EXHAUST PORT STRUCTURE OF A CYLINDER HEAD WHEREIN EACH EXHAUST PORT IS IDENTICAL OR SYMMETRICAL WITH AN EXHAUST PIPE AS A CENTER

摘要

PURPOSE: An exhaust port structure of a cylinder head is provided to integrate an exhaust manifold with an exhaust port of a cylinder head and even with an EGR(Exhaust Gas Recirculation) line, whereby a separated pipe for the EGR line is removed and the weight of the cylinder head is reduced.;CONSTITUTION: An exhaust port structure of a cylinder head includes an EGR line(30) and an exhaust pipe(40). The EGR line is extended to a connection pipe to be integrally formed. Each of the exhaust ports(11,12,13,14) is formed with the identical or symmetrical shape with the exhaust pipe as a center. The exhaust pipe extended from the connection pipe is formed on the position corresponding to the entry of a turbo charger.;COPYRIGHT KIPO 2013
