Product Details
0445120345 Common Rail Injector by the Numbers
Verified identity and fitment data for this CRIN2 injector, supplied for the Deutz D8K engine range.
An injector is a different purchase from a control unit. The article arrives as a sealed CRIN2 injector with the nozzle and the solenoid already built in, so the job is a swap plus a coding step rather than a bench rebuild. Because the same 0445120345 hardware carries different calibration between engine revisions, one injector is matched by the number printed on its body, and a workshop replacing a faulty unit will order the exact body number rather than a machine-year guess. On the Deutz D8K platforms a single injector can be swapped without disturbing the rest of the fuel system, which is what makes per-cylinder replacement practical on a high-hour excavator.

Part number match
Match the number on your old injector to 0445120345, or to the spaced Bosch form 0 445 120 345. Where the machine is a Volvo excavator, the voe22263968 injector listing and the VOE21763511 number describe the same article through the Volvo parts system, and 04915316 walks the same path from the maker side.
A 0445120345 injector replacement is matched by the body number, so send a photo of the old injector if you are unsure. As a D8K injector this reference also covers the EC350D and EC350DL variants, because a Deutz CRIN2 injector for one machine is the same CRIN2 hardware for the others. A deutz injector, and specifically this D8K CRIN2 unit, is a diesel injector for the whole family, so a single body number spans the D8K range. An ec350d injector and a D8K injector fitment both share the same CRIN2 hardware, with no change to the injector itself.
The approach works the same whichever of those labels your own paperwork uses — the number on the body and the engine code are what we confirm, and a 0445120345 injector is the same article by whichever machine it is quoted.
Fitment verification
- Injector part number — match the etched code on the injector body to 0445120345, or to the spaced form 0 445 120 345.
- Engine code plate — the plate on the block must read a D8K engine, not another family.
- Photo of the old injector — a picture of the body marking and the engine code, so we match the revision and not just the model.
What a common rail injector does
On a diesel with the Bosch common rail system the injector is the final actuator that turns fuel pressure into a precisely metered spray.
On a diesel with the Bosch common rail system the injector receives high-pressure fuel from the rail and releases it into the cylinder on command from the engine control module. On the Deutz D8K diesels this is the CRIN2 solenoid injector, a solenoid diesel injector and common rail fuel injector in one body: the electronic diesel injector that bolts into the cylinder head and converts the rail pressure into the spray pattern the combustion needs. That makes it the point where the electronic side of the engine meets the hydraulic side — a diesel CRIN2 injector receives the trigger, opens the solenoid, and lets the metering valve set the quantity for every firing event.
The distinction that matters when buying is between a complete injector and the parts inside it. A bosch common rail injector of this family arrives sealed, built and coded; a repair is a bench job on the nozzle and valve, not a swap. Both routes exist on this platform and the choice is usually about bench time and warranty exposure rather than about the part itself. The crin2 injector and a compatible unit are described by the same words in a parts catalogue, so the two fields that settle the match are the number on the body and the calibration the ECU expects.
Metering
Releases injection quantity from the rail pressure set by the high-pressure pump.
Atomisation
Shapes the spray so the fuel burns evenly across the load and speed range.
Coding
Carries a calibration the ECU reads, so the injector is written in after fitting.
Because the injector is coded, the same physical part behaves differently depending on the data it carries. The Bosch CRIN2 injector is the actuator that holds that calibration, and an injector that has not been told which one it is driving will run with default maps. That is why a swap is a two-part job: fit the injector, then write the code. The engine will usually start either way, which is exactly what makes the second step easy to forget. When the choice is an injector repair or replace decision, the bench test settles it: a sound body is worth rebuilding, a contaminated one is not.
An injector on this platform is a robust design, and much of the failure comes from contamination at the nozzle or from a wiring fault rather than from the solenoid itself. The CRIN2 injector sits in the cylinder head, so an injector that has begun to drift shows as a stored fault code and a misfire behind it. Judging an injector on whether the engine still runs tells you almost nothing; judging it on the fault codes and the live data tells you nearly everything.
Two numbers worth separating: the article number identifies the injector you are holding, and the calibration code identifies how that individual piece should be mapped. An injector that carries the right number but the wrong software will still allow the engine to run, and the live data will look almost plausible — which is why we ask for both, and not the machine model.
Diesel, fuel or CRIN2 injector — three trade names
Which of those names a supplier writes on the offer depends on who is buying. A workshop ordering a replacement quotes the number on the old part. A dealer parts desk sourcing for a fleet quotes the engine code instead. A distributor stocking the CRIN2 range quotes the family. The article behind all three labels is the same injector, and so is the test that settles the match: the number on the body and the calibration the ECU expects.
That is the reason we ask for the article number rather than the machine model. Whether your own paperwork calls this a crin2 injector, a common rail injector for the Deutz D8K or simply a fuel injector for the CRIN2 range, the code on the part is what we confirm, and the code we ship against is the one you state. The common rail architecture here is the same Bosch reference design used across the D8K excavator families.

The line between a bosch crin2 injector and a compatible one is a line about branding, not about function. What the table above describes is a bosch CRIN2 injector built to the 0445120345 architecture: a sealed body, a solenoid, a nozzle and a calibrated metering valve. Because the injector is tested as a whole, the figures that matter most — calibration, flow and spray — are the ones the bench produces rather than the ones a catalogue quotes, which is why they are left unpublished here rather than filled in from a similar listing. A CRIN2 injector run on contaminated fuel will fail its nozzle long before the solenoid, so fuel quality is the largest single factor in how long a replacement lasts. Buyers comparing diesel injector assembly, fuel injector assembly and common rail injector assembly specifications across suppliers should expect the same set of published fields from each, and the same honesty about the fields nobody publishes.
CRIN2 injector, solenoid injector, fuel injector — what the terms cover
All three descriptions point at the same injector on this platform, and none of them narrows the specification. A counter serving workshops tends to write the part up with the shorter wording and quote the number on the old unit. A parts desk buying for a fleet writes it up with another and quotes the engine. What arrives in the box is identical either way: a bosch common rail injector built to the CRIN2 reference design.
What does change the specification is the calibration code, and the code is not written in the trade name. Since an injector carries a calibration the ECU reads, an incorrect or unwritten code will leave the new part running on default maps whatever the label on the carton says. That is a different failure mode from the older practice of grading a part by its description alone, and it is why we record both the article number and the coding step on the offer we send.
Common rail injector technology on this engine has been stable for well over a decade, which is what makes a complete replacement practical: the body, the connector and the mounting arrangement are shared across the production years, so the same injector fits engines built in different seasons. Where a buyer writes the order as a crin2 injector and the supplier lists it as a fuel injector, both are naming parts of the same build, and the injector that arrives is the whole article rather than a component.
Failure Symptoms
Common injector failure signs to watch for on the D8K diesel before an injector is replaced. Most common rail injector problems show first as a rough idle or a stored fault code rather than a hard no-start.
- Rough idle or a persistent cylinder misfire
- Hard starting or extended cranking
- Stored fault codes naming an injector circuit
- White or black smoke from the exhaust
- Elevated fuel consumption
- Knock or uneven combustion under load
- Loss of power on a specific cylinder
- Contamination found at the nozzle tip
Injector failure symptoms overlap with pump, sensor and wiring problems, and CRIN2 injector problems on this family are the same set of codes seen through a different lens, so a scan tool reading plus a live-data check is the normal way to isolate a single injector. Summaries of the stored codes are grouped on our diesel fault codes page, and the list above can be read alongside live data rather than trusting a guess. Diesel injector fault symptoms on this family usually present as a cylinder-specific misfire that points back at the injector, which is exactly the part this page describes.
Most CRIN2 injector problems on this engine start with fuel quality or contamination rather than with the solenoid. The classic giveaway is a misfire that follows a tank of poor fuel, then clears after the system is flushed. Letting the machine run on until the early signs turn into a hard fault rarely saves money, because an injector that has been killed by contamination will usually have taken the nozzle with it. A replacement should follow a confirmed diagnosis: read the fault codes, check the fuel and the harness, and only then commit to the injector the ECU is flagging. Renewing the fuel filter alongside the injector is worth considering on a high-hour machine, where the supply is usually at the same stage of wear.
Replacement and coding notes
Fitting an injector is a cleanliness-critical job with a second, electronic step that decides whether the engine runs properly. A correct common rail injector installation starts with clean fuel and ends with the calibration written into the ECU.
Confirm the code
Record the article number and the calibration on the injector you are removing before stripping anything.
Relieve pressure
Depressurise the common rail and work on a clean, dry bench to protect the nozzle and the connector.
Inspect the seat
Check the cylinder-head injector seat and the copper washer for carbon, corrosion or damage before fitting the new unit.
Fit and torque
Seat the injector squarely and torque the clamp to the figure your workshop data gives.
Write the code
Transfer or rewrite the calibration with a suitable scan tool before the engine is run in earnest.
Clear and test
Clear the fault codes, run to temperature and confirm live data before a working test.
An injector replacement on this engine is normally done in the vehicle rather than on the bench, because the injector is a complete article and nothing inside it is being opened. The cleanliness discipline still applies: the nozzle seat must be clean and the washer sound, or the new injector will leak or misfire. Where the job is being done as part of a fuel-system service, a fresh copper washer and a new seal are worth ordering at the same time.
Injector coding is the step most often missed, and a CRIN2 injector installation done without it will run rough even though the mechanical work was correct. Until the calibration is written in, the ECU will run on default maps. Help reading the values before and after is available through our fuel system maintenance notes, and the full sequence is set out in our injector fitting guide and installation notes.
Reference and interchange numbers
Need an injector cross reference or a 0445120345 equivalent? The numbers below are the ones buyers match against. All are reference interchanges only.
A 0445120345 cross reference lists the Bosch exchange number 0 445 120 345 alongside the Volvo numbers VOE22263968 and VOE21763511, so a buyer can match the injector by either route. A voe22263968 injector search returns the same CRIN2 article, which is why both routes are quoted together. Cross-checking against the Volvo number is safe only when the old injector or the machine parts book carries that number, and 22263968 is the short form of the same listing. A bosch injector number lookup is filed under both the exchange number and the Volvo numbers, so a search for a bosch 0445120345 listing and a search for the Volvo number lead to the same article. A plain injector interchange by internal number walks the same path from the other end, starting from the Bosch number rather than the machine one. Any bosch injector lookup that returns only the machine maker figure should be treated as incomplete, because the article number is what the supplier ships against. These numbers identify one article group; they are not a statement that this injector is an original-equipment part.
The body also carries a production marking alongside the article number, reproduced here only so a buyer can recognise what they are reading. The complete injector carries its own number and its own calibration code, and the table above deliberately stops at article level. If your old injector is stamped with a number that does not appear here, send us a photograph of the body before ordering and we will check it against the CRIN2 range. Where a listing gives an injector cross reference figure, check that it names the engine as well as the number, because an interchange written without the platform is not a match.
Two suppliers can quote the same article under different wording — one listing a replacement injector, another an exchange unit for the Volvo excavator range, a third a short maker number. None of those descriptions identifies the article on its own. The two fields that do are the full number and the engine the injector is built for, which is why we record both on the offer we send.
Build quality and inspection
Every injector is built and checked before it leaves us.
Each injector is built to the 0445120345 architecture used by the Deutz D8K diesels, so the body, the connector and the calibration match the injector it was built for. The nozzle, the solenoid and the metering valve are set as part of the build rather than added afterwards.
The internal numbers inside the injector are revision-dependent: confirm by the number on the body before ordering, because this engine can carry more than one revision across its production years. That is also why we take a photograph of the injector body rather than relying on a catalogue entry.
Injectors are checked electrically and for spray before they leave us. Where a workshop wants figures rather than a pass or fail, the injector can be run on a bench tester and the diesel injector test report supplied with the order. An injector remanufactured from a contaminated body is a different article from a new one, and this page describes a new injector; the test report is what lets a buyer see the difference in writing, and an injector inspection against the body number is part of that record.
Alongside complete injectors we hold related fuel-system parts for this family, so a rebuilder can service an injector instead of replacing it whole. Where a workshop is ordering an injector inspection rather than a complete injector, the internal numbers are confirmed against the body you send us.
Wholesale & bulk supply
Vidishi Auto is an export supplier of diesel fuel-system parts, serving workshops, rebuilders and distributors who service Bosch CRIN2 injectors in volume. Our common rail injector wholesale programme supplies single pieces through container quantities.
4 pcs, with tiered terms as quantity rises.
Matched batches for workshop stock and engine sets.
Each injector is carton-sealed for freight.
Our CRIN2 injector wholesale and diesel injector wholesale programme runs from a single piece through to container quantities, and as one of the injector suppliers serving export workshops we consolidate mixed fuel system orders into a single shipment. Where a workshop buys a few injectors at a time to cover a failed unit, the bosch injector price is quoted on tiered terms rather than on a single unit, and the effective CRIN2 injector cost per piece falls as the batch grows. Buyers who place a standing order usually want the same article from batch to batch, which is what our stock holding is arranged to give. Send your required quantity and destination port for a quotation. Tiered terms and lead times are on our wholesale pricing page.
Packaging, weight and shipping
Export packing and freight for single boxes through container volumes, quoted per order. The common rail injector cost is quoted per quantity, with the single-unit box packed for export.
20 × 5 × 5 cm.
1.2 kg gross per pack.
4 pcs.
Injector boxed, wrap, carton sealed.
The 20 × 5 × 5 cm pack is sized for a single boxed injector, so a small batch for the D8K machine range ships as a compact carton rather than a stack of oversize boxes. The packaged shipping weight is 1.2 kg gross per pack, which covers the injector, its connector cap and the sealed bag. Freight options and delivery estimates are set out on our shipping information page; returns and cancellations are covered under returns.
The injector cost for this reference moves with quantity and freight, so the figure that applies to your order is the one quoted and confirmed before dispatch. Whether you are comparing a quotation from a local distributor or a common rail injector cost from another exporter, ask for it to include freight and the warranty terms so the comparison is like for like. Where an injector is listed as an injector for sale at a headline figure, check whether the price is per piece and whether freight is included before you commit.
For a single injector the courier option is usually the fastest route; for a workshop quantity, a consolidated carton or a pallet brings the freight cost per piece down. Where a shipment is going to a resale address, ask for the commercial invoice and packing list to be issued with the dispatch documents so customs clearance is not held up at the destination.
