Diesel engine injection nozzle
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.
Piston oil pump CB-18
The fuel injection pump assembly is crucial in the engine oil supply process. It can achieve an injection accuracy of ±0.5mg per cycle, and inject oil at a pressure of up to 180MPa, allowing the fuel to be fully atomized and efficiently mixed with the air. Effectively enhance engine power output by about 8%, reduce exhaust emissions, and is suitable for all types of diesel power machinery.
Fuel pump assembly
The fuel injection pump assembly is the fuel control hub of the engine. Fuel can be injected as needed at a pressure of about 150MPa, and the injection interval error is controlled within ±0.1ms. Optimize the combustion process, increase engine power by about 10%, reduce fuel consumption, and are widely used in construction machinery, generator sets and other equipment.
Multi-cylinder pump assembly
The injection pressure can reach 140MPa, the injection operation can be completed in milliseconds, and the injection angle deviation is controlled at ±2°. Optimize engine working conditions and increase power by about 7 - 10%. It is suitable for trucks, ship main engines, etc. to ensure strong and stable power.

1st Injector body machining line established in Changzhou Huahui

2025-09-16

In September 2025, Changzhou Huahui Fuel injection Co.Ltd officially established a production line for rough and fine processing of fuel injector bodies, with a monthly capacity of 100,000 pieces. This production line has introduced two advanced KADIA honing machines. Only a few factories in China own this high-precision equipment. Currently, our company has the ability to supply both OEM and the aftermarket. We welcome inquiries and communication from all customers and friends.
