VTEC




VTEC (Variable Valve Timing and Lift Electronic Control) é um sistema de comando de válvulas variável, desenvolvido pela Honda em 1983, para aumentar o torque dos motores em baixas e altas rotações. Foi inventado pelo engenheiro da Honda, Ikuo Kajitani.


O sistema VTEC utiliza dois perfis de árvore de cames, selecionando hidraulicamente.


É diferente do sistema VVT da Toyota, que avança apenas o sincronismo da válvula e não altera o perfil da árvore de cames [1].

Probability when a professor distributes a quiz and homework assignment to a class of n students.

Image
0 0 $begingroup$ Need help with this problem. Suppose our lazy professor collects a quiz and a homework assignment from a class of n students one day, then distributes both the quizzes and the homework assignments back to the class in a random fashion for grading. Each student receives one quiz and one homework assignment to grade. (a) What is the probability that every student receives someone else's quiz to grade, and someone else's homework to grade? (b) What is the probability that no student receives both their own quiz and their own homework assignment to grade? In this case, some students may receive their own quiz, and others may receive their own homework assignment. (c) Compute the limiting probability as n approaches infinity in each case. ...

Are they similar matrix
