High-performance Common Rail Injector Assembly

The high-performance Common Rail injector assemblies produced by Huahui Oil Pump Company include three categories: S, P, and common rail series. They can be matched with vortex and direct injection diesel engines with cylinder diameters of 60-120 mm. They have low fuel consumption, low smoke, and good reliability., etc., basically covering medium and small power diesel vehicles and tractors. P series fuel injector is a new variety developed by our company. It is small in size and small in inertia, making it especially suitable for medium and small high-speed diesel engines. The high-pressure common rail series meets the emission requirements of Eurasian and National Fifth Countries and is efficient and energy-saving.

As a key fuel injection component of the engine, the injector assembly can cleverly disperse fuel into fine particles and inject it into the combustion chamber. It has a precise structure and excellent performance, ensuring full combustion of fuel, thereby improving the engine's working efficiency, enhancing power, saving fuel, and adapting to a variety of different types of engines.

 

Product Introduction

The High-performance Common Rail Injector Assembly is a precision-engineered fuel delivery component designed for advanced diesel engines. It plays a crucial role in controlling fuel injection pressure, timing, and atomization, all managed electronically via the common rail system. This injector is built to meet the demands of high-performance diesel engines, ensuring efficient combustion, lower emissions, and superior engine response. It supports high injection pressures (up to 2,500 bar or more) for maximum fuel efficiency and engine power.

 

Product Advantages

Advanced Fuel Atomization: Delivers finely atomized fuel for more complete and efficient combustion, leading to higher power output and reduced fuel consumption.

Electronic Control Precision: Integrated with ECU-based control for ultra-precise fuel metering and timing, supporting multiple injections per cycle.

Low Emission Compliance: Engineered to help meet or exceed emission regulations such as Euro VI, EPA Tier 4, and China VI through optimized combustion.

Long Service Life: Built with wear-resistant components, such as DLC (Diamond-Like Carbon) coatings and high-strength alloys, to endure harsh environments and extended use.

Noise Reduction: Smooth injection operation reduces engine knocking and operating noise, improving overall driving comfort and engine performance.

 

Product Applications

The High-performance Common Rail Injector Assembly is widely used in:

Passenger and Commercial Vehicles: Suitable for high-efficiency diesel cars, vans, buses, and long-haul trucks.

Industrial Equipment: Powers forklifts, compressors, and stationary diesel engines.

Construction Machinery: Excavators, loaders, and cranes relying on high-pressure diesel systems.

Agricultural Equipment: Advanced tractors and harvesters requiring clean and powerful combustion.

Marine Engines: Diesel propulsion and auxiliary engines for shipping and offshore operations.

 

FAQ

How many production lines in your factory?

5 production lines.

 

Can you design the equipment according to our size?

Yes.

 

What is the difference between a common rail injector and a traditional injector?

A common rail injector operates independently from injection timing and pressure, allowing precise control via electronic signals. Traditional injectors rely on mechanical timing, limiting flexibility and efficiency.

 

How do I know if a common rail injector is failing?

Common symptoms include hard starting, poor acceleration, rough idle, increased fuel consumption, and white or black smoke from the exhaust.

 

Can this injector be used in older diesel engines?

No, common rail injectors require a common rail system and ECU. They are not compatible with older mechanical injection systems without significant modifications.

 

How do I maintain the injector for optimal performance?

Use clean, high-quality diesel fuel, replace fuel filters regularly, and ensure the fuel system is free of contaminants. Periodic professional inspection is also advised.

 

Is remanufacturing or repair possible for this injector?

Yes, many high-performance injectors can be remanufactured if components are in good condition. However, OEM-certified repair services should be used to maintain performance and safety.
