    calcul TI
-regime moteur 4250tr/min

-nbre cycles 1 cycle pour 2 tr
donc 2125 cycles/min

-conso 150g/40s soit 225g/min

-conso/cycle 225/2125=0.106g/cycle

-conso/cycle/cyl 0.106/4=0.265

-debit injecteur 120g/min

-temps ouverture pour 0.106g 
0.106*60/120=0.053s soit 13.25ms

-Ti applique sous 13.8V
13.25ms+0.650ms=13.9ms

-angle vilo 4250tr/min
4250*360=1530000deg/min

-angle vilo pour Ti=13.9ms
354deg vilo

debit statique=Qm
Qm=K*p*S*sqrt(deltaP)
K=coeff debit injecteur
S=section passage du carb
p=masse volumique

comb homogene=carb injecte admission
comb stratifiee=carb injecte compression
tumble=mvmt brassage air carb due a forme piston
trop tumble=debit air diminue
capteur de cliquetis=piezo-elec

stratifie pour la depoll
homogene pour la perfo
transition entre les 2 se fait avec la transition
du mode homo avec richesse elevee
