What is the optimal pressure for LNG vehicle cylinders to save gas?

[LaHenry]

During normal vehicle operation, the pressure in the cylinder should ideally be maintained between 0.8~1.2MPa. If the vehicle experiences power loss or the cylinder pressure is too low (below 0.8MPa) during operation, here are the possible reasons for low LNG pressure: 1. Just refueled with low-temperature liquid; 2. The pressure regulator valve is set too low; 3. The economizer valve pressure setting is too low; 4. The safety valve is damaged, causing gas leakage; 5. Other pipelines have gas leakage issues. Solutions: 1. If the cylinder pressure is below 0.8MPa, use soapy water to check for gas leaks at pipe joints. If leaks are found, first fix the leaking areas, then activate the pressurization system to increase pressure; 2. If the cylinder pressure is low and the safety valve is leaking, pour hot water over the safety valve and gently tap it with a tool until the leak stops. If the issue persists, replace the safety valve.
