DOHC

Lord-Atak · 01-24-2001, 07:52 PM

Well i dont know if this should go in here but its kinda about the WRX. On a DOHC engine is there 2 cam shafts and what does a cam do? As you can see I don't know all the techy stuff.

Dual Over Head Cam's dohc
cam's over the head as apposed to in the block ie. v8 motor's. (not all though)
the cam's operate the valves.

To expand on that,The cams operate the valves which open and close the entrys into the combustion chambers where the fuel is ignited and burned. Also the exits to the combustion chamber where the spent innert gas is then passed into the exhaust.

On the new WRX there are 4 cams, two per cylinder bank. You have got to allow yourself to be exposed to the wonders of the internal combustion engine. It's a wonderful thing. Get some books and fine a cheap little motor, tear it apart, put it back togeather. Don't rush, its fun.

Yeah, one camshaft controls the intake and the other controls the exhaust.
