Precision fuel delivery for high-performance diesel engines – The OEM F1100-1112100-005 Fuel Injector Component is engineered to deliver precise fuel atomization and injection timing, optimizing combustion, reducing emissions, and improving fuel economy. Designed for SINOTRUK Homan common rail systems, this injector withstands pressures up to 2000 bar. For guaranteed compatibility and performance, always choose genuine Sinotruk Homan parts.
The F1100-1112100-005 features a multi-hole nozzle (8 holes, 0.18mm diameter) and a servo-hydraulic actuator for rapid response, providing consistent injection quantity across all cylinders even at high mileage.
The F1100-1112100-005 fuel injector uses a solenoid-actuated control valve with a hardened stainless steel ball seat, providing consistent opening and closing times (within 5 microseconds). This precision ensures that each injection event delivers exactly the commanded fuel quantity, eliminating cylinder-to-cylinder variation.
Unlike generic rebuilt injectors, this genuine SINOTRUK Homan component features a diamond-like carbon (DLC) coating on the nozzle needle, reducing friction and enhancing durability even with high-sulfur fuels. The result is improved fuel atomization, reduced smoke, and lower particulate emissions.
The injector body is made from high-strength alloy steel, heat-treated to withstand peak pressures of 2000 bar without deformation. The internal filter (20µm mesh) protects the precision clearances from fuel contamination.
Rated for injection pressures up to 2000 bar, compatible with Euro IV and V common rail systems. Delivers fine atomization for complete combustion.
Diamond-like carbon coating reduces wear and friction, extending injector life to over 500,000 km. Resists carbon buildup on nozzle tip.
8-hole nozzle with optimized spray angles for improved air-fuel mixing. Reduces combustion noise and lowers NOx formation.

The F1100-1112100-005 injector features a balanced servo-hydraulic system that minimizes internal leakage, resulting in faster pressure buildup and more consistent injection durations. The control valve uses a carbide ball paired with a lapped seat for zero-leak sealing when closed.
The nozzle needle is guided within a hardened sleeve with clearance of only 3-5 microns, ensuring precise centering and reduced wear. The DLC coating reduces friction coefficient to 0.1, compared to 0.6 for uncoated steel, dramatically reducing scuffing in high-pressure operation.
Each injector is individually calibrated on a Hartridge AVM2 test bench, with measurements taken across 12 different injection events (from 2 to 200 mg/stroke). The calibration code is laser-etched onto the injector body, allowing the ECU to compensate for minor variations.
All internal components of the F1100-1112100-005 are made from high-alloy steels that resist corrosion from bio-diesel and high sulfur fuels. The solenoid coil is encapsulated in a high-temperature polymer compound, protecting against moisture and vibration.
The nozzle is made from X40CrMoV5-1 tool steel, hardened to 60 HRC and tempered for toughness. The micro-sac design reduces dead volume, minimizing hydrocarbon emissions during engine start-up.
The F1100-1112100-005 is a direct swap for the original injector on SINOTRUK Homan common rail systems. It uses the same electrical connector (two-pin, waterproof), same clamp hold-down pattern, and same leak-off hose barb.
After installation, the ECU must be reprogrammed with the injector’s individual calibration code (via diagnostic tool). This ensures precise fuel metering. SINOTRUK Homan provides the calibration code printed on a label inside the box.
Proper installation of the F1100-1112100-005 is critical for performance. 1) Relieve fuel system pressure and disconnect the battery. 2) Remove the injector clamp and pull the injector out using a slide hammer (do not pry). 3) Clean the injector bore thoroughly – any debris will damage the new nozzle.
4) Lubricate the new injector body with clean diesel and install a new copper sealing washer. 5) Insert the injector, tighten the clamp to 25 Nm. 6) Connect the high-pressure line (torque 30 Nm) and leak-off hoses. 7) Reconnect electrical connector.
8) Prime the fuel system and use a diagnostic tool to enter the injector’s calibration code into the ECU. 9) Start the engine and check for leaks. 10) Run a cylinder balance test to verify correct operation.
The F1100-1112100-005 requires clean fuel. Always replace the fuel filter every 30,000 km and use high-quality diesel. Symptoms of a failing injector: rough idle, excessive smoke, increased fuel consumption, or diesel knock.
Common failure causes: contaminated fuel (water or dirt), DLC coating wear (from abrasive particles), or coil failure. Do not attempt to disassemble an injector – internal parts are precision-matched. If malfunction is suspected, have the injector tested on a professional calibration bench.
Always replace all injectors as a set for consistent cylinder balance. Mixing old and new injectors can cause torque fluctuations and ECU adaptations issues.
The F1100-1112100-005 injector is manufactured under IATF 16949 and ISO 14001 certified processes. Each injector undergoes 100% testing: static flow measurement at 2000 bar, dynamic flow measurement across 12 injection pulses, high-voltage coil insulation test, and leak test at 2500 bar overpressure.
Random samples are subjected to a 1000-hour endurance test on a hot engine (cycling between idle and full load), a 200-hour salt spray test (ASTM B117), and a vibration test (20g, 10-2000 Hz). The injector meets Euro V emission compliance standards as a replacement part.
A unique laser-etched QR code links to the individual calibration data. Counterfeit injectors often have fake codes, poor surface finish, or different solenoid resistance – always verify on the SINOTRUK Homan portal.
A fleet of 200 SINOTRUK T7H trucks operating in Kazakhstan (extreme cold, poor fuel quality) replaced all injectors with the F1100-1112100-005. Over 24 months, injector-related breakdowns dropped by 90%. Fuel consumption improved by 6%, and cold-start performance was notably better.
A construction company in Chile using HOWO dump trucks reported that after switching to genuine SINOTRUK Homan injectors, smoke opacity reduced by 70% and engine oil contamination (from blow-by) decreased significantly. The injectors showed no loss of flow after 15,000 operating hours.
Each genuine F1100-1112100-005 injector is supplied in a sealed anti-static plastic tube, then packed in a branded SINOTRUK Homan box. The package includes the injector, a new copper washer, a leak-off hose connector, and a calibration code card.
The injector body has a laser-etched OEM number, a batch code, and a 2D matrix code that links to the factory calibration report. Counterfeit injectors often have incorrectly machined nozzle tips or missing serial numbers. Always purchase from authorized dealers to avoid engine damage.
Using non-genuine injectors can lead to melted pistons, damaged turbochargers, or failed DPF regeneration – repairs that are far more expensive than the cost of original parts.
Summary: The SINOTRUK Homan Fuel Injector Component (OEM F1100-1112100-005) delivers exceptional precision, durability, and fuel efficiency for common rail diesel engines. Upgrade your injection system with this genuine component – trusted by fleets worldwide for reliable performance and lower emissions.
