Cam Profile

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” when ensuring working capacity and reliability of the valvate drive. One of the main directions of improvement of fuel pumps of high pressure of diesel engines is increase in the maximum pressure of injection. In this work it is offered to improve a numerical method by imposition of the restriction on the first derivative of movement of the pusher on a cam angle of rotation, that is a pusher speed analog. This restriction allows to receive a cam with the site of constant maximum speed of the pusher. It allows to increase the maximum pressure of injection.
