Product Details
DLLA147P2474 Injector Nozzle by the Numbers
Identity and fitment data for the 0 433 172 474 nozzle, verified against multiple independent sources.
Each DLLA147P2474 nozzle is a bare spray component, not a complete injector: it is bench-fitted into a 0445120391 CRIN2-16 injector body and then serves the Weichai WP10, WP12, WP13, WD10 and WD615 engines fitted to trucks and construction machinery. The 04-series injector is only the parent unit — this listing is the nozzle inside it.
Vehicle Compatibility for DLLA147P2474
The nozzle serves the same engines as the 0445120391 parent injector: Weichai WP10, WP12, WP13, WD10 and WD615. Match the engine code plate and the etched number on the old nozzle before ordering.
| Engine | Series | Typical application | Nozzle |
|---|---|---|---|
| Weichai WP10 | 10 L | Heavy trucks, construction | DLLA147P2474 |
| Weichai WP12 | 12 L | Heavy trucks, tractors | DLLA147P2474 |
| Weichai WP13 | 13 L | Heavy haulage | DLLA147P2474 |
| Weichai WD10 | 10 L | Industrial, machinery | DLLA147P2474 |
| Weichai WD615 | Steyr-based 10 L | Legacy heavy duty | DLLA147P2474 |
The Weichai WP10 nozzle position is the most commonly confirmed application, and the same 0445120391 injector family carries the nozzle into the Weichai WP12 engine, the Weichai WP13 engine, the Weichai WD10 engine and the Weichai WD615 engine. Buyers arrive with either a Sinotruk HOWO nozzle request or a Foton Auman nozzle request, since both truck ranges use the same Weichai engine family. If your paperwork shows the 0445120391 injector, the nozzle inside it is this one.

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 WP10, WP12, WP13, WD10 or WD615, not another Weichai family.
- Photo of the old nozzle — the number stamped on the nozzle body, so we match the etched code and not just the engine.
About the DLLA147P2474 Nozzle
What a common rail injector nozzle is, and how it sits in the Weichai fuel system.
What a common rail nozzle does
This spray-generating part sits at the very tip of the injector. On this engine family the diesel common rail nozzle receives fuel from the rail at high pressure, the needle valve lifts for a controlled window, and the fuel is atomised into the combustion bowl. The diesel injector nozzle therefore decides the shape of the flame, not the quantity of fuel delivered.
How it fits the CRIN2-16 platform
On a CRIN2-16 injector the nozzle is clamped under the injector nut and lapped to the body so the needle seat seals. That assembly then works inside the common rail injection system of the engine, where the ECU controls injection timing and the nozzle simply delivers the spray. Rebuilding an injector almost always starts with the injector nozzle holder, the clamp sleeve that carries the nozzle into the body, and the DLLA147P2474 common rail nozzle is the part that gets renewed in that rebuild.
Sometimes the same part is indexed in a trade catalogue as diesel nozzle parts or under the wider group of injector nozzle parts; the DLLA147P2474 itself is the nozzle, not the holder and not the injector. It is supplied new under the Vidishi Auto brand as a compatible replacement, built to the Bosch DLLA P-code specification, with no claim of Bosch manufacture.

Reference figures come from the Bosch 0433172474 interchange and the 0445120391 CRIN2-16 parent unit, cross-checked across independent sources. Opening pressure, flow rate, hole count, needle lift, coil resistance and emission calibration are left as Not published because the manufacturer does not release them for the nozzle as a separate service part; those values are read on a test bench, not assumed from a generic common-rail figure. Bare nozzle dimensions are given as an approximate reference, while the 10 × 10 × 10 cm size and 2.000 kg weight are the packaged shipping values used for freight.
Cross-Reference & Interchanges
Need a DLLA147P2474 cross reference or a DLLA147P2474 equivalent? The numbers below are the ones buyers match against. All of them are reference interchanges only.
Any injector cross reference you find for the parent unit leads back to the DLLA147P2474 nozzle for 0445120391: the bosch 0 433 172 474 marking appears on the nozzle body as a Bosch interchange and never as an origin claim. If a supplier quotes a different nozzle code for the same injector, the injector has been built to a different specification and the parts will not interchange.
Key Features
Why the DLLA147P2474 is the nozzle workshops fit when they rebuild a CRIN2-16 injector.
CNC-machined spray geometry
The nozzle spray pattern is controlled by a machined needle seat and tip, which is what restores a clean cone on a rebuilt injector.
Correct 147-degree cone
The 147-degree angle matches the combustion bowl of the Weichai WP-series engines, so the flame does not impinge on the piston crown.
Fits the common rail injector nozzle holder
The nozzle drops into the 0445120391 injector body and is clamped under the standard clamp sleeve and nut.
Fits with standard consumables
Rebuilds using this nozzle also take a standard injector seal ring and standard fuel injector o rings, both available on the same RFQ.
Protected tip
Each nozzle tip is shipped in a sealed protective tube, so the lapped seat arrives exactly as it left the bench.
Compatible brand
Vidishi Auto compatible replacement built to the Bosch DLLA P-code specification — reference interchanges only, not genuine Bosch.
Failure Symptoms
Bad injector nozzle symptoms to watch for on a Weichai heavy-duty engine, and the checks that separate a tired nozzle from a healthy one.
| Symptom | What it usually means |
|---|---|
| Rough idle and misfire | An injector misfire on one cylinder points at a nozzle that no longer atomises evenly at low delivery. |
| Black smoke under load | Incomplete combustion from a poor cone gives black smoke diesel engine behaviour, especially on a climbing truck. |
| High return flow | An injector leakage path past the needle seat raises return volume and starves the rail of pressure. |
| Wet or dripping tip | Injector nozzle leakage shows up as a damp tip or a fuel smell in the oil long before the engine stops running. |
| Hard starting when hot | Worn spray geometry reduces cranking delivery, so the engine needs longer to fire. |
| Sooted tip and nozzle clogging | Varnish or debris narrows the spray, raising exhaust temperature and soot. |
| Fuel leakage diesel smell | A diesel trace around the injector bore usually means the seat is not sealing any more. |
| Fault code for one cylinder | An ECU balance code flags one injector failure candidate, so the nozzle is the first part to bench-test. |
Two measurements do most of the work: a return flow comparison against the other cylinders, and a bench spray and seat-leak check. Diesel nozzle symptoms rarely come from the nozzle alone — contamination past the filter, a high-pressure pump shedding debris and long service all repeat the same damage, so fix the root cause as well as fitting a new nozzle.
How to fit the nozzle on a CRIN2-16 injector
A bench-side walk-through of nozzle replacement, from pulling the injector to bench-testing the rebuilt unit.
Remove the injector
Use a fuel injector puller rated for CRIN2 clamps; a general-purpose injector puller or fuel injector removal tool can deform the body. Note the injector coding before removal.
Strip and clean
Hold the body and undo the nozzle nut with an injector removal tool, then clean the bore. Never mix needle assemblies between bodies.
Fit the new nozzle
Seat the DLLA147P2474 nozzle and needle, fit a new injector seal ring, and torque the nozzle nut to the injector nozzle diesel specification for this family.
Adjust and code
Where the injector allows adjustment, set the needle lift on the injector tester. Then write the injector coding value if the ECU generation requires it.
Bench-test
Run the assembly on an injector tester for spray shape, seat leak and return flow before the injector installation goes back into the engine.
A cheap injector puller is the usual cause of a bent clamp, and an over-torqued nut will distort a new nozzle as fast as the old one failed. Work clean, use fresh sealing washers and a proper injector tester, and record the coding value so the ECU sees the injector it expects.
Warranty & Support
Every DLLA147P2474 nozzle is covered against manufacturing defects, handled against the batch number on the box.
Manufacturing defects are covered from the ship date, and claims are handled against the batch number recorded on the box.
Cover runs for twelve months at component level, which is the standard common rail injector nozzle warranty offered on this trade part.
Contaminated fuel, water in the system, incorrect fitting, or a root fault elsewhere in the fuel system.
Send the batch number and the bench report and we process the warranty claim; the full procedure sits on the Warranty Policy page.
Wholesale & Bulk Supply
As a nozzle manufacturer and injector nozzle supplier we ship to importers, workshops, fleets and injector rebuilders. Send one RFQ for a fuel injector nozzle supplier quote, from four pieces to a container.
A common rail injector nozzle wholesale order starts at four pieces, so a workshop can trial the nozzle before committing to volume.
Diesel nozzle bulk export shipments are consolidated with other injectors for sale on the same invoice, which keeps freight per part low.
Send quantity and destination port and we return price, MOQ and lead time in one message, normally within 24 hours.
Commercial invoice, packing list, HS code documentation and a tracking reference travel with every consignment.
Shipping & Packing
Export packing and freight for single tubes through container volumes, quoted per order.
Orders move by express courier or air for small boxes and by sea freight for bulk pallets, always with tracking.
Each unit ships in a sealed protective tube inside a 10 × 10 × 10 cm export carton at 2.000 kg gross, foam-lined against transit shock.
Commercial invoice, packing list and HS code documentation are issued with the shipment so clearance does not hold the consignment.
Buyer Feedback
Field notes from workshops and fleets rebuilding CRIN2-16 injectors with this nozzle.
Matched the etched number on our old nozzles exactly. A diesel injector nozzle check on the bench showed a clean cone and no seat leak after the rebuild — compatible part, not a Bosch unit, which is what we wanted at the price.
Four pieces rebuilt a full set on a WD615 generator; smoke dropped and rail pressure held. Packed in tubes, arrived intact, and the RFQ came back the same day.
