Numerical cam profile design with tappet constant speed section in internal combustion engine valve gear and fuel system

In modern internal combustion engines the drive of valves of the mechanism of gas distribution and a plunger of the fuel pump of high pressure is carried out by the cam mechanism. The functional requirement imposed to gas distribution mechanism cams is receiving the greatest valve “time-section” whe...
