OTTO MOTOR DYNAMICS
Otto engine dynamics are similar in almost all common internal combustion engines. We can speak
so about dynamics of engines: Lenoir, Otto, and Diesel. The dynamic presented model is simple and
original. The first thing necessary in the calculation of Otto engine dynamics, is to determine the
inertial mass reduced at the piston. It uses then the Lagrange equation. The dynamic equation of
motion of the piston, obtained by integrating the Lagrange equation, takes a new form. It presents a
new relation which determines the elastic constant of the crank shaft, k. The moment of inertia 1 J
can be determined with an original relation, as well.
