Product Description
nozzle
The S.P series of long bore and pintle fuel injector 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.
The fuel injector couple consists of a precision-matched needle valve and valve seat, which is responsible for high-pressure fuel atomization control, with a tolerance of ≤0.001mm and a pressure of 300bar. It is made of nitrided steel with a hardness of more than HRC60 to ensure zero leakage for 500,000 injections. It is adapted to diesel common rail and in-cylinder direct injection systems to reduce the formation of carbon deposits, and the maintenance period reaches 100,000 kilometers.
Product Introduction
The P-type Fuel Injection Nozzle is a durable and high-performance nozzle widely used in mechanical diesel fuel injection systems. Known for its robust design and reliable atomization capabilities, the P-type nozzle is a popular choice for heavy-duty diesel engines operating in demanding environments. It features a precision-ground needle and nozzle body that deliver accurate fuel quantities at high pressure, ensuring efficient combustion and stable engine performance. The nozzle is designed to work with in-line fuel injection pumps and is commonly used in agricultural, industrial, and construction engines.

Robust Construction: Built from high-quality alloy steel with heat-treated surfaces for excellent resistance to wear and corrosion.
Consistent Spray Pattern: Provides precise atomization and spray angle, leading to better combustion, lower fuel consumption, and increased engine efficiency.
Simple Maintenance: Mechanical design allows for easy inspection, cleaning, and replacement without specialized tools.
Proven Compatibility: Designed to fit a wide range of traditional diesel engines using in-line pump systems.
Cost-Effective: Offers reliable performance at a competitive price, making it ideal for fleet maintenance and industrial applications.
Product Applications
The P-type fuel injection nozzle is widely used in:
Agricultural Machinery: Tractors, planters, threshers, and irrigation diesel engines.
Construction Equipment: Excavators, bulldozers, rollers, and cranes using older or mechanical diesel systems.
Industrial Power Units: Diesel generator sets, pumps, and compressors requiring rugged, low-maintenance fuel injectors.
Commercial Vehicles: Older model trucks and buses still relying on mechanical injection systems.
Marine Diesel Engines: Small to medium vessels using mechanically injected diesel systems.
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.
What is your MOQ?
100 pieces.
What is the main difference between a P-type nozzle and a common rail nozzle?
A P-type nozzle is designed for mechanical injection systems with fixed injection timing, while a common rail nozzle is electronically controlled and operates under higher pressures.
How do I know when to replace the P-type nozzle?
Signs include increased smoke, rough engine operation, poor fuel economy, hard starting, and reduced power. A professional inspection can confirm nozzle condition.
Can P-type nozzles be cleaned and reused?
Yes, they can often be cleaned and reused if not physically damaged. Ultrasonic cleaning is recommended for removing carbon deposits and fuel residue.
Are these nozzles compatible with biodiesel?
P-type nozzles can be used with low-percentage biodiesel blends (e.g., B5), but long-term use of higher blends may require special materials to prevent wear or clogging.
What is the typical service life of a P-type fuel injection nozzle?
With proper maintenance and clean fuel, a P-type nozzle can last up to 100,000 kilometers or 3,000–5,000 hours of operation.
