Abstract

Patente de Invenção: "MOTOR DE COMBUSTãO INTERNA QUE POSSUI UM MEIO DE REDUçãO DOS ACICLISMOS PARA OS FUNCIONAMENTOS EM BAIXO REGIME". A invenção refere-se a um motor de combustão interna, do qual o virabrequim (1) é munido de uma polia ou de um volante de inércia (4) solidarizado com ele por meios de fixação, no qual o dito volante de inércia (4) é munido de pelo menos um elemento pendular (45) do qual o dimensionamento, a massa e o posicionamento no dito volante de inércia (4) são determinados de modo a ser ajustados próximo da pulsação do harmónico maior do aciclismo.Invention Patent: "INTERNAL COMBUSTION ENGINE THAT HAS A MEANS OF REDUCING ACCYCLISMS FOR LOW REGIME OPERATIONS". The invention relates to an internal combustion engine, of which the crankshaft (1) is provided with a pulley or a flywheel (4) attached to it by means of fixation, in which said flywheel (4) ) is provided with at least one pendulum element (45) of which the dimensioning, mass and position on said flywheel (4) are determined so as to be adjusted close to the pulse of the major harmonic of the acyclism.
