Title: Cylinder head of internal combustion engine
Inventor: MIZUNO TEI
IPC: F01L3/08
Filed: 1989-04-26
Abstract: PURPOSE:To reduce the man-hours for processing and eliminate necessity for provision of reinforcing fillets associate with pressure fitting by forming valve guides, for penetration of a suction valve or an exhaust valve slidably, in such a way as in a single piece with a cylinder head. CONSTITUTION:At a cylinder head 30 cam shafts 18, 19 are arranged so that their axes L1, L2 are located on extensions of the axes L3, L4 of valves 7, 8.
