Analyze whether CNG vehicles are safe
2021年4月21日 日常In the promotion of natural gas vehicles, people are worried about the safety of natural gas vehicles, especially CNG vehicles. This is a misunderstanding.
Of course, natural gas is an explosive gas, but the explosion of natural gas is conditional. After adopting a series of safety measures, after understanding its characteristics, natural gas vehicles can be used safely.
First, judging from the characteristics of the fuel itself, the ignition point of natural gas is generally above 650°C, while the ignition point of gasoline is 427°C. Natural gas is 200°C higher than gasoline, which means that natural gas is not as easy to ignite as gasoline.
Second, the volume limit of natural gas burning in air is 5% to 15%, while gasoline is 1% to 7%. In other words, a gasoline concentration of 1% in the atmosphere is more prone to fire. Natural gas is much better than gasoline because it must accumulate to 5% before reaching the lower combustion limit.
More importantly, natural gas is lighter than air, and its density is only 55% of air. If it leaks slightly, it will easily diffuse into the atmosphere without reaching the low combustion limit.
When in use, it is necessary to add odorants to the natural gas to improve the early detection ability of natural gas leakage, so as to take preventive measures.
Even if the proportion of natural gas in the air reaches the explosive limit, if there is no source of fire, there will be no explosion. Therefore, fireworks must be strictly prohibited in places where natural gas is stored.
Jiaxing Lineng Autogas Equipment Co., Ltd. reminds you that if you have modified a natural gas vehicle, you must check it on time to avoid gas leaks. If you are still hesitating whether to modify a natural gas vehicle, you can consult our related questions, and we will give you the most professional answer.
