Common Rail Injector 1000160137 (Cross 0445120391 / 216004) — OE-Grade Fuel Control For Weichai WP13 Heavy Trucks

Hard hot-starts after a short fuel stop, light black haze when you pull away, and rail-pressure "hunting" at idle are classic signs of an injector that's no longer within spec. The 1000160137 common rail injector is an OE Weichai part number, catalogued together with Bosch 0445120391 and 216004 for use on Weichai WP13 heavy truck engines and related applications.crdiparts. 

If your parts book or old injector shows any of these codes - 1000160137 / 0445120391 / 216004 - this is the professional replacement to restore precise fueling on modern Weichai-powered vehicles.

 

 

Most professional catalogs list these numbers together on the same injector line:

Weichai P/N: 1000160137 (often tagged simply as "Common Rail Injector") 

Bosch-style reference: 0445120391ziedel. 

Other OE ref: 216004 

Typical description in listings: "Common rail fuel injector 1000160137, 0445120391, 216004 for Weichai engine / Weichai WP13." 

Fitment check tip: Match at least two numbers (e.g. 1000160137 on the invoice and 0445120391 on the injector body), and confirm against your engine data plate (WP13 / truck model) before ordering.

 

 

Weichai's WP13 is a 12.54 L inline-6 common-rail diesel used in medium and heavy dump trucks, with power in the 353–390 kW (480–530 hp) range and up to 2500 N·m of torque at low rpm. 

The 1000160137 / 0445120391 injector is specified in the aftermarket for:

Instead of generic "better performance" claims, focus your product page on three tangible outcomes fleet buyers recognise:

① Rail pressure stability
Worn injectors leak excess fuel back to the return line. That makes it harder for the rail to reach target pressure at crank and under sudden load. Bench-tested 1000160137 / 0445120391 injectors bring leak-off back within spec, helping the ECU hit its rail-pressure targets more quickly - especially noticeable as shorter hot-starts. 

② Finer atomisation & cleaner exhaust
A fresh nozzle with a clean spray pattern produces a stable, fine cone. Result: less grey smoke when the truck pulls away or the dump body climbs, and less stress on DPF / SCR systems where fitted. 

③ Balanced cylinders, smoother feel
Flow-matched injectors keep each cylinder contributing its share of power. Drivers experience smoother idle, less vibration, and more predictable fuel consumption over a full shift

To turn this injector into a real fix (and reduce comebacks), your product copy can outline a simple procedure:

Confirm the fault – perform a return-flow / leak-off test across all cylinders; replace only out-of-family injectors unless the whole set is worn 

Prepare the seat – clean the injector bore on the WP-series head; always install a new copper washer and O-rings.

Install and torque – fit the 1000160137 / 0445120391 injector to factory torque and avoid stressing the high-pressure line.

Prime & bleed – purge air from the system until rail pressure builds smoothly.

Verification run – check for faster hot starts, stable idle, cleaner exhaust under 1,000–1,400 rpm where dump trucks spend much of their time
