FAQ
Q:How to identify abnormal power and fuel consumption
A: Engine power is significantly reduced (e.g., excavators are powerless to operate, heavy trucks accelerate slowly), while fuel consumption increases significantly (fuel consumption is more than 10% higher than normal operating conditions).
Q:How to detect fuel injection flow rate
A:Simulate operating conditions on the test bench and measure the fuel injection flow rate per unit time. If the flow rate deviates from the standard value by more than 5%, it indicates that the injector atomization or the nozzle is worn.
Q:Do you have your own factory or partners?
A:We operate our own factory in China and partner with top-tier suppliers for stable supply chains.
Q:What shipping options are available?
A:Express (DHL/UPS/Fedex), sea freight, air freight
Q:Are products tested before shipment?
A:All products undergo 100% functionality testing before shipment to ensure they are fully functional.
Small Tips
fuel injector professional testing methods
Fuel injection pressure test
Use an injector tester to check if the injection pressure is within the manufacturer's specified range (e.g., 1600–1800 bar for C7/C9 injectors). If the pressure deviation exceeds 10%, the injector needs to be replaced.
01
Fuel injection flow detection
Simulate operating conditions on the test bench and measure the fuel injection flow rate per unit time. If the flow rate deviates from the standard value by more than 5%, it indicates that the injector atomization or the nozzle is worn.
02
Engine fault code reading
By reading ECU fault codes using a Caterpillar diagnostic tool, if codes such as "injector performance failure" or "abnormal injection pressure" appear, the specific injector problem can be located by combining the fault code number.
03
High load conditions
If excavators or heavy trucks operate at full load for extended periods, it is recommended to disassemble and inspect the injector every 500–800 hours. If severe carbon buildup in the nozzle orifice or wear on the needle valve is found, replace it promptly.
