Diesel engine nozzle fuel injector

The diesel engine nozzle fuel 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 diesel engine nozzle fuel injector assembly is the core link of engine fuel supply. It carefully designs the injection method to accurately inject fuel into the engine combustion chamber. Fine workmanship and excellent performance ensure full combustion of fuel, enhance engine power, and reduce energy loss. It is suitable for all types of engines and has excellent practicality.

 

Product Introduction

The Diesel Engine Nozzle Fuel Injector is a vital precision component in diesel engine fuel systems, responsible for delivering atomized fuel directly into the combustion chamber. The nozzle ensures a finely controlled spray pattern, optimizing combustion efficiency and engine performance. This injector is engineered to meet the demands of both modern high-speed engines and traditional mechanical systems. Designed for high durability, accurate injection, and fuel efficiency, it plays a crucial role in reducing emissions and enhancing power output in diesel-powered machines.

 

Product Advantages

Precise Fuel Atomization: Advanced nozzle design ensures consistent spray angle, droplet size, and fuel distribution for clean and efficient combustion.

High Pressure Tolerance: Built to withstand the high pressures of modern diesel systems, up to 2,000+ bar in common rail applications.

Durable Construction: Manufactured from high-grade stainless steel and alloy materials with anti-corrosion and wear-resistant coatings.

Reduced Emissions: Supports cleaner combustion processes, helping meet global emission standards such as Euro VI, EPA Tier 4, and China VI.

Wide Compatibility: Suitable for a variety of engine sizes and types, from single-cylinder pumps to multi-cylinder common rail systems.

 

Product Applications

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

Automotive: Diesel passenger cars, pickup trucks, commercial vans, and heavy-duty trucks.

Agricultural Equipment: Tractors, rice planters, harvesters, and irrigation pumps powered by diesel engines.

Construction Machinery: Loaders, excavators, graders, and other heavy equipment requiring robust diesel engines.

Power Generation: Diesel generators and stationary engines used for industrial and emergency backup power.

Marine Engines: Outboard motors and onboard diesel systems for fishing boats and commercial vessels.

 

FAQ

How many production lines in your factory?

5 production lines.

 

How long is your delivery time?

One week for spot goods, 60 days for orders.

 

Are you a trading company or a manufacturer?

Manufacturer.

 

What is your MOQ?

100 pieces.

 

What’s the role of the nozzle in a diesel injector?

The nozzle controls how fuel is atomized and sprayed into the combustion chamber. It directly impacts combustion efficiency, power output, and emissions.

 

How do I know if the nozzle or injector is worn or clogged?

Common signs include hard starting, increased fuel consumption, black smoke, loss of power, and engine knocking.

 

Can the nozzle be replaced separately from the injector?

In many cases, yes. Some injector types allow for nozzle replacement without replacing the entire unit, depending on the engine and injector design.

 

Are these injectors compatible with biodiesel or synthetic fuels?

Many models support B5–B20 biodiesel blends. Check the product specifications or consult your engine manufacturer for compatibility with alternative fuels.

 

How long do diesel nozzles typically last?

With proper fuel quality and maintenance, nozzles can last 100,000–150,000 kilometers or more. Regular inspections and fuel filtration are key to extending service life.
