摘 要

本文就CNG—汽油两用燃料汽车作一下介绍。CNG—汽油两用燃料汽车，就是将原

来的燃料供给系统保留不变，增加一套“车用压缩天然气装置”。改装后的汽车油气两

种燃料转换非常方便，既可使用原来的汽油工作，也可使用天然气工作，但不能同时使

用。“车用压缩天然气装置”由天然气储气系统、天然气供给系统、油气燃料转换系统3

个系统组成。包括天然气储气瓶，油气燃料转换开关等关键部分。

本文更侧重结构原理及改装技术，也希望涉及这方面的车主能从中得到一点帮助。

我想当我们看到新技术在给我们带来效益的同时，希望也能提高我们的环保意识，缓解

现在所面对的能源问题。

Abstract

In this paper, the CNG - gasoline dual fuel vehicles introduce. CNG - gasoline dual fuel

vehicles, the fuel supply system of the original unchanged, added a \"compressed natural gas

for vehicle device\". The modified cars oil gas two fuel conversion is very convenient, can use

the original work of the gasoline, also can use natural gas, but not simultaneously.

\"Compressed natural gas vehicle device\" by the natural gas supply of natural gas storage

system, system, oil and gas fuel conversion system consisting of 3 systems. The key part

includes natural gas cylinder, the oil gas fuel switch etc.

This paper focuses on the structure principle and modification technology, also hope that

the owners can get a little help from. I think when we see new technology to bring us benefits

at the same time, also hope to increase our awareness of environmental protection, to ease the

energy problem now facing.

Key words：Gas vehicles, Gasoline /CNG dual fuel vehicles, Natural gas cylinder, The oil gas

fuel switch
