The genuine XCMG Ts injector 800172372 is a high‑precision fuel injection unit designed for the Mercedes‑Benz OM460LA diesel engine powering XCMG articulated dump trucks. This Ts injector (common rail injector) delivers precisely metered, atomised fuel into the combustion chamber at pressures up to 2,200 bar, ensuring optimal power output, fuel efficiency, and emission compliance. Manufactured from premium heat‑treated steel with precision‑ground internal components, the 800172372 injector provides consistent performance under extreme mining conditions.
The 800172372 Ts injector features a fast‑switching solenoid valve, a precision‑machined nozzle with multiple micro‑orifices, and a pressure‑balanced design that maintains injection stability even at high load. The injector is fully compatible with the OM460LA’s common rail fuel system (PLD – Unit Pump System), delivering injection pressures that enable fine fuel atomisation and complete combustion. Using genuine XCMG Ts injectors eliminates the risks of poor spray pattern, coking, and excessive exhaust emissions associated with aftermarket units.
The 800172372 Ts injector is fully compatible with XCMG articulated dump trucks including the XDA30, XDA40, XDA45U, XDA60E, and XDA70 series. The XDA45U model is powered by a Mercedes‑Benz OM460LA inline 6‑cylinder engine producing 360 kW (483 hp) at 1900 rpm and 2,300 N·m of torque at 1300 rpm. The injector is critical for the engine’s high‑pressure common rail injection system, which must operate reliably under heavy loads, steep grades, and extreme dust conditions found in mining and quarry applications.
The following table provides complete technical specifications for the XCMG 800172372 Ts injector, meeting all original equipment manufacturer standards for the Mercedes‑Benz OM460LA common rail injection system.
The 800172372 Ts injector is manufactured from high‑grade heat‑treated alloy steel with precision‑ground internal components. The nozzle body is case‑hardened to 60–64 HRC, providing exceptional wear resistance against high‑pressure fuel flow. The 7 micro‑orifices are laser‑drilled with a tolerance of ±0.003 mm, ensuring consistent spray penetration and atomization. The solenoid valve features a fast‑response armature that achieves opening times below 0.3 ms, enabling multiple injection events per cycle for refined combustion.
Every 800172372 injector is 100% tested on a certified injection bench. Tests include static flow calibration (520 cm³/30 s ±2%), dynamic flow linearity from 0 to 3.5 ms pulse width, leakage test at 2,000 bar (zero leakage), and spray pattern visualisation (high‑speed camera). Solenoid resistance and response time are verified. The injector is then cleaned and packaged in an anti‑corrosion sealed container, protecting it from moisture and dust until installation.
The OEM Ts injector 800172372 is a direct replacement for the original injectors in the Mercedes‑Benz OM460LA engine. The XDA45U uses six of these injectors (one per cylinder) to deliver fuel at pressures up to 2,200 bar. The Electronic Unit Pump (PLD) system controls each injector individually, enabling precise fuel metering for optimal power and low emissions. The injector must maintain consistent flow across the engine’s full operating range—from idle to 2,100 rpm and torque output up to 2,300 N·m.
The XDA45U’s permanent all‑wheel‑drive 6×6 system with 100% lockable differentials and hydraulic retarder (braking >600 kW) creates intense engine loading and high fuel demand. Genuine XCMG injectors maintain stable injection quantities even under these extreme conditions. Field data from Australian iron ore mines and Indonesian coal operations shows that genuine 800172372 injectors achieve service intervals of 8,000–10,000 hours with no loss of performance, while aftermarket injectors often show flow drift or coking by 4,000–5,000 hours.
Proper installation of the 800172372 Ts injector is critical for engine performance and longevity. Before installation, clean the injector bore in the cylinder head using a bore brush and solvent—any debris can damage the nozzle. Install a new copper sealing washer (supplied with the injector). Lubricate the O‑ring and the injector body with clean engine oil. Insert the injector gently, ensuring it seats fully. Install the hold‑down clamp and torque the bolt to 25 Nm plus 90° (quarter turn). Do not reuse hold‑down bolts—replace them with new genuine XCMG bolts each time.
Connect the high‑pressure fuel line (M14 × 1.5) and torque to 30 Nm. Connect the electrical connector (solenoid). After installation, bleed the fuel system and start the engine. Check for external fuel leaks. Using a diagnostic tool, verify injector correction values (flow balance) and adjust ECU calibration if necessary. A follow‑up inspection for injector noise or smoke should be performed after the first 50 operating hours.
The 800172372 injector has been tested to ISO 16940 (diesel injection equipment performance) and XCMG durability standards. High‑frequency endurance testing (500 million actuations at 2,000 bar) resulted in less than 2% flow drift and no visible wear on the nozzle or needle. Spray pattern testing using high‑speed imaging confirmed consistent cone angle and droplet size across the entire pulse width range.
Field trials on XCMG XDA45U trucks in Chilean copper mines and Australian iron ore mines involved 30 injectors over 10,000 operating hours. Genuine 800172372 injectors showed no flow degradation or coking; exhaust opacity remained below 0.5 m⁻¹. Aftermarket injectors tested under identical conditions exhibited flow drift exceeding 5% by 5,000 hours and nozzle coking leading to increased smoke and fuel consumption. Corrosion resistance of the injector body (zinc‑nickel coated) exceeded 500 h salt spray per ASTM B117.
Aftermarket injectors pose serious risks to engine performance, reliability, and emissions compliance. Non‑genuine injectors often have poorly machined nozzles, inconsistent solenoid characteristics, and insufficient heat treatment, leading to uneven spray patterns, flow drift, coking, and increased fuel consumption. The consequences include engine knock, excessive black smoke, loss of power, and potential piston damage from poor combustion.
Genuine XCMG 800172372 Ts injectors offer full material traceability from certified suppliers, documented flow calibration records, 100% solenoid response testing, and a 12‑month warranty. Each injector is batch‑tested for leakage, dynamic flow, and spray pattern using computer‑controlled injection benches. Using genuine XCMG injectors preserves your articulated dump truck’s engine warranty, reduces fuel costs, and ensures compliance with site emission regulations.
