Valvetrains of four stroke combustion engines
Přeslička, Jaroslav ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
The thesis deals with technical solutions of four stroke piston engines valvetrains, their advantages and disadvantages. First it describes four stroke engine working cycle and outlines the problems of valvetrain timing. Then follows the description of valve design, camshafts, types of cams and valve lift course. Another part of the text occupies with SV, OHV, OHC and unconventional valvetrains. The following part is focused to the ways of camshaft drive. The last part is engaged in variable valvetrains. At the end there is indicated the future of combustion engines valvetrains.
