no, the timing on the intake valve is wrong... it's open during the upstroke, not the downstroke like it should be. there are also times when BOTH valves are open.
The timing is perfect. (red is intake, blue is exhaust.) IF IT WERE a 2-cylinder engine it would be out of BALANCE because there are 180-degrees between power strokes and it takes 720-degrees to complete the 4-stroke cycle. Therefore a more normal 2-cyl engine would fire every 360-degrees. (Don't get me started on Harleys!) The representation is probably only showing 2-cylinders of an immaginary 4-cylinder engine, and is therefore correct.
The timing is correct for a twin cylinder inline 4 stroke. The red valves are inlet and the blue are exhaust. The crank positions are never directly opposed for a inline twin cylinder always 90degree stagger, for a harly engine on the other hand both pistons use the common crank with different timing.
wow i really like that it is absulutley brilliant i just wanna no if there is a engine avalible on the web for download plz reply even a simple one will do
you just define the contact with the cylinder (transparent) and the pin (light grey).

@bobjims i was talking about right before the compression stroke on the closest cylinder. but i could be wrong im not perfect.

to all the know-alls..your daddy got the timing wrong

the red opens way early see
magicmechanic86 2 years ago
the timing is off look at the left cylinder both valves are shut while the piston is rising in one of the revolutions........

@magicmechanic86 That is the compression stoke, both valves must be closed during this stroke.

What's wrong with the timing? It looks like a 4 stroke cycle to me; what am I missing?

Timing is wrong man. the valves is not following the pistons.
