Description
This fuel injector with part number 2645A753 / 321-3600 is a core fuel injection spare part designed for C6.6 construction machinery diesel engines applied on excavators. It features a segmented precision forged steel housing with built-in electronic control solenoid valve and high-pressure nozzle assembly, as well as a side-mounted high-pressure oil inlet. Controlled by electronic signals to open and cut off fuel supply precisely, it perfectly matches the original fuel supply system of excavator engines for direct OEM replacement, suitable for all excavator models equipped with C6.6 power unit.
Advantage
Strictly follows original dimensional standard on overall outline, nozzle length, thread size and electric connector, plug-and-play without extra modification for easy installation and replacement;
High-strength alloy steel as main raw material, quenched valve parts for outstanding wear resistance against high-pressure fuel erosion and diesel impurity abrasion to avoid fuel leakage;
All injectors finish bench calibration before delivery with unified injection pressure and fuel delivery volume, offering excellent interchangeability;
Optimized for heavy-load, frequent start-stop, high/low temperature outdoor working conditions of excavators and compatible with original factory fuel supply pressure specification.
Performance
Excellent fuel atomization: Precisely machined tiny nozzle holes produce fine atomized fuel under high pressure for complete combustion inside cylinder, cutting down black smoke emission and fuel consumption effectively;
Fast electronic response: Quick solenoid valve switching ensures accurate fuel injection timing during idle, acceleration and heavy load, delivering smooth engine power output without stuttering;
Stable high-pressure tightness: Premium sealing structure resists deformation under long-term high pressure operation to prevent oil seepage or dripping and related power loss or cylinder misfire;
Reliable cold start performance: Stable injection consistency under low ambient temperature enables smooth cold startup and reduces idle shaking troubles.
