Effects of Fuel Composition and Injection Conditions on Spray Ignition

[J0801-1]エンジン, 動力システムにおける燃焼技術(1)This study aims to explore effects of fuel property and injection conditions on ignition delay for various combustion methods using a constant-volume vessel. Ignition delays of binary-component fuels which have same ignition delay under a specified ambient condition and a specified injection condition were measured under several ambient conditions. The results show that ignition delay depends on the boiling point of high-ignitability component when the ambient pressure and temperatures are reduced and on the fuel properties when the injection conditions are changed
