Liquid Natural Gas Challenges Automotive New Energy

According to the latest news, the LNG heavy truck (liquid natural gas) project has been put into production, and the LNG passenger car project has also been formally reported. In the future, not only taxis but even ordinary family cars will also be affected. For new energy sources that are just beginning to develop, LNG will pose new challenges just as traditional energy sources “blossom trees”.

Those who drive should know that diesel is more efficient than gasoline under the same volume, but now this situation is changing. According to the information of the China Automobile Association, after many years of research, domestic LNG heavy trucks have begun to be put into production, and the LNG engine miniaturization project has also officially started, which indicates that there is a strong one in the domestic automobile energy family. Contenders.

In the interview, the reporter learned that the reason why natural gas was selected as an important transportation energy was mainly because of its more diversified application. Huang Chong, a researcher at Monita (China), told reporters that natural gas has a calorific value 1.2 times that of diesel. However, under the same weight, the price is even less than 50% of that of diesel. The long-term use cost savings are very obvious. From the perspective of post-combustion products, natural gas is also a clean energy source, which is in full compliance with domestic requirements for clean energy.

Dong Yang, executive vice president of China Automotive Industry Association, also said in an interview that LNG heavy trucks are currently being put into production at a number of domestic large-scale automobile enterprises, and will be officially open production in the first half of next year. The miniaturization project has also been officially reported upwards. It is expected that the project will be officially approved in the second half of next year and will be put into production in 2014. "Technically, it's not complicated. The internals of the engine haven't changed much. It's just that the energy reserves are different." He told reporters that traditional natural gas vehicles store energy in a gaseous manner and must therefore be A “big bag” is installed in the trunk of the car, which is then converted into a liquid for use by the engine through a conversion device. In the LNG project, natural gas was stored in liquid form at the beginning and then directly supplied to the engine. This significantly improved the efficiency and reduced the volume by 80% compared with the original.
