Performance Diesel Injectors 116-8866

A: Yes. Although natural gas is cleaner than diesel, it may carry trace amounts of oil, particles, or hydrogen sulfide from the pipeline. Recommendations: 1. Replace the gas filter regularly (usually every 10,000-20,000 km or as per the manual). 2. Every 40,000-60,000 km, check the flow consistency of the injection valves. If necessary, perform a non-disassembly cleaning with a specialized cleaner or ultrasonic cleaning on professional equipment to remove any contaminants that may have accumulated in the valve orifices.

A: Extremely dangerous. Natural gas is a flammable and explosive gas. A leaking injection valve (especially an internal leak when the engine is off) can cause gas to enter the intake manifold, potentially leading to: 1. Detonation during startup: When the starter motor turns the engine, the accumulated air-fuel mixture in the cylinder may burn violently, damaging the starter motor or flywheel. 2. Spontaneous entry into the cylinder: This can cause the engine to continue running after the ignition switch is turned off ("running"). If any signs of a leak are detected (such as a gas smell), the gas cylinder valve must be closed immediately, and the engine stopped for inspection.

A: Professional testing requires a fuel injector flow test bench to measure the flow curves and sealing performance at different duty cycles. Preliminary checks can be performed on the vehicle: 1. Use a diagnostic tool to read fuel system fault codes and long-term fuel trim values. 2. With the engine running, use a stethoscope or long-handled screwdriver to listen for clear and even "clicking" sounds from each injection valve. 3. Measure the resistance of each injector coil to ensure it is consistent and within the standard range.
