Watching that i suddenly realised I have no idea what the camshafts actually do!

 

I can understand the piston movement. But what the hell is happening top end? I know its to do with timing etc? eh........ someone bail me out please lol

 

:search:

It opens and closes the inlet (air fuel mix) and outlet (exhaust gas) at the specific times to coincide with the stroke of the piston by pushing open the valves.

I understand a fair bit of that but can anyone tell me whats going on with this belt and the wheels/gears its wrapped around ?

Great video btw !

edit - I see an alternator but lost apart from that :)

 

Going around the belt anticlockwise:

1) Crank pulley ;)

2) Aircon compressor

3) PAS pump

4) Idler wheel (to get belt wrap on the alternator and to route the belt run under the front engine mount)

5) Alternator

6) Tensioner

7) Water pump.
