Contributii la sinteza mecanismelor de distributie ale motorarelor cu arbere interna cu metoda coordonatelor carteziene

摘要

The work presents a few polynormial lasws of pusher movemnet of ht edriving mechanims form internal-combuistion engines. It present the way to get and maximlalize these laws.having in view a few principal criterions,such are: -the achievement so fthe biggest chronosection; - the smallest valves for hte speed,for the acceelrations,the accelerations of the order two (2) adn the continuity of th emovement law and it' s dervatives ,going on the possible hihger order ,specially for the extremities of the interval.
