2264458 Auto Spare Parts Car Accessories 2264458 Fuel Injector for Excavator

This high-pressure electronically controlled injection valve assembly (standard part number: 2264458, common interchangeable and cross-reference part numbers include 226-4458, 2264458OR, etc.) is specifically designed for heavy-duty commercial trucks, construction machinery, and high-load diesel power systems. It is a key actuator for achieving high-pressure micro-metering and rapid atomization of diesel fuel. The product is widely installed in long-haul trucks, large-tonnage engineering dump trucks, special-operation excavating equipment, and standby diesel generator sets.

This product adheres to the R&D and manufacturing standards of "multi-hole rapid atomization and high-pressure ultra-micro spray." The internal valve needle assembly and electromagnetic response valve core undergo high-precision grinding and polishing, and the surface is covered with an anti-coking hardening coating, effectively preventing early erosion caused by impurities in inferior diesel fuel. After the equipment is upgraded, drivers and machine operators will experience significant changes: cold starts are quick and smooth, and the severe shaking and vibration at low idling speeds are completely eliminated; under heavy-load climbing steep slopes or high-intensity continuous tunneling conditions, throttle control is tight and smooth, power is continuous and powerful, and exhaust smoke is significantly reduced, resulting in excellent fuel economy for vehicles and machinery.

Long-haul logistics and steep mountain climbing: In cross-regional logistics transportation, trucks fully loaded with heavy goods face long-term high-speed cruising and continuous steep slope climbing. By replacing the fuel injector with this high-pressure injector, drivers can clearly feel that the vehicle's upshifting and acceleration are more crisp, and the power output is full and does not diminish when the accelerator is pressed. At the same time, it promotes complete combustion of diesel fuel, improving climbing torque while effectively reducing overall fuel consumption.

Construction and continuous operation of large heavy-duty machinery: In construction sites with high dust and harsh terrain, heavy equipment frequently operates under high load. This injector, with its microsecond-level electronic control response and ultra-high pressure atomization capability, ensures that the engine can still output continuous high torque even when facing drastic fluctuations in speed. The compound action is smooth and continuous, completely avoiding engine stalling and misfiring, ensuring efficient progress of construction.

Q: Can I use the product directly after installation? Do I need to enter a correction code?

A: Each injector has a unique flow correction code (IMA code) generated during factory testing. It is recommended to use a diagnostic tool to flash the correction code into the engine ECU after installation to achieve optimal fuel efficiency and smoothness.

Q: What is the inventory and delivery time for bulk purchases?

A: We have our own factory and large warehouse, and maintain a large inventory of this model year-round. Standard orders can be packaged and shipped within 24-48 hours, and large-volume orders can be quickly scheduled for production.

Q: How do you guarantee the quality and performance of the product before it leaves the factory?

A: All injectors undergo Class 100 cleanroom assembly and 100% full-condition bench testing, covering key indicators suchs as sealing, pre-injection volume, full-load injection volume, and return volume. Stringent testing standards ensure that the product is of superior quality from the outset.

Q: What is the product warranty period? How is after-sales service handled?

A: We offer a 12-month quality guarantee. If a performance failure occurs during the warranty period due to non-human factors, we provide fast replacement or after-sales technical support to ensure your peace of mind.
