Abstract

"MéTODO PARA ESTIMAR O ENCHIMENTO DE UM CILINDRO EM UM MOTOR A COMBUSTãO INTERNA". Equipado com um sistema de variação de golpe de came (10). é estimada a eficiência de indução teórica (<sym>~ thr~) que o cilindro (2) teria caso operasse com um valor de tempo de indução/exaustão ideal (VVT); a mencionada eficiência de indução teórica (<sym>~ thr~) tem seu valor reduzido por um fator de correção (K~ VVT~) que depende do valor de tempo de indução/exaustão (VVT) realmente utilizado para estimar a eficiência de indução (<sym>~ asp~), que é a medição padronizada do enchimento do cilindro (2).
