SINOTRUK LNG High Pressure Regulator 082V08201-0305 FOR MAN MC07 ENGINE
FUNCTION
1. High-Pressure Natural Gas Pressure Reduction
Reduces high-pressure natural gas-sourced from LNG storage cylinders or post-vaporization-in a stepwise manner to the medium-to-low pressure levels required by the engine. This satisfies the fuel supply demands of high-power natural gas engines, ensuring a stable and ample gas supply across various operating conditions.
2. Stable Output Pressure and Flow Regulation
Utilizes a piston-type mechanism that achieves dynamic equilibrium among the piston, spring, valve spool, and other components to automatically adjust the output pressure in real-time, responding instantly to changes in engine load.
It maintains the stability of gas pressure and flow, preventing pressure fluctuations that could lead to engine vibration, power loss, or stalling, thereby enhancing combustion efficiency and operational smoothness.
3. Safety Protection Features
In the event of abnormal inlet pressure or downstream blockage, the unit restricts or cuts off the high-pressure gas flow to prevent damage to downstream low-pressure components. It features a built-in filter element that removes impurities, moisture, and particulate matter from the natural gas, thereby protecting the engine's fuel system.
4. Adaptability to Engine Operating Conditions
Responds rapidly to changes in engine speed and load to deliver a precisely matched volume of natural gas. It integrates seamlessly with low-pressure regulators, solenoid valves, fuel rails, and other components to form a complete natural gas fuel supply system.
Installation Location
It is connected to the LNG cylinders via high-pressure gas lines, situated either behind the cab or near the cylinder bank in the mid-to-rear section of the vehicle frame.
It is secured to a dedicated mounting bracket, ensuring a fixed position that is kept clear of high-temperature components while simultaneously facilitating the connection of coolant lines (as the pressure reducer requires heating by the engine coolant during operation to prevent freezing).

Maintenance & Replacement Recommendations
| Mileage / Time | Maintenance Content | Remarks |
|---|---|---|
| Every 50,000 km | Clean the primary pressure chamber of the high-pressure regulator; remove the inlet connector, inspect and clean/replace the built-in filter element | Perform earlier if gas quality is poor |
| Every 60,000–100,000 km | Comprehensive inspection of the regulator (sealing, pressure stability, valve core wear); inspect coolant lines and solenoid valve | Includes tightening all connectors |
| Every 2–3 years or 150,000–200,000 km | Recommended to replace the entire regulator (depending on usage intensity) | Reference for wearing parts lifespan |
| Annually or Seasonal | Before winter: check heating function; In hot seasons: check heat dissipation and sealing | Pay special attention to anti-freezing in northern regions |
