Diesel Fuel Injector 320-0680 10R-7672 2645A747 Part Fuel Injector for C/a-t C4.4 C6.6 Engine

Wuhan Jinhong Auto Parts Co., Ltd. is a manufacturer and exporter of common rail fuel injectors integrating manufacturing,processing and R & D.

 Common rail diesel injector 320-680 adopts seven-hole precision nozzle and integrated solenoid layout, crafted from high-strength alloy for C4.4/C6.6 diesel power systems. Standard dimensional tolerance allows direct plug-and-play replacement without mechanical modification for aging original injection assemblies.
 
2.Core Features
 
Optimized inner flow channel stabilizes injection volume amid frequent pressure swings; upgraded integral sealing structure blocks diesel seepage under long-hour heavy-load running, matching common rail 1600-2200bar working pressure specs.
 
3.Performance Advantages
 
Fine mist fuel atomization promotes full combustion, cuts engine rough idle and abnormal exhaust fumes. Steady oil supply boosts low-speed torque and effectively lowers daily diesel consumption for continuous-duty industrial equipment.
 
4.Quality Highlights
 
All units complete strict flow detection, tightness and electrical resistance tests before shipment. Nitride-hardened nozzle tip resists impurity corrosion, slowing internal wear to prolong whole-unit service lifespan vs generic aftermarket alternatives.
 
5.Price & Application
 
Economical aftermarket pricing slashes maintenance expenditure vs costly original spare units. Widely used for overhaul of wheel loaders, excavators, graders and stationary generator sets with matching diesel engines.
