0445110398 Common Rail Fuel Injector Nozzle 15710-68L00 for Suzuki Swift

Product Overview

This electronically controlled high-pressure common-rail diesel fuel injector assembly (Part ID: 0445110398 / 0 445 110 398; common OE cross-references include 0445110397, 0986435241, 03L130089A, 03L130089AX, etc.) is precision-engineered. Designed for the 2.0 TDI EA189 / CCHA / CCAA inline-four diesel engine platform, it is widely used in light commercial and crossover vehicles such as the Multivan T5/T6, Transporter, Amarok pickup, and Crafter light commercial vehicle. As a core component of the fuel supply system responsible for controlling diesel atomization quality and injection timing, it precisely meters high-pressure diesel and rapidly disperses it into ultra-fine particles—responding to millisecond-level electrical signals—to ensure thorough mixing and combustion with the intake air.

The component is manufactured to standards emphasizing "micro-level precision fit and millisecond-level rapid response." The core control valve spool and needle valve assembly are crafted from aerospace-grade, hardened special alloy steel, featuring ultra-precise geometric grinding and low-friction polishing. The surface is treated with a dense, ultra-hard coating that effectively prevents internal scratching and pressure loss caused by diesel impurities. Upon installation, drivers and technicians will notice immediate improvements: crisp, clean cold starts and quiet, vibration-free idling. Whether climbing steep slopes, navigating stop-and-go traffic, or cruising long distances, the throttle response is sharp and agile, and acceleration is robust yet smooth. Additionally, it reduces black smoke emissions, delivering satisfactory fuel efficiency and a stable, refined driving experience.

Product Advantages

• Cost-effective sourcing by eliminating intermediary markups. Standardized smart manufacturing and rigorous quality control directly from the source factory. By leveraging standardized production bases for end-to-end quality control and removing unnecessary middlemen, we ensure highly consistent injection pressure and flow rates across all cylinders. This approach not only cuts maintenance budgets but also provides reliable, robust power for vehicle and equipment operations.
• Rigorous testing on ultra-high-pressure digital dynamic test benches. Low-quality replacements often suffer from response lag and pressure-release malfunctions—causing engine misfires and vibration—as well as wasted labor and costs due to repeated installation and adjustment. Every injection assembly undergoes automated testing before leaving the factory; flow rates and sealing integrity are precisely calibrated across various pressure ranges in simulated high-temperature, ultra-high-pressure environments. This ensures "ready-to-install" performance, drastically saving time and costs associated with installation and tuning.
• Large-scale warehousing and rapid shipping response. Vehicles used for daily commuting and commercial transport are high-utilization assets; fuel system failures can lead to costly downtime and revenue loss. Our warehouse maintains ample stock, with orders packed and shipped within 24–48 hours of confirmation. This significantly reduces logistics wait times, helping fleets and owners quickly resume operations and avoid losses caused by vehicle downtime.
• Special-quenched alloy needle valves with wear-resistant hardened coatings. In regions where diesel fuel has poor lubricity or high sulfur content—factors that often cause premature wear and valve sticking in precision components—we provide a superior solution. Our core components utilize high-hardness special bearing steel and anti-corrosion surface treatments. These enhancements offer exceptional 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.

Application Scenarios & FAQ

Business MPV and Light Commercial Vehicle Intercity Commuting: Business MPVs and light commercial vehicles frequently travel between cities, often fully loaded with passengers and cargo, requiring exceptional idle stability and consistent power delivery. Mechanics should replace the full set of injectors if the vehicle exhibits slow starting, severe vibration at idle, or stalling under high load. After installation, the engine regains its quiet, smooth operation and delivers responsive, robust acceleration, ensuring a high-quality driving experience—even on long-distance trips.

Heavy-duty hauling scenarios for light pickup trucks and commercial vans: These vehicles often face complex road conditions and heavy loads at remote construction sites or during daily cargo transport. When drivers notice sluggish acceleration during overtaking or hill climbing, a significant spike in fuel consumption, or excessive black exhaust smoke, the maintenance team can install this high-precision fuel injector. Its precise fuel delivery allows the engine to generate ample torque at low RPMs, easily handling the demands of heavy loads.

Q: Can the product be used immediately after installation, or does a correction code need to be entered?

A: Each injector is assigned a unique flow correction code (IMA/QR code) during factory testing. We recommend using a diagnostic tool to program this code into the engine control unit (ECU) after installation to ensure optimal fuel efficiency and smooth operation.

Q: What are the stock levels and shipping 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 typically 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 injectors undergo assembly in a Class 100 cleanroom environment and 100% bench testing across all operating conditions. Tests cover critical metrics suchs as sealing integrity, pilot 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. If a performance failure occurs due to non-human factors within the warranty period, we provide rapid replacement or technical support to ensure a worry-free experience.
