Zusammenfassung: | Due to the increasing population and intense energy consumption,
energy efficiency and efficient use of energy in the power units in the vehicle
are important concepts for our earth. Particularly in hybrid engine vehicles
produced in recent times, Atkinson (or Miller) internal combustion engines are
preferred over conventional internal combustion engines. Atkinson's work from
1882 to the present day in many extended expansion engine mechanism design is
presented. This paper deals with the design of a novel extended expansion
engine mechanism that is intended to achieve trefoil hypotrochoid curve motion
in the crankshaft connection using the planetary gear system. The kinematic
equations related to the presented new crank-conrod mechanism have been
obtained and compared with the conventional crank-conrod mechanism. As a result
of the paper, the equations required for kinematic analysis were derived, and
the kinematic data of the novel designed mechanism were compared and evaluated
according to the data of the conventional system. As a result of this
evaluation, it was shown that the desired extended expansion stroke could be
obtained by using this mechanism and the parameters affecting the kinematic
analysis were determined. However, it has been seen that by changing the
critical design parameters, different piston path can be achieved with the
novel designed mechanism. |
