Abstract
PURPOSE: To perform cooling and sound insulation, by mounting a water jacket around a path for introducing secondary air.
CONSTITUTION: A valve box 5, which upper portion is opened, is integrally molded at an approx. central location of an upper portion of a horizontal cylinder block 1, a cover 6 is covered on the valve box 5 and a secondary air suction valve 7 is encased and installed to these insides. A path 17 for introducing secondary air, which is communicated with the valve box 5 and horizontally extends toward a cylinder head 3, and similar paths 19, 20 for introducing secondary air, which are branched in a trifurcated form from the path 17, extend while suitably bending to end portions in the front and rear directions of the cylinder block 1 and open to a right end surface 18, are integrally molded at a more upper position of a water jacket 16 upper than a cylinder bore 15 in the interior of the cylinder block 1, and a water jacket 21 is formed around these valve box 5 and paths 17, 19, 20.
