Function
1. Precise Air-Gas Mixing: The diaphragm moves up and down driven by the negative pressure (vacuum) generated in the engine's intake manifold. When the negative pressure is low, less natural gas enters, preventing an overly rich mixture. When the negative pressure is high, more natural gas is allowed into the airflow, achieving dynamic air-fuel ratio adjustment to ensure a uniform and combustible mixture, improving combustion efficiency.
2. Real-Time Adjustment in Response to Engine Operating Conditions: Working in conjunction with the ECU, EPR, throttle body, and intake pressure sensor, a closed-loop control system is formed. At low speeds/idle, a small amount of natural gas ensures stable combustion. At full load, a large flow of natural gas provides strong power and rapid response, avoiding lag or sudden changes that could cause vibration/misfire.

For natural gas vehicles, it is recommended to check the gas system every 30,000–50,000 kilometers or every six months, including visually inspecting the diaphragm (if possible), reading the OBD code, and checking for leaks. Special attention should be paid to the inspection before winter or after the hot season (as drastic temperature changes accelerate aging).
