Guide surface scuffing: when fuel contains hard particles (such as SiO₂ and rust), it will lead to needle valve movement jamming and unstable opening pressure.
Industry Alert: Guide Surface Scuffing – A Hidden Threat to Common Rail Injector Operation Caused by Hard Particles Date: March 31, 2026 Source: Global Diesel Injection Maintenance Journal In the high-pressure common rail fuel injection system, the guide surface of the needle valve serves as the ...
Radial clearance deviation: the normal range is 1～3μm, and it exceeds 5μm after wear, leading to direct leakage of high-pressure oil, failure to build rail pressure, and a sharp surge in return oil.
