsilä industrial engine injector it serves stationary power generation, marine propulsion and auxiliary machinery, where duty cycles are long and the fuel is often heavy or high sulphur.
Engine Compatibility for 0445120392
This complete injector runs Wärtsilä industrial, marine and generator-set engines. It is a common rail injector for Wärtsilä installations rather than a light-duty automotive unit.
| Engine duty | Typical installation | Injector |
|---|---|---|
| Industrial engine | Stationary power, plant and process duty | 0445120392 |
| Marine engine | Vessel main and auxiliary machinery | 0445120392 |
| Generator set | Power plant and standby genset | 0445120392 |
| Heavy-duty stationary | Continuous-duty industrial drive | 0445120392 |

Most buyers arrive with a Wärtsilä parts number alone, so we keep the whole family in one place. Send the nameplate and we confirm whether the 0445120392 Wärtsilä injector is the one you need; the same reference is also listed as a common rail injector for Wärtsilä stationary and marine installations. The PAAF072206 OE number is the fastest way to shortlist the correct unit before you open the fuel system.
Fitment verification
- Engine code plate — the nameplate must read Wärtsilä, with the build year and rating, before we go further.
- Etched number on the old unit — 0445120392 or 0 445 120 392 stamped on the injector body, not just the engine number.
- Photo of the unit in place — connector pattern and body length, so we match the revision and not only the family.
About the 0445120392 Injector
What the complete CRIN2-16 unit is, and how it sits in an industrial fuel system.
What is a common rail injector?
A common rail injector is the solenoid unit that meters and atomises fuel from the rail into the combustion bowl. The 0445120392 is a complete common rail injector in the Bosch CRIN2-16 family: the whole injector, not just the 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 an industrial engine the control valve opens, the nozzle sprays, and the ECU trims each cylinder individually. A worn unit shows up as a weak cone or a seeping seat long before it stops running.
Common rail injector vs nozzle
Comparing the complete injector with its nozzle is really whole unit vs component. The injector is the complete assembly; the nozzle is one serviceable part inside it. A CRIN2 vs CRI injector comparison is different again: the CRIN2-16 is a heavy-duty 16 mm-body unit built for continuous industrial duty, while a light-duty CRI injector is a smaller road-going part with a different calibration and a far shorter service interval.
Where the CRIN2-16 platform sits
Internally the unit carries the Bosch F00RJ01704 control valve, shared with the rest of the CRIN2-16 valve family. It is built to the high pressure common rail standard used on modern industrial diesels, and supplied new under the Vidishi Auto brand as a compatible replacement. Treat it as a complete diesel injector for a diesel injector replacement job rather than a component swap.

Reference figures come from the Wärtsilä PAAF072206 OEM reverse lookup and Bosch CRIN2-16 component evidence; the 0 445 120 392 number is carried on the body as an interchange, never as an origin claim. Built to the Bosch CRIN2-16 specification and supplied as a compatible replacement with a 12-month warranty against manufacturing defects. Net weight is left as not published because sources conflict, so only the packaged shipping weight of 2.5 kg is stated. Pressure is a CRIN2-16 class rating, not a per-unit calibration value. Flow rate, coil resistance and opening pressure are quoted only after a bench run on injector testing equipment. This common rail injection system part is supplied as a compatible replacement, not a Bosch-branded original.
Cross-Reference & Interchanges
Need an 0445120392 cross reference or an 0445120392 equivalent? The numbers below are the ones buyers match against. The PAAF072206 cross reference, the 0 445 120 392 cross reference and the Bosch CRIN2-16 interchange are all reference interchanges only.
Inside the complete unit sits the Bosch F00RJ01704 valve, a component shared across the CRIN2-16 family of complete injectors. That valve is revision dependent, so a service part must be ordered against the complete injector number rather than the valve number alone. Related same-valve-family complete units exist across the CRIN2-16 range, and each is an independent part number — we list them as related units only and never write them as equal cross-references. If you are working from a Wärtsilä OE number, send it with the etched code and we will map it in one reply.

Failure Symptoms
Common rail injector symptoms to watch for on an industrial diesel engine, and the injector checks that separate a tired unit from a healthy one.
| Symptom | What it usually means |
|---|---|
| injector rough idle misfire | A weak or seeping unit drops combustion quality on one cylinder at idle and under load. |
| diesel injector black smoke | Poor atomisation from a worn spray pattern raises soot and exhaust opacity under load. |
| hard start injector | Low cranking compression on one cylinder, or a leaking valve seat, delays start-up. |
| high return flow injector | An internal leak raises return-line volume and starves the rail of pressure. |
| injector fault code | An ECU cylinder-balance or injector-circuit code points to one unit for a bench test. |
| common rail injector seat leak | A seeping needle seat loses rail pressure between injections and can coke the tip. |
| injector spray pattern weak | 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 CRIN2-16 specification, and a bench spray and seat-leak check. The common rail injector symptoms above are rarely the injector alone — contamination past the filter, a high-pressure pump shedding debris and worn valve seats from long service all repeat the same damage, so fix the root cause as well as the unit. Read stored codes first on fault codes, then bench the suspect unit.
How to replace common rail injector on an industrial diesel
A bench-side walk-through of common rail injector installation for the 0445120392, from a single injector replacement to a full bench test.
Confirm the code
Match the etched 0445120392 / 0 445 120 392 and the engine code plate Wärtsilä before removal, and record the unit position.
Relieve pressure
Depressurise the common rail and isolate the battery before opening any high-pressure fuel line.
Remove and inspect
Unbolt the old unit, fit a fresh injector copper seal washer, and check the bore and seat for scoring or debris.
Fit to common rail injector torque
Seat the new 0445120392 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 a bench test common rail injector check on spray pattern, seat leak and return flow before returning the engine to service.
Not sure how to test a common rail injector at home? A bench tester is the only reliable way to read opening pressure, cone shape and seat leak, and a road or load test will not separate a tired unit from a healthy one. A single injector replacement Wärtsilä fleets carry out in the workshop is fine when only one unit is worn, provided the others are within spec. Fit a fresh copper washer every time, torque to spec, and purge the line before the first start; full procedures sit in our installation guides.

Buyer Feedback
Field notes from workshops and operators running the 0445120392 on industrial and marine engines.
Matched the old 0 445 120 392 on a stationary genset; smooth running and clean exhaust after a bench-test. Compatible part, not an original Bosch unit — exactly what we needed for the price.
One unit replaced a tired injector on an auxiliary engine; rail pressure restored and smoke dropped. Fast RFQ turnaround and the box arrived intact.
