Gas fuel

Abstract

The invention relates to a gas fuel, mixed of two or more combustible gases, mixing hydrogen gas with natural gas to compose a gas fuel-1, and mixing water gas with natural gas to compose a gas fuel-2, and the best molar content of hydrogen gas of the gas fuel-1 in the mixed gas is 30%-45% and that of water gas of the gas fuel-2 in the mixed gas is 30%-50%. Its beneficial effects: because the above gas fuels both contains hydrogen gas and natural gas, as compared with single natural gas fuel, the flame spreading speed is high, thus increasing the heat-power conversion and beneficial to reduce the discharge of unburned hydrocarbons. As compared with single-hydrogen gas or water gas fuel, the quench-extinguishing layer has a proper thickness and can avoid the flareback phenomenon, and simultaneously it has lower cost, completely suitable to act as a clean substitutive fuel for internal-combustion engines.

Description

technical field [0001] The invention belongs to the substitute fuel technology for internal combustion engines, and in particular relates to a novel gas fuel. Background technique [0002] With the increasing shortage of petroleum resources and the strengthening of people's awareness of atmospheric environmental protection, finding clean alternative fuels for internal combustion engines has become one of the important topics in the research of internal combustion engine technology. Natural gas is a very promising alternative fuel for internal combustion engines. Its main component is methane, and its storage capacity is very abundant. Methane can be used as a single fuel in a spark-ignition internal combustion engine (gasoline engine), and can also be used in a diesel engine in a dual-fuel way that is ignited by diesel. The problems of using natural gas as fuel for internal combustion engines are: compared with gasoline or diesel fuel, the flame p...

AI Technical Summary

Problems solved by technology

The problems of using natural gas as fuel for internal combustion engines are: compared with gasoline or diesel fuel, the flame propagation velocity of natural gas mixture is low, the thickness of the quenching layer is thick, and the quenching length is broken. high fuel consumption rate

Hydrogen is another gas substitute fuel for internal combustion engines. It has the advantages of fast flame propagation speed, thin quenching layer thickness, and large quenching length. However, there are two problems with pure hydrogen as an internal combustion engine fuel. The phenomenon of tempering of the intake pipe often occurs in the process, causing the intake pipe to be fired; secondly, the cost of hydrogen is very high, and it is uneconomical to use alone as an internal combustion engine fuel

[0003] So far, the natural gas or hydrogen alternative fuels used in internal combustion engines for vehicles are all in the form of a single component, so the above shortcomings cannot be avoided
