Realistic values have been chosen for the parameters of this cam-follower mechanical system, and the checking of this modified mathematical model has been accomplished by means of a qualitative comparison with other models previously conceived, and with previous experimental results obtained from an automobile engine. The digital computer simulation allows the determination of the cam speed for which the valve toss occurs, whose value is of fundamental importance in evaluating the design of automotive cam mechanisms. <\/jats:p>","DOI":"10.1177\/003754979306000605","type":"journal-article","created":{"date-parts":[[2008,3,29]],"date-time":"2008-03-29T17:23:43Z","timestamp":1206811423000},"page":"407-417","source":"Crossref","is-referenced-by-count":0,"title":["Determination of the Toss Speed for an Automotive Valve-Gear System"],"prefix":"10.1177","volume":"60","author":[{"given":"Jos\u00e9 A.","family":"M\u00e9ndez-Adriani","sequence":"first","affiliation":[{"name":"Deponent of Design Mechanical Engineering Central University of Venezuela Caracas, D.
