Abstract

PURPOSE: To form a passage incorporatedly within a block not to mar in appearance by concentrically boring the secondary air passage for exhaust gas purification in the block which constitutes a cylinder.
CONSTITUTION: At the top part 11 of a block at the contacting surface of a cylinder block 11 and a cylinder head 12, a secondary air feeding passage 28 is formed in the half of the range concentric with a combustion chamber 14. A suction port 17 side of the passage 28 is connected to a lead valve not indicated in the figure through an air inlet 23. Also, an exhaust port 16 side of the passage 28 is connected to the exhaust port 16 through an injection port 21.
