Diesel engine fuel injector

The 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.

The injector assembly is a key executor of engine fuel injection. It injects fuel into the combustion chamber in an ideal state, helping fuel and air fully blend. The manufacturing process is excellent and the quality is reliable, which can significantly improve the combustion efficiency of the engine, improve power, and play an important role in various engine equipment.

 

Product Introduction

The Diesel Engine Fuel Injector is a core component of diesel fuel systems, responsible for delivering fuel into the combustion chamber in a finely atomized spray. It ensures optimal combustion by controlling the timing, pressure, and quantity of fuel injected into the engine. Designed for reliability and performance, this injector is suitable for a wide range of diesel engines, including mechanical and electronically controlled systems. Its durable construction and precision engineering contribute to improved engine efficiency, lower emissions, and prolonged service life.

 

Product Advantages

Efficient Fuel Atomization: Delivers precise fuel spray patterns to enhance combustion and power output.

Robust Durability: Made from high-grade, wear-resistant materials to withstand high pressure and heat over long periods.

Versatile Compatibility: Available in various designs to fit different engine types—mechanical, electronic, and common rail systems.

Lower Emissions: Supports cleaner combustion, reducing smoke and harmful emissions to meet modern environmental standards.

Easy Replacement & Maintenance: Designed for straightforward installation and servicing, minimizing vehicle downtime.

 

Product Applications

The Diesel Engine Fuel Injector is widely used across multiple industries, including:

Automotive: In diesel-powered passenger cars, SUVs, light-duty, and heavy-duty trucks.

Construction: Excavators, bulldozers, road rollers, and cranes that demand high power and reliability.

Agriculture: Tractors, harvesters, and irrigation equipment running on diesel engines.

Industrial Power: Diesel generators, compressors, and stationary engines for backup or continuous power supply.

Marine: Diesel propulsion systems in boats, fishing vessels, and cargo ships.

 

FAQ

How many production lines in your factory?

5 production lines.

 

Are you a trading company or a manufacturer?

Manufacturer.

 

What is your MOQ?

100 pieces.

 

How does a diesel injector differ from a gasoline injector?

Diesel injectors operate at much higher pressures and inject fuel directly into the combustion chamber, whereas gasoline injectors typically operate at lower pressures and often inject fuel into the intake manifold.

 

What are signs of a faulty diesel fuel injector?

Common symptoms include hard starting, rough idling, poor fuel economy, increased exhaust smoke, and engine misfire.

 

How long does a diesel fuel injector last?

Depending on fuel quality and engine conditions, a diesel injector typically lasts between 100,000 and 150,000 kilometers (or 3,000–5,000 hours of operation).

 

Can I clean a clogged injector myself?

While some fuel additives claim to clean injectors, professional ultrasonic cleaning or replacement is often required for severe clogging or wear.

 

Is this injector compatible with biodiesel?

Many modern diesel injectors are compatible with biodiesel blends (e.g., B5, B20). However, check manufacturer specifications to ensure fuel compatibility.
