Abstract

The invention relates to a method and power system for driving an automobile through high-pressure hydrogen mixed fuel. The power system comprises a hydrogen mixed fuel storage tank, a piston type gas engine, a turbocharging unit, a heat exchanger, a heat storage device, a cold storage device and an air pipeline. High-pressure mixed fuel gas in the hydrogen mixed fuel storage tank is subjected to dehydration and heat exchange and arrives at the piston type gas engine after releasing pressure energy through the turbocharging unit and the cold storage device releases the refrigerating capacity or after releasing pressure energy through a pressure energy utilization and control unit, air arrives at the piston type gas engine after being compressed through the turbocharging unit, and the piston type gas engine conducts combustion and does work so as to drive the automobile to run. Waste gas is discharged by releasing the pressure energy through the turbocharging unit, or is discharged after exchanging heat with the hydrogen mixed fuel gas. According to the method and the power system, the turbocharging unit is driven by the pressure energy of the high-pressure mixed fuel gas to compress the air, the refrigerating capacity generated after the high-pressure mixed fuel gas expands and cools is recycled, the pressure energy of the high-pressure hydrogen mixed fuel is sufficiently used, and the thermal efficiency of an automobile power system is improved.

Description

technical field [0001] The invention belongs to the technical field of power machinery equipment, and relates to a method and a power system for driving an automobile by using high-pressure hydrogen mixed fuel. Background technique [0002] In the 21st century, the automobile engine industry has developed rapidly, but gasoline engines and diesel engines are still the main types of automobile engines. Gasoline and diesel are non-renewable resources. In order to alleviate a series of negative effects brought about by the shortage of petroleum resources and reduce air pollution and vehicle engine exhaust emissions, it is necessary to find alternative fuels for engines, and hydrogen energy is currently the most ideal clean fuel. . Hydrogen energy is a renewable resource among many alternative energy sources. It has a high calorific value and most of the products after combustion are water vapor. It is an ideal green fuel. Hydrogen energy as an alternative fuel can solve two ma...
