Default RE: DOHC vs. SOHC

Single overhead camshaft (SOHC)
Found in 2,3,4 Cylinder Models.

[/align] [/align] [/align]In the SOHC engine the camshaft is installed in the cylinder head and valves are operated either by the rocker arms or directly through the lifters (as in the picture).

Pros: Valves are operated almost directly by the camshaft - easy to achieve the perfect timing at high rpm. Also it's possible to install three or four valves per cylinder. The SOHC design has less reciprocating mass than a comparable pushrod design. This can allow for higher engine speeds, which in turn will increase power output for a given torque. Con: OHC engine requires a timing belt or chain with related components - more complex and more expensive design.

Dual overhead camshaft (DOHC)
Found in 4(some),6,8,10,12 Cylinder Models


DOHC or Double OverHead Cam - the setup used in many today's cars. Since it's possible to install multiple valves per cylinder and place intake valves on the opposite side from exhaust vales, DOHC engine can "breath" better meaning that it can produce more horsepowers with smaller engine volume.

Pros: High efficiency, possible to install multiple valves per cylinder and adopt variable timing.
Cons: More complex and more expensive design.

You my friend are blessed with the DOHC with VTEC.

Calm yourself. This is an Accord forum for helping others, newbies or pros, new or old, etc.

You a smurf of FASTACCORD?
