Thanks.

To what I know rotary engine have no cams.

[Octopus]

pushrods are still driven from a camshaft..

the camshaft is what open and closes the valves at the correct time..every 4 stroke engine has camshafts...2 stroke engines does not..

Is that because 2 stroke engines does not have intake and exhaust valves? I think they using 'port' instead of 'valves'?

[Brad]

yep

they have ports , and one way valves called "reed valves"

[Octopus]

Errrr... reed valves is something new to me..... can briefly explain what do reed valves do?

overhead camshafts will open the valves directly from the camshaft ,where older V8 pushrod engines has a cam that is in the centre of the engine block , then pushrods sit onto the camshaft and the rods come up through the head and push on a lever (called a rocker arm) that pushes the valves open..

 

Brad..

 

So we call these.. Single or Double "Underhead cams"....

[Brad]
