Abstract
PURPOSE: To enable the HC concentration and NOx concentration in an exhaust gas to be both reduced only by the exhaust gas recycling, by means of taking out the exhaust gas of a high HC concentration from near the inner circumferent wall of the exhaust port, and of sending to the combustion chamber by allowing this to be recycled into the gas absorbing system.
CONSTITUTION: For example, an exhaust gas feeding port 14 is connected to a gas absorbing path 8 of a little upstream side of a full closing position of a throttle valve 9 via an exhaust gas recycling controller 13, by means of setting up an exhaust gas recycling path 12 having an exhaust gas taking out port 11 of a pipe-shape adjacent to the inner wall of an exhaust port 5. Unburned components HC are discharged from the quench layer in the combustion chamber 2, and flows along the inner circumferent wall in the exhaust port 5. Here, the unburned component HC is absorbed by the exhaust gas recycling path 12 from the exhaust gas taking out port 11, and the adequate quantity of the exhausted quantity is supplied to the gas absorbing path 8 from the exhaust gas feeding port 14, thereby is allowed to be reburned by sending to the combustion chamber 2.
