Abstract

PURPOSE:To improve perfection, stabilization an durability in the combustion by specifying the structure in the exhaust passage. CONSTITUTION:In concurrence of respectively making contiguous arrangements of exhaust ports 2,4 of first, second exhaust conduits 1, 3 and exhaust ports 5, 7 of third, fourth exhaust conduits which are unified their exhaust passages 9, 9 at the downstream with casting up together dual inner pipes 12 composed of inner, outer pipes 12',12'' with poor heat conduction made of stainless steel or the like interposed air layers 10, 11 in the exhaust passage 9, a valve guide bore 18 and an opening end 19 of the inner, outer pipes 12', 12'' are respectively tightly fixed, further dual inner pipe construction is likewise for a branch pipe part 21 and a branch pipes concentrating part 22. This facilitates high retention of temperature on the whole exhaust passage to lead from exhaust ports 2, 4, 6, 8 in a main chamber 17 to the branch pipes concentrating part 22, at the same time as mixed air thinner than theoretic air-to-fuel ratio is entirely stabilized in the main chamber 17 before buring, unburned gas is made self-combustion and purified, further inflow of casting sand between the inner, outer pipes 12', 12'', to attain the desired purpose.
