Selection of cam mechanisms for driving the plunger of high-pressure pump of diesel engines using Mathcad program
The purpose of the article is to select the cam profile (with equal design parameters) for driving the plunger of a high-pressure pump that provides the maximum speed and permissible acceleration of the pusher. A method of selecting a cam profile by analyzing combined graphs of changes in the p...

| description | The purpose of the article is to select the cam profile
(with equal design parameters) for driving the plunger of
a high-pressure pump that provides the maximum speed
and permissible acceleration of the pusher. A method of
selecting a cam profile by analyzing combined graphs of
changes in the path, speed, and acceleration of a cam
pusher of various profiles using the Mathcad program is
proposed. Calculations have been performed and combined
graphs of changes in the path, speed, and acceleration
of the cam pusher with tangential, convex, and concave
profiles have been constructed. A comparative analysis of
the combined graphs showed that the maximum speed
of the cam pusher with a concave profile is 1,5 times
greater than for cams with a tangential or convex profile.
A cam with a concave profile is recommended for driving
pump plungers of low-speed marine diesel engines (up
to 250 min–1). To create ultra–high pressures (more
than 120 MPa), the fuel supply system must be batterytype with a drive of small diameter plungers (4–6 mm)
from an eccentric shaft with a special-shaped washer and
electronically controlled injectors.
