SHAPE OF FUEL/AIR INJECTION DEVICE FOR THE STABILITY OF IGNITION AND COMBUSTION IN A EXHAUST GAS CLEANING DEVICE OF DIESEL VEHICLE

摘要

The present invention relates to a shape of a fuel/air injecting device for the stability of ignition and combustion of an exhaust gas cleaning device of a diesel vehicle and, more specifically, to a shape of a fuel/air injecting device which has a conical disturbance device installed in an end part of a fuel/air injecting pipe which has a wide recirculation area formed on a back surface of the disturbance device by the exhaust gas passing through the exhaust gas pipe and the mixed gas of fuel and air supplied through the fuel/air injecting pipe, thereby ensuring sufficient combustion time. Therefore, the present invention can reduce the exhaust of an unburnt fuel component, stabilize flames, and uniformly supply high temperature gas to the DOC and DPF for forced combustion.
