What to Do When an LNG Vehicle is Parked for a Long Time?

[JoelLynn]

LNG vehicles parked for an extended period must be kept away from controlled areas such as workshops, warehouses, oil depots, and other places with fire hazards or flammable and explosive materials. Here are the relevant details: 1. LNG: LNG stands for liquefied natural gas at normal pressure and low temperature, with a storage temperature of -162 degrees Celsius. When heat penetrates the storage tank, some of the liquid LNG absorbs the heat, evaporates, and turns into gaseous natural gas, causing the tank pressure to rise. If the pressure exceeds the rated level, the pressure relief valve will open to release the gaseous natural gas. 2. Precautions: Driving such vehicles requires a specialized license, and drivers must adhere to speed limits to prevent hazards.

As a veteran driver with over a decade of experience operating LNG trucks, I understand the importance of system maintenance and safety during prolonged parking. First, shut off all gas valves and electrical switches, preferably draining any residual LNG gas to prevent leakage risks. Then disconnect the battery negative terminal to avoid power drain. Park in a cool, well-ventilated area like a garage or parking lot corner, avoiding direct sunlight or covering with dust-proof sheets. Check battery voltage and tire pressure every two months to ensure no deformation or air leakage. Before restarting the vehicle, have a professional technician conduct a thorough inspection, especially checking gas pipeline seals—safety comes first. Though these steps may seem tedious, they extend vehicle lifespan and prevent accidents.

I prioritize safety and environmental protection, always considering risk control when parking LNG vehicles. Natural gas is prone to volatilization, so before long-term parking, ensure the entire system is tightly sealed to avoid any leakage risks. Park in an open space with good ventilation and away from fire sources. It's best to disconnect the battery or charge it periodically to prevent aging. Occasionally check the tank and pipelines for any abnormalities, such as odors or discoloration, to avoid environmental pollution or fire hazards. Conduct a simple test drive and safety check before starting the vehicle—it saves money and provides peace of mind.

When I first bought my LNG sedan, I didn't know the parking techniques, but later I learned a simple method. Before parking, turn off the engine and all power switches, including the air conditioning. Find a flat and stable spot, such as a corner in the garage, to park. Check the battery every one or two months to see if it still has power, using a voltmeter or observing the dashboard. Before driving, make a quick trip to the repair shop for a safety check, and you're all set—easy and hassle-free.
