Cummins injector 4307428

Cummins injector 4307428 is a high-performance diesel engine injector produced by Cummins, which is commonly used in its diesel engine series, especially in commercial vehicles, construction machinery and generator sets. The injector is a key component in the engine fuel system, responsible for injecting fuel into the cylinder in a precise spray form to ensure the efficiency of the combustion process and the performance of the engine.

Cummins injector 4307428 performance introduction
Basic overview
Model: 4307428

Applicable engines: Applicable to a variety of Cummins diesel engines, such as NTA885, QSB, ISB, etc.

Type: electronically controlled injector

Injection method: high-pressure injection

Fuel type: diesel

Applicable engine displacement: Applicable to medium to large diesel engines

Performance characteristics
Precise injection control:

The 4307428 injector adopts an advanced electronic control system, which can accurately adjust the injection timing, injection amount and injection pressure. Precise injection control ensures that the engine can achieve optimal combustion efficiency under various operating conditions.

Improve fuel efficiency:

Through the precise injection system, it can ensure complete combustion of fuel, reduce unburned fuel emissions, and improve fuel efficiency. This can not only effectively reduce fuel consumption, but also improve the overall performance of the engine.

Reduce emissions:

The precise spray effect of the injector helps reduce the emission of harmful substances, such as nitrogen oxides (NOx) and particulate matter (PM). This is essential for meeting modern environmental regulations, especially under the requirements of Euro III and Euro IV emission standards.

High-pressure injection:

The 4307428 injector can provide high-pressure injection, usually with an operating pressure of between 1500 and 2000 bar. High-pressure injection can atomize diesel more finely and improve the uniformity of the mixture, thereby enhancing combustion efficiency and power output.

Improve power and response speed:

Due to the precise control of injection quantity and injection timing, the injector can improve the engine’s response speed and power output, especially under heavy load conditions, which can significantly improve the engine’s starting performance and acceleration performance.

Reliability and durability:

Cummins injectors use high-quality materials and precision processing technology to ensure their long-term efficient and stable working performance. Its high temperature and high pressure resistance make it suitable for various extreme working conditions, such as high load and high temperature environment.

Easy to maintain:

The injector design makes it easier to inspect and maintain. Regular inspection and cleaning of the injector can effectively extend the service life of the engine and reduce maintenance costs.

Working principle
The injector receives signals through the electronic control unit (ECU) and adjusts the injection amount, injection timing and injection pressure in real time according to the engine’s working conditions (such as speed, load, temperature, etc.). When the diesel injector sprays high-pressure atomized fuel, the fuel is fully mixed with air and enters the cylinder for efficient combustion to generate power.

Scope of application
Commercial vehicles: such as trucks, buses, trucks, etc.

Construction machinery: such as excavators, bulldozers, cranes, etc.

Agricultural machinery: such as tractors, harvesters, etc.

Generators: diesel engines used for generators
