Experimental Study on the Autoignition Characteristics of Water-Methanol-Diesel Mixtures

The principal application of autoignition temperature (AIT) is to define the maximum acceptable surface temperature in a particular area. AIT is an important variable used to characterize the fire and explosion hazard of liquids and must be known for safe handling, storage, and transportation. Water/methanol injection (WMI) systems reduce air inlet temps and enhance combustion efficiency on turbo diesel applications. Simple mixtures exhibiting minimum autoignition behavior has been verified to be existed. However, the minimum autoignition behavior of multi-component mixture is not discussed in literature. The simple, binary and ternary solutions of n-heptane, acetone, methanol, diesel, methanol + water, methanol + diesel, methanol + water + diesel were selected as examples to investigate the minimum autoignition behavior of flammable liquids in this study.
