Product Description
fuel injector
The high-pressure 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.
The high-pressure common rail injector assembly is a key boost to engine power output. It accurately controls the fuel injection amount and injection direction, allowing fuel to burn fully and efficiently in the combustion chamber. Reasonable design and stable performance can effectively improve the fuel utilization rate of the engine and enhance equipment power. It is widely used in engines of various power machinery.
Product Introduction
The High-Pressure Common Rail (HPCR) Injector Set is a critical component in modern diesel fuel systems, designed to deliver precise fuel injection at ultra-high pressures (up to 2,500 bar or higher). Engineered for maximum efficiency and performance, our injector set ensures optimal combustion, reduced emissions, and improved fuel economy. Compatible with leading OEM systems (Bosch, Delphi, Denso, Siemens), this set is ideal for engines requiring high precision, durability, and reliability under extreme operating conditions.
Key Advantages
Ultra-High Pressure Performance – Supports pressures up to 2,500+ bar for superior atomization and combustion efficiency.
Precision Fuel Control – Electronically controlled for accurate dosing and timing, enhancing power and responsiveness.
Enhanced Durability – Constructed with hardened steel and advanced coatings to resist wear and corrosion.
Lower Emissions – Helps meet Euro 6, Tier 4, and EPA standards by minimizing particulate and NOx emissions.
Improved Fuel Economy – Optimized spray patterns reduce fuel waste, cutting operational costs.
Plug-and-Play Compatibility – Direct replacement for OEM injectors, ensuring seamless integration.
