Summary: This project is designed to explore possibilities to obtain
optimal cam profile of the fuel injection pump with use of methodical
construction with computer support. Several versions of cam profile was
tested and thereafter critical analysis of each version was made.
Following evaluation of each profile, the best version was optimized in
order to maximally achieve given aims of this research project.
Research goals: The primary aim is to seek optimal cam profile of
the fuel injection pump on basis of principle of methodological
construction, which shall to the highest grade meet list of requirements
which modern system of fuel injection requires, and they are: - to reach
sudden speed increase of the piston, - to reach high speed of fuel
injection, - possibility to withstand high pressure tension, - to obtain
sufficient lasting, etc. Programmes used for cam profile optimization are
universal and give possibility for critical analysis and construction of
characteristic curves: erection, speed and pressure angle, pressure angle
and maximally permitted pressure of pumps. Accordingly it will be possible
to determine beginning and end of supply, marginal rotating speed,
permissible pump pressure, and by that lasting of cam shaft. Suggested
solution for cam profile optimization shall give possibility to designers
of fuel injection system to determine design phase optimal cam profile of
injecting mechanism, by which very expensive production of prototypes will
be avoided as well as possibility for premature pump damage in later phase
of serial production.
