Fuel Injector 356-1367 3561367 Diesel Engine Fuel Injector 10r-1273 10r-9236 for C-at C32 C18c11c103406e

<Product Description>
This heavy-duty, electronically controlled unit-style diesel fuel injector assembly (Part ID: 356-1367 / 3561367; common OE cross-references include 10R-9257, 10R9257, 320-0680, 3200680, 20R-8054, 20R8054, etc.) is precision-engineered for the C6.6 ACERT / C7.1 ACERT inline-six diesel engine platforms. It is widely used in equipment such as the 320D2, 323D2, 326D2, and 329D2 series crawler excavators, 120M2 series motor graders, 950K / 962K series wheel loaders, and industrial emergency generator sets. As a key actuator within the electronically controlled high-pressure injection system—responsible for regulating diesel atomization quality and injection timing—it precisely meters fuel and rapidly disperses it into ultra-fine droplets in response to millisecond-level electrical signals, ensuring optimal mixing with intake air for efficient combustion.

Designed and manufactured to standards emphasizing "micro-level precision fit" and "millisecond-level rapid response," the component features a core solenoid valve and needle valve assembly crafted from aerospace-grade, hardened special alloy steel. These parts undergo ultra-precise geometric grinding and low-friction polishing, with surfaces finished in a dense, ultra-hard coating that effectively prevents internal scratching and pressure loss caused by fuel impurities. Upon installation, operators and technicians will notice immediate improvements: crisp, reliable cold starts and quiet, vibration-free idling. Whether climbing steep slopes, performing frequent stop-and-go maneuvers, or cruising over long distances, the throttle response is sharp and agile, and acceleration is robust yet smooth. Additionally, the injector reduces black smoke emissions, delivering satisfying fuel efficiency and a stable, refined driving experience. </Product Description>

<Product Advantages>
**Standardized Smart Manufacturing & Quality Control from the Source.** We effectively reduce procurement costs by eliminating issues common to intermediary distribution—such as excessive component tolerances, uneven fuel delivery across cylinders, and high-pressure leakage risks. Leveraging a standardized production base, we implement end-to-end quality control and remove unnecessary markups. This ensures highly consistent fuel injection pressure and flow rates across all cylinders, providing reliable power for vehicle and equipment operations while cutting maintenance budgets.

**Rigorous Testing on Ultra-High-Pressure Digital Dynamic Test Benches.** We address common problems associated with low-quality replacements—such as response lag, pressure-relief valve sticking (causing engine misfires and vibration), and wasted labor/costs from repeated installation and adjustment. Every injection component undergoes automated testing before leaving the factory; flow rates and sealing integrity are precisely calibrated across various pressure ranges in environments simulating real-world high-temperature, ultra-high-pressure conditions. This ensures "ready-to-install" performance, drastically saving time and costs associated with equipment disassembly and tuning.

**Large-Scale Warehousing & Rapid Shipping Response.** We recognize that vehicles and machinery are high-utilization assets; fuel system failures can lead to costly downtime and operational losses. Our warehouse maintains ample stock year-round. Upon order confirmation, items are quickly packed and shipped within 24–48 hours. This significantly shortens logistics wait times, helping fleet operators and equipment owners quickly restore operations and avoid losses caused by downtime.

**Special Quenched Alloy Needle Valves & Wear-Resistant Hardened Coatings.** We address issues where poor diesel lubricity or high sulfur content causes premature wear and valve sticking in precision components. Our core components utilize high-hardness special bearing steel and advanced anti-corrosion surface treatments. This results in superior fatigue and wear resistance, ensuring stable performance even under harsh conditions and prolonged high-load operation, thereby reducing the extra expenses associated with frequent repairs. </Product Advantages>

<Application Scenarios>
Open-pit mining and construction excavation: Medium-to-heavy crawler excavators operating continuously at mine sites and earthmoving projects often face prolonged periods of overload and high-dust environments. Maintenance teams install this injector assembly when equipment experiences slow starting, severe idle vibration, or stalling under heavy loads. Precise fuel atomization enables the engine to deliver strong torque at low RPMs, ensuring stable performance under heavy-duty conditions. Heavy-duty construction machinery and generator set applications: Feller-bunchers, wheeled loaders, and industrial emergency generator sets operating continuously in the field face high loads and harsh environments. When equipment experiences slow starting, sluggish performance under load, or a noticeable increase in black exhaust smoke, technicians can install this high-specification fuel injection component. Its robust and stable fuel delivery ensures the engine produces consistent torque, guaranteeing uninterrupted operation.

Q: Can the product be used immediately after installation, or is a correction code required?
A: Each fuel injector undergoes parameter calibration during factory testing. After installation, we recommend tightening to standard torque specifications and using diagnostic equipment to program the calibration code into the engine control unit (ECU) to achieve optimal fuel efficiency and smooth operation.

Q: What are the stock levels and lead times for bulk orders?
A: We operate our own factory and large-scale warehouses, maintaining substantial, year-round inventory for this model. Standard orders are packed and shipped within 24–48 hours, while bulk orders can be quickly scheduled for production.

Q: How are product quality and performance ensured before shipment?
A: All fuel injectors are assembled in a Class 100 cleanroom environment and undergo 100% bench testing across all operating conditions. Tests cover critical metrics such as sealing integrity, pre-injection volume, full-load injection volume, and fuel return volume; our rigorous standards ensure that every unit shipped is a high-quality product.

Q: What is the warranty period, and how is after-sales support handled?
A: We offer a 12-month warranty. Should a performance failure occur due to non-human factors during the warranty period, we provide rapid replacement or technical support to ensure you have complete peace of mind.
