The CAT HEUI Injector 557-7627 is made for C7-series engines using the HEUI fuel system. It uses high-pressure oil down to its internal chamber, actuated by oil pressure, while the ECU controls the timing and injection duration. This delivers very precise fuel pulses for efficient combustion and good throttle response. The injector body is built for durability under vibration and thermal load, making it ideal for loaders, graders, or excavators powered by C7.
