Diesel engine injection nozzle

The S.P series of long bore and pintle diesel engine injection nozzle pairs produced by Huahui Oil Pump and Nozzle Company are suitable for 60 - 135 cylinder bore series diesel engines: the product performance is reliable, and its performance indicators rank among the top of similar products in China. It has been praised by users for many years. Quality trustworthy products.

As the core couple of the injector, the micron sealing surface is achieved through laser grinding, with atomized particles ≤20μm, and the fuel utilization rate is increased by 15%. It is temperature-resistant to 200 ° C and compatible with biodiesel. It is suitable for commercial vehicles, agricultural machinery and ship engines, and supports over 2,000 hours of bench test life.

 

Product Introduction

The Diesel Engine Injection Nozzle is a key component of the diesel fuel injection system, designed to deliver fuel into the combustion chamber in a fine, atomized spray. This ensures efficient fuel combustion, improved engine performance, and reduced emissions. Precision-engineered for both mechanical and common rail diesel engines, the nozzle plays a vital role in determining spray pattern, injection timing, and fuel quantity. Whether used in high-speed automotive engines or heavy-duty industrial machines, the diesel injection nozzle provides consistent and reliable operation under high pressure and demanding conditions.

 

Product Advantages

High Precision Fuel Delivery: Engineered for exact fuel atomization, resulting in complete combustion, improved fuel economy, and reduced smoke.

Durability Under Pressure: Manufactured from heat-treated, corrosion-resistant steel to withstand high injection pressures and harsh operating environments.

Consistent Spray Pattern: Designed to produce a stable, uniform spray for better mixing of fuel and air, maximizing combustion efficiency.

Emission Reduction: Supports cleaner engine operation by minimizing unburnt fuel and lowering particulate and NOx emissions.

Wide Engine Compatibility: Available in multiple configurations to fit various diesel engines, from light-duty vehicles to industrial power units.

 

Product Applications

The Diesel Engine Injection Nozzle is suitable for a broad range of industries and engine types, including:

Automotive Diesel Engines: Passenger cars, SUVs, light commercial vehicles, and heavy-duty trucks.

Agricultural Machinery: Tractors, harvesters, and diesel-powered irrigation pumps.

Construction Equipment: Bulldozers, excavators, loaders, and cranes that require durable and efficient fuel delivery.

Diesel Generators: Power generation units for industrial use, emergency backup, or remote applications.

Marine Engines: Small boats and vessels using mechanical or electronically controlled diesel engines.
