Abstract
PURPOSE: To provide at the same time decrease an appropriate angle of valve and form of combustion chamber, and the number of parts, by reducing the interval between cam shafts.
CONSTITUTION: Bearings for cam shafts 20, 40 are provided berween cams 22 and 24 as well as cams 42 and 44 on each cam shaft 20, 40 of a four-valve and two- overhead cam shaft type internal combustion engine, which is directly operated by cams 22, 24, 42, 44 with two each air intake, exhaust valves 16, 18 for each cylinder installed on said two cam shafts 20, 40.
