Abstract
PURPOSE:To improve the combustibility of an engine by forming the inside borderline of the squish area of a four(4) valve engine with a near square which is formed by the outside common lines tangent to respective circles circumscribing two(2) valves adjacent to each other in the peripheral direction of the cylinder and whose corner sections form circular arcs. CONSTITUTION:Each cylinder 1 of a four(4) valve engine is provided with two(2) suction ports and exhaust ports 4, 5; 13, 14 respectively and formed with a squish area between a cylinder head 28 having a bent-roof shape lower face and ringed plane section 32 of the top of the piston 7. The outside borderline of the squish area 33 is formed with the circumference of the cylinder. In this case, the inside borderline of the squish area 33 is formed with a near square formed by the outside common lines tangent to respective circles circumscribing two(2) valves adjacent to each other in the peripheral direction and circular arcs forming a part of the outer periphery of each valve and blistering in the outward and radial direction and having circular arcs.
