612600081583 Fuel Metering Valve

The 612600081583 is a fuel metering valve made for diesel engines. It fits Weichai WP10/WP12 series engines, and works with heavy-duty vehicles like Shaanxi Auto Delong and Sinotruk HOWO—also some engineering machines such as loaders and excavators.Its job is to control how much fuel gets injected, based on how the engine’s running. And it fits right into the original engine space of compatible machines: just take out the old valve and put this one in, no extra fixes needed.

Features And Advantages ：

① Precise fuel control: Adopts 10-nozzle structure and PWM pulse control , adjusts fuel flow by changing valve core position, ensuring 3% metering accuracy-optimizes fuel combustion, reduces fuel consumption by 5%-8% under heavy load .

② Durable structure: Valve core is wear-resistant, housing is corrosion-resistant alloy; resists high-temperature oil erosion (up to 120℃) and engine vibration , passed 500-hour continuous operation test, service life 2x longer than ordinary metering valves .

③ Fast replacement: Matches original mounting holes and electrical connectors of Weichai engine high-pressure oil pumps , aligns perfectly with ECU signal protocols, installation takes only 30-60 minutes, saves repair time .

④ Stable operation: Coil resistance stays within 2.6-3.15Ω (20℃) , no circuit short/open circuit faults; works with rail pressure sensor to form closed-loop control, avoiding abnormal pressure and engine limp mode .

Application Scope ：

Only for heavy-duty trucks with matching Weichai engines (common: HOWO/SHACMAN) and Bosch high-pressure oil pump systems .

FAQ ：

Q1: Does it fit light trucks or gasoline cars?

A1: No, only diesel machines with matching models-light trucks and gasoline cars won't work.

Q2: After installation, the engine power is low-why?

A2: First check if the valve is installed tightly (no fuel leaks). If it is, check if the fuel pipeline is blocked or the wiring is loose.

Q3: How often to maintain it?

A3: Check if the fuel pipeline connections are tight every 15,000 km, and wipe the valve body clean every 3 months. Good maintenance makes it last longer.

Q4: Do I need special tools to install it?

A4: No special tools-just a regular wrench set. It's better to have experienced mechanics do the install, and it takes about 30-45 minutes.
