Abstract

PURPOSE: To omit complicated pipings, by emloying an arrangement in which secondary air to be supplied to the exhaust system for purifying exhaust gas is supplied from an air passage formed in the cylinder.
CONSTITUTION: In cylinder head 12, there are formed an exhaust port 16 and an intake port 17. Inside the cylinder 11 formed with combustion chamber 14, a secondary-air introducing passage 23 is formed around combusion chamber 14, and the passage 23 is communicated to exhaust port 16 via connecting port 21a. Since, in accordance with the above arrangement, passage 23 is not exposed to the outside, its layout can be simplified.
