Product Details
Assembly 1015572667 functions as a fully integrated electronically governed common-rail injector (not a bare DLLA tip, not a mechanical KDAL/KDEL holder) engineered for Weichai WP10/WP12 and Sinotruk HOWO D10/D12 Euro-III/IV drivetrains. It consolidates the solenoid actuator, valve control unit, high-pressure connector, needle guide, and DSLA-class 7-hole micro-sac tip into one screw-in cartridge that seals against the cylinder head via a 24 mm class flange and OEM copper washer. Rated for 1600 bar peak rail pressure (CRIN2 architecture), it delivers a 150° class hollow-cone plume through a 7×0.18 mm orifice array. Solenoid dwell and pilot-injection logic are calibrated to Weichai EMS3 / HOWO EDC17 baselines. Construction employs nitrided 16MnCr5 steel with a lapped 59° needle seat; the two-pin connector and return-fuel elbow follow Weichai harness geometry, not Bosch passenger-car pinout. Cross-reference aliases: GZWWPB1015572667, occasionally shelf-crossed to Bosch 0 445 120 215 / 0 445 120 225 class in aftermarket books.

Our Advantages
Optimized internal flow passage layout realizes rapid fuel pressure response, unlocking sustained torque output across wide rev ranges while cutting idle and cruising fuel consumption. Every unit undergoes independent dynamic testing on professional calibration benches to verify opening pressure, sealing performance and spray pattern, ensuring uniform performance consistency without batch discrepancies.Engineered for direct plug-and-fit replacement matching original mounting dimensions, it requires no extra modification during on-site overhaul and shortens equipment downtime significantly. Robust structural design accommodates long-term operation on heavy haulage trucks and stationary diesel power units. We maintain sufficient spot inventory to support small trial orders and bulk export shipments alike, with customized logistics solutions and long-term technical consultancy available through verified regional distribution partners.
FAQ
1.Is 1015572667 the nozzle tip, the holder, or the whole common-rail injector?
Whole common-rail injector assembly. Unlike the 131-series Bosch P-type tips (043213xxxx) or the CAT 212-8470 unit injector discussed earlier, this is a solenoid CR injector - it includes the electrical solenoid, valve stack, and tip. You do not separately buy a DLLA/DSLA element or a KDAL-style body; the 1015572667 carton is the drop-in unit.
2.Can a Bosch 0 445 120 215 be substituted for 1015572667 without recalibration?
Mechanically yes - flange, washer, and high-pressure nipple match; the Bosch CRIN2 body is the OEM donor. But Weichai/HOWO flash the solenoid trim code and pilot maps to the 1015572667 label; fitting a bare 0 445 120 215 without transferring the trim code or resetting the ECU injector balance codes yields rough idle and soot spikes. Bench the donor to identical crack/return specs, then write the IMA/QR code into the ECU - don't assume "same Bosch body = plug-and-play".
