摘要： Multiple intake valves operatively associated in a common combustion chamber are advantageous in that the design achieves high output for an internal combustion engine. The subject modified cylinder head utilizes the advantages available in a multiple intake valve system, but further enhances the design by reducing heat rejection. In the subject modified cylinder head, three intake valves (38, 40, 42) having corresponding intake valve ports (26, 28, 30) and one exhaust valve (68) having an exhaust valve port (66) are operatively associated in a common combustion chamber. A reduction in heat rejection is achieved through a relationship between the cross-sectional areas of the intake and exhaust valve ports (26, 28, 30, 66). The intake valve ports (26, 28, 30) are constructed so that their cross-sectional area is larger than about 69 % of the combined cross-sectional area of the intake and the exhaust ports (26, 28, 30, 66).

摘要： The use of devices to simultaneously actuate multiple valves operatively associated with a common combustion chamber is becoming more important due to the increase in multiple valve internal combustion engines. The ability to simultaneously actuate multiple valves reduces weight, costs, and parts in the engine. The subject valve actuation device (10) has a valve arrangement (12) with at least three valves (14, 15 and 16) having stem portions (40, 41 and 42) operatively associated with a common combustion chamber (22). A free-floating bridge (62) having three recesses (64, 65 and 66) is seated on the stem portions (40, 41 and 42). A movable rocker arm (34) having two fingers (36 and 37) contacts the free-floating bridge (62) at locations sufficient to actuate the valves (14, 15 and 16) simultaneously.
