Can anyone here explain what the DOHC means? I'm looking at new ignition leads and plugs ad this term seems to keep springing up.
General 1.2i DOHC 16v?

DOHC stands for Dual Over Head Cams. a 16v car is DOHC. where an 8v is a SOHC (Single Over Head Cam)
Magic, cheers Rampage. Learn something new everyday!

Come to think of it...
Chrysler did/do a 2.0 16v SOHC
Lancia did a Delta Integrale 2.0 DOHC 8v Turbo
Mazda did a 1.3 and 1.6 16v SOHC

It has the answers to everything!!
For example:
Actually, it seems FIAT are rather technologically advanced with engines!

For example:
- FIAT were the first to use DOHC in 1912
- FIAT were the first company to invent a Variable Valve Timing system in 1960, and have the patent for it (shame they still can't make a variator that lasts )
- FIAT were the first to implement VVT into a road car (in an Alfa)
- FIAT were the first to implement direct injection diesel (Croma Mk1)

Sorry Rich, but I disagree.
I just typed in "How many beans make five?" and Wikipedia didn't have a clue what I was on about.
I thought everyone knew the answer - a bean, a bean, half a bean, half a bean and two beans.
SOHC's favourable as its cheap and less parts are liable to break through incorrect installation / operation.
DOHC allows for independent modification of exhaust and inlet timing (with the right pulleys) although from a manufacturing standpoint its more costly and they can be a bugger to install without correct locking tools.

My goodness, that brings back the memories. It's over ten years since my Dad was alive, but he used to say this all the time:
"A bean, a bean, a bean and a half, half a bean, and a bean"
Slightly different to yours!

if you have a SOHC 16v just means you have 4 valves per cylinder not 2 like a typical SOHC, just makes the engine more efficient, and emission friendly.
depnds on what your engine is of course e.g.
4 pot SOHC 16v = 4 valves per cylinder
4 pot DOHC 16v = 2 valves per cylinder 8 for each cam
devide the number of vlaves by the number of cylinders and that tells you how many vlaves per cylinder you got
