摘要

本實驗以柴油為主，添加其他油料或是藉由碰撞的方式產生多種不同組份的結合液滴，這些添加的油料包括甲醇、乙醇、丙醇、苯和MTBE，期待將整個柴油液滴的燃燒及微爆的研究作一個整體的呈現。

實驗中在各種不同的組份比較中發現，單獨添加在柴油裡面或是單獨與柴油液滴碰撞產生結合液滴的苯、MTBE和丙醇，對於增進燃燒速率或是促進微爆，不是沒有顯著效果就是更會有反效果，但是假如當成添加劑先行和甲醇或乙醇預混，再行和柴油液滴碰撞產生結合液滴，則會有完全不一樣的效果，反而更加增進燃燒速率和促進微爆的發生。

In this experiment, we expect to present an integral research of combustion and micro-explosion of diesel droplets. We use diesel as main liquid fuel, and produce different combined droplets by adding or impacting other other liquid fuels, that including methanol, ethanol, propanol, benzene, and MTBE.

As a result, we discover diesel droplets that combined with benzene, MTBE, and propanol, whatever added or impacted into diesel, don’t have any obvious effect in increasing burning rates or micro-explosion, even reducing burning rates or micro-explosion. On the contrast, if we use benzene, MTBE, and propanol as additives and premix them with methanol or ethanol, then impact with diesel droplets, these additives can increase burning rates and micro-explosion more easily.
