Abstract

The invention discloses an LNG-CNG dual fuel power gas supply system. The LNG-CNG dual fuel power gas supply system comprises an LNG fuel power gas supply system, a CNG fuel power gas supply system, an integrated device and a control device. The integrated device is arranged among the LNG fuel power gas supply system, the CNG fuel power gas supply system and an engine. Through the integrated device, the LNG fuel power gas supply system and the CNG fuel power gas supply system can both be communicated with the engine. The control device controls one of the LNG fuel power gas supply system and the CNG fuel power gas supply system to supply gas to the integrated device. The LNG-CNG dual fuel power gas supply system has the beneficial effects of being high in cruising power, capable of being filled with gas conveniently, easy to operate, high in work efficiency, high in economical efficiency, high in safety and small in occupied space.

Description

Technical field [0001] The invention relates to the field of automobiles, in particular to an LNG-CNG dual-fuel power gas supply system and natural gas vehicles. Background technique [0002] The methane content of natural gas is more than 90%, which is a good fuel for automobile engines. Natural gas vehicles are vehicles that use natural gas as fuel to power their engines. Natural gas vehicles are mainly divided into LNG vehicles (liquefied natural gas vehicles) and CNG vehicles (compressed natural gas vehicles) according to the different fuel supply systems of natural gas vehicles. The fuel supply system for natural gas vehicles on the market is mostly a single LNG gas supply system or CNG gas supply system. The LNG gas supply system is characterized by strong endurance. However, because there are currently fewer LNG refueling stations, LNG vehicles exist It is difficult to inflate, and it is easy to cause the problem of no fuel in the driving process, which will cause the ca...
