In the power system of the Carter engine, precise fuel injection is the core of efficient operation. The 319-0678 fuel launch pump is like a "power thruster", injecting strong kinetic energy into the engine with excellent performance.
The pump is equipped with precision machined plunger components, combined with CNC grinding technology. The clearance between the plunger and the sleeve is controlled at 0.001-0.003 millimeters, ensuring no fuel leakage under high pressure and stable injection pressure at 1800-2000 bar, providing sufficient power for fuel atomization. The unique spiral groove design can automatically adjust the fuel supply according to the engine speed, accurately control the fuel at idle, increase the supply at high speed, and achieve efficient combustion under all operating conditions. Compared with traditional pump bodies, the fuel utilization rate is increased by 15%.
The pump body is made of high-strength alloy cast iron, which has undergone aging treatment to eliminate internal stress. Its impact resistance and wear resistance have been significantly improved, and it can withstand the vibration and high temperature of the engine during long-term operation. The internal bearings are made of high-temperature resistant ceramic materials, combined with long-lasting lubricating grease, which extends the service life to twice that of ordinary bearings. Standardized installation interface and positioning pin design ensure perfect integration with the Caterpillar engine, without the need for additional processing during installation, greatly reducing assembly errors.
For complex working conditions, the pump is equipped with an overload protection mechanism. When there are too many fuel impurities or abnormal pressure, the output power is automatically reduced to avoid damage to core components. Before leaving the factory, each 319-0678 fuel launch pump must undergo 200 hours of continuous operation testing and 1000 pressure shock tests to ensure stable operation in an environment ranging from -25 ℃ to 120 ℃. Choosing it can maintain strong engine power, reduce fuel consumption and emissions, and provide reliable power support for various heavy equipment.
