first , its good animation . but plz ... i wanna understand more .so,i ask : why we need the lead and lag period or ( what is the benefit of opening inlet valve after BDC even there is no more charge entering and the same idea for lead >>>) the last ques. is (Is the sum of lead + lag considered an overlap also ) ???? ... Thx in advance ......
moh saeed I think the idea is to use the momentums of the gas flow. The camshaft design collaborates with the inlet and exhaust header design. So you can overcharge the engine and increase the volumetric efficiency.
Depends we are talking about. This video is for a 4 strokes engine, in wich one cycle (the four strokes) is completed when the crankshaft realize two turns (720 degrees). On the other hand, a 2 strokes engine would complete the cyclo in only the 360 dregrees that you say (one turn of the crankshaft). Regards.
thanks english lady!

I thought I learned this on roadkill... apparently now I’m more confused ....but totally enjoyed the video
How do I find the original video?
but sir rrb according ans.vavle duration call. this question i objetion my ans.is valve overlep my ans.will right after revised ans.key .tell me sir
Very nice!!
inlet or ekjost valve ak sath kulne ko kya khte h 23 january 1st sift part b diesal macenic
23 january 1st diesal Macenic (Ques.inlet and akjost value are both opened some dgree this condition is speak ?) plz tell me sir
Yes , its called valve overlap , this happens near end of exhaust stroke
wait wait others should have 360 degrees to finish the cycle? im confuse
