Title: Study of autoignition in a premixed charge, internal combustion engine using comprehensive chemical kinetics: experiments and predictions

Abstract

A model is developed to predict autoignition in a premixed charge engine. Experimental data are obtained with spark ignition and premixed charge compression ignition. Seven fuels are examined: methane, ethane, propane, n-butane, methanol, ethylene, and propylene. Binary fuel mixtures are also examined, as are the effects of engine speed, equivalence ratio, load, and compression ratio. An initial temperature correction must be used to accurately predict the observed time of autoignition. Analysis of spark-ignited data show that the fuels fall into two groups, depending on the temperature correction ranging from 35 K to 80 K: methane, propane, n-butane, and methanol. Three fuels fall into the group with a temperature correction ranging from 110K and 140K: ethane, ethylene, and propylene. The rate of pressure rise during compression ignition is controlled by varying the fuel-air equivalence ratio. The effects of compression ratio and load on the rate and load on the rate of pressure rise are also examined. The predicted rates of temperature rise during compression ignition are compared to the observed rates of temperature rise.
