Abstract: The present invention relates to a fuel/air supply and ignition apparatus for stable ignition and combustion of an exhaust gas purifying filter for diesel automobiles. In detail, a disturbance device, formed in a cone shape, is installed at the end of an injection tube. A mixer of exhaust gas passing through an exhaust pipe and fuel/air supplied by the injection tube forms a wide recirculation area on the back of the disturbance device. Thereby, enough combustion time is obtained. The enough combustion time reduces the exhaust of the fuel which is not combusted and enables the stable supply of gas with high temperatures to DOC and DPF by stabilizing flames.
