Abstract

In order to improve energy efficiency and protect the environment, new energy vehicles have been developing vigorously. As one kind of the vehicles, CNG (Compressed Natural Gas) Automobiles and CNG & Electric hybrid cars have been accelerating promotion. However, the current CNG vehicles are reducing the pressure of CNG through a reducing valve, so that achieves the intake gas pressure to the engines. Undoubtedly, it is a waste of the pressure energy for CNG. For utilizing of the pressure energy, this paper promotes a method that applies regenerative multi stage valve piston expanders to recycle the high pressure CNG energy power translated into electricity. It is estimated that the efficiency of the expander system under this technology is more than 55%, the power storage and utilization efficiency is more than 90%, and the overall CNG pressure energy recycling efficiency can reach more than 50%.
