Description

一种具有汽油气化装置的内燃机 技术领域
本发明涉及一种具有燃油气化装置的汽油内燃机。
背景技术
目前汽油内燃机的工作原理是电控喷油嘴直接将汽油喷射到内燃机的气缸中，然后点火爆燃做功的，由于汽油燃烧不充分等其他因素，内燃机热效率通常只能达到燃料化学能的1/3左右。从电喷嘴喷出的汽油是小颗粒浮悬物，而颗粒状的汽油无法与氧气充分接触，所以在气缸点火爆燃过程中有相当汽油分子未经充分氧化，而没经氧化的汽油分子成为废气排出内燃机，浪费能源的同时污染了环境。调查表明，汽车尾气已成为今日城市空气污染物PM2.5的重要来源。汽车尾气中主要污染成分是碳氢化合物，一氧化碳及氮氧化物，其中碳氢化合物与一氧化碳是由于发动机汽油燃烧不充分直接所至，因此亟待对现有的汽油内燃机的燃料与空气混合方式进行改进，以提高汽油燃烧效率降低污染排放。
发明内容
本发明的目的是解决现有技术中汽油内燃机汽油进气缸后点火过程中燃烧不充分问题，提供一种具有燃油气化装置的汽油内燃机。本发明设计一种具有燃油气化装置的汽油内燃机，包括汽油内燃机，其特征在于：在汽油内燃机电控喷油嘴一端连接有汽油气化装置，汽油气化装置另一端直通汽油内燃机的进气门，所述的汽油气化装置内有一高温恒温腔体，腔体的一端为连通电控喷油嘴的汽油入口，腔体的另一端连通汽油内燃机的进气门。汽油气化装置内的高温恒温腔体内安装有高温加热元件，所述的高温加热元件为恒温电发热元件。本发明的优点是气态汽油是汽油分子团的最小形式，由此能做到汽油分子与氧气接触的最大化，此时在气缸进气充足条件下，发动机缸内汽油的燃烧可以达到最大化，从而排出的废气可以达到最小排放。
附图说明
附图1为本发明的结构整体示意图，图2为本发明的油气化装置结构示意图。
具体实施方式
图中一种具有燃油气化装置的汽油内燃机，包括汽油内燃机1，其特征在于：在汽油内燃机的电控喷油嘴2一端连接有汽油气化装置3，汽油气化装置另一端直通汽油内燃机的进气门5，所述的汽油气化装置内有一高温恒温腔体4，腔体的一端为连通电控喷油嘴的汽油入口，腔体的另一端连通汽油内燃机的进气门。汽油气化装置内的高温恒温腔体内安装有 高温加热元件6，所述的高温加热元件为恒温电发热元件(恒温电发热元件安装位置内外不限)。图中7为油管。
本发明的优点是提高汽油碳氢化合物的氧化反应率着手。本发明所涉及的汽油内燃机的燃料供给方式有别其他，汽油先由电控喷油嘴控制油量，然后汽油进入气化装置的腔体内加热气化，气态汽油与空气混合后共同进入内燃机气缸8，此时气缸内的燃空比约为1：14，随后压缩点火爆炸(氧化反应)，其化学反应方程为：2C8H18+25O2---------16Co2+18H2O
本发明的气化装置的高温恒温腔体内的温度是恒定的(可设定为280°)，气化后的汽油与空气混合一起进入气缸，接下去是发动机的压缩，点火与排气冲程，完成发动机的四冲程工作。由于气态汽油是汽油分子团的最小形式，所以能达到汽油分子与空气充分接触，此时在其他相同的条件，发动机缸内汽油的燃烧可以达到最大化，即最充分燃烧与最小污染排放。
