The combustion characteristics of spark assistant compression ignition mode under different loads and fuels were explored. as well as by constructing artificial neural networks(ANN) model. the prediction ability of different algorithms for engine performance was discussed. Burning methanol and n-butanol can help to improve IMEP and induce earlier spontaneous combustion. https://www.jmannino.com/amazing-price-Handlebar-for-Motovox-MBX10-and-MBX11-Mini-Bikes-amazing-deal/
