Fascinating insight into how it works.

Thats great Camerman 8) My son wants to be a mechanic it'll help him to get his head around how engines work :roll: I've been trying to tell him for years but i'm sure it gose in 1 ear, rattles around a bit, then out the other :lol: :lol: :lol:

Wow, thats great, you know its one of thoes things I have always wanted to see.. you kinda wonder what its like... amazing, yet so simple!

hi all.
great bit of filming i wonder how they did it.
just one thing though.
is it my imagination or is part of the cycle missing.
the exhaust stroke.

TWIN SPARK WITH CAMERA DOWN OTHER PLUG HOLE? 4 valves with only two doing anything could be a yamaha or audi 20v engine an thyeve took valve out

It's there but not as long as I would have thourght :roll:

exaust usaully quicker as its being forced out by up comming piston, why the exuast valve usally smaller than inlet

Interesting but what's that thing in the middle with a spark :lol: just looked at my T2 but nothing like that in there :roll:

ha ha diesel engine just take away plug and its virtualy same fuel may be direct on some engines!

 

[bigjim]

Only looks to me like only two cycles are shown, then shown again, i am pretty sure its not showing all 4 cycles 8O

Wot? The piston is connected to the crankshaft by a con rod, the other con rods connect to the other pistons and other journals on the crankshaft, the crank therefore cycles ALL the conrods and pistons at a uniform speed.

If one piston moved faster than the others it would cause an inbalance in the engine resulting in a vibration. Good engine rebuilds should therefore have ALL the conrods and pistons weighed seperatley and the heavier ones have material removed by drilling or grinding to even them out giving a balanced engine

The Inlet valve is bigger so the vacuum of the inlet stroke can draw as much of the fuel/air mix in as possible, thats why intercoolers gives an increase in power as it cools the expanded hot air intake thats been through a heated exahust driven turbo unit to allow more air into the cylynder, more air/oxygen bigger bang basically

 

[jace]

yes but easier to push stuff out than suck in didnt mean cylinders worked quicker than one another

 

[drivewasher]

Sorry Jace, I didn't read your post properly, thought you meant the piston moved quicker on exhaust

we werent that posh at colege we had cut away single cyl to show us but we did have a rotary engine cut down aswelll tutors pride joy lol
