柴油机采用乳化油可以节油。所谓乳化油,就是让油和水按一定的比例混合,经搅拌或振荡,使水以直径为0.5～5μm的微粒均匀地分散于油中,微细水滴被油膜包围而形成油包水型的液珠,颜色呈乳白色。乳化油根据其稳定性分为稳定乳化油和不稳定乳化油。稳定乳化油稳定时间长,油水不会分层,但需加入价格昂贵的乳化剂,成本高,不易推广;不稳定乳化油指稳定时间短,但足以保证从乳化器出来后能稳定地进入气缸燃烧,故乳化油必须是边乳化边燃烧的。
Diesel oil can be used to save oil. The so-called emulsified oil, is to make a certain percentage of oil and water mixing, stirring or shaking, so that water with a diameter of 0.5 ~ 5μm particles evenly dispersed in the oil, the micro-droplets are surrounded by the film to form a water-in-oil liquid Beads, the color is milky white. Emulsified oil according to its stability is divided into stable emulsified oil and unstable emulsified oil. Stabilized emulsified oil stable time, oil and water will not stratification, but the need to join the expensive emulsifier, high cost, not easy to promote; unstable emulsified oil refers to the short stabilization time, but sufficient to ensure stable access to the cylinder from the emulsifier Combustion, so the emulsified oil must be emulsified side of the combustion.
