Premium-quality Howo Injector engineered for extreme durability. Trusted by fleets worldwide — experience zero compromise with certified Sinotruk HOWO components. Your journey to unmatched performance starts here.
The fuel injector is the heart of your diesel engine’s combustion system. A genuine Howo Injector ensures precise fuel atomization, consistent injection timing, and optimal power output. As part of our premium Howo truck parts lineup, each Howo Injector is engineered for WD615, D12, and MC series engines – delivering 1600–2000 bar injection pressure and multi‑hole nozzles for complete combustion.
Upgrading to new Howo Injector units reduces black smoke, restores fuel economy, and eliminates rough idling. Whether you operate a Howo T7H, A7, or TX, our injectors are 100% tested on Bosch test benches to meet OEM flow tolerances. Stop chasing power loss with cheap rebuilds – choose precision that lasts.
Multi‑hole nozzle (6–8 holes) with micro‑lapped orifices creates a fine fuel mist that mixes thoroughly with air, reducing unburned hydrocarbons and smoke.
Hydraulic or electronic (Euro V/VI) injectors maintain accurate start of injection across all RPM ranges, eliminating knock and maximizing torque.
Each Howo Injector is flow‑matched to within ±2.5% of the nominal value, ensuring equal cylinder contribution and smooth engine operation.
Designed for common‑rail systems up to 2000 bar (Euro V/VI) or unit pumps up to 1200 bar (mechanical). Wear‑resistant needle and seat for long life.

OE cross‑reference: For most Howo 7 / A7 with WD615.67/68 engines, use injector VG1246070035 (mechanical). For D12 engines: VG1540080042. For MC11/MC13 common‑rail: FS20123, 201V36001-0001. Always confirm by engine serial number.

Howo 7 / A7 / T7H (WD615, D12)
Mechanical injectors (VG1246070035 etc.) fit all Howo trucks with unit pump injection. Direct replacement for 336–420HP engines built before 2015.

T7H, TX, Sitrak C7H (MC11, MC13)
Common‑rail injectors for Euro V/VI engines. Also fits certain HOWO 2015+ models. Confirm injector type before ordering.
“Replaced all 6 injectors on my T7H with genuine Howo Injector. Idle is now smooth, black smoke gone, and fuel consumption dropped 12%. Worth every dollar.”
– Mikhail, Fleet Owner, Russia“We ordered a set of mechanical injectors for WD615. They arrived with calibration reports and all new copper seals. Engine runs like new again.”
– Carlos, Transport Manager, Peru“The common‑rail injectors for our MC13 were a perfect match. The online help with injector coding was excellent. Highly recommended supplier.”
– Li Wei, Workshop Supervisor, China“No more hard starting in the morning. These injectors restored full power to my old Howo 371. Fast shipping to Nigeria.”
– Ade, Owner‑Operator, NigeriaWhy a High‑Quality Howo Injector is Critical for Your Diesel Engine – Modern diesel engines depend on ultra‑precise injection. A worn or clogged injector can cause incomplete combustion, washing down cylinder walls, diluting engine oil, and damaging the DPF (for Euro V/VI). Our genuine Howo Injector units are manufactured using hardened stainless steel and diamond‑lapped nozzle seats to guarantee leak‑free operation. For common‑rail systems, the solenoid or piezo actuator response time is within 100 microseconds, enabling multiple pilot injections that reduce combustion noise. Mechanical injectors feature a two‑stage spring design that controls opening pressure precisely.
All units are shipped in sealed anti‑static packaging with new copper washers and o‑rings. We also provide injector removal tools and a special puller to avoid damaging the cylinder head. For large fleets, we recommend annual injector testing using our Bosch EPS 815 test bench service – we can test and report on flow, return leakage, and spray pattern. Upgrading to new Howo Injector units not only restores lost power but can improve fuel efficiency by 8‑15%. Protect your investment – install only genuine parts.
