Nominal and maximum frequency of rotation

The internal combustion engine reaches the maximum capacity at certain frequency of rotation – so-called nominal frequency of rotation. The set большего number of turns does not give a prize on capacity. He can be of use good service unless for switching on following, higher transfer.

It is quite possible to name our engines steady against the raised frequency of rotation. The drive of valves is carried out by means of тарельчатых pushers directly with located at the top of a camshaft. Thus in movement small weights that allows to develop high frequency of rotation without danger to a drive of valves are resulted only.

Engine turns can be lifted to approximately 6300 rpm only for short time. The engine then considerably "growls" that is caused by fluctuations of a cranked shaft in its bearings.
