Nominal and maximum frequency of rotation
The internal combustion engine reaches the maximum capacity at a certain frequency of rotation – so-called nominal frequency of rotation. The set of bigger number of turns does not give a prize on capacity. He can be of use good service unless for switching on the following, highest transfer.
It is quite possible to call our engines steady against the increased frequency of rotation. The drive of valves is carried out by means of tarelchaty pushers directly with located at the top of a camshaft. Thus only small masses that allows to develop high frequency of rotation without danger to a drive of valves are given in movement.
Turns of the engine can be lifted to about 6300 rpm only for short time. The engine then considerably "growls" that is caused by fluctuations of a cranked shaft in its bearings.
