Caterpillar injector 254-4339 (2544339)
Injection precision for high-power engines
The fuel injector, reference 254-4339 (2544339), is a high-precision component designed for engine injection systems Caterpillar C9. These engines, essential for public works and earthmoving, require fuel atomization with absolute precision. From the perspective of sustainable maintenance, This injector ensures perfect atomization of the diesel fuel, guaranteeing rapid acceleration and maximum protection of the engine's internal components.
Advanced thermal and hydraulic engineering
Technical transparency is our priority to ensure the operational availability of your industrial equipment.
-
High-Pressure Spraying: The nozzle features micro-orifices designed to fragment the fuel into fine particles, promoting an optimal air-fuel mixture for residue-free combustion.
-
Precision Electromagnetic Control: High-speed switching solenoid allowing precise management of injection times, thus reducing diesel consumption and combustion noise.
-
High-Resistance Components: The use of hardened steel alloys for the needle and injector body provides exceptional resistance to extreme pressures and high combustion temperatures.
-
Certified Waterproofing: Integration of high-temperature seals and gaskets to prevent any fuel leakage or engine oil dilution.
