Why DOHC is faster than SOHC?

A DOHC, four valves per cylinder configuration allows better airflow at high engine speeds, resulting in better top end power. To sum it up, a 4 Valve per cylinder SOHC engine with a lighter valvetrain mass would have better performance characteristics at the lower end of the powerband.

Can I put a VTEC head on a non VTEC engine?

Yes, as long as the engines are the same series, they should be interchangeable. The engine blocks, pistons, and crankshafts for all of the Accord/Prelude/Odyssey/CL F22Ax/F22Bx engines are basically identical, and the heads for any of them will bolt down and operate normally with any of the blocks.

What is SOHC vehicle?

SOHC. Single overhead cam or overhead cam engines have a single camshaft installed in the cylinder head. The valves are operated directly by the camshaft and it is much easier to maintain precise timing at higher RPM and 3 or 4 valves per cylinder.

What is the difference between SOHC and DOHC?

As you can see, SOHC engines have only one camshaft and that lone camshaft operates both the intake and exhaust valves. In comparison, SOHC engines produce less power than DOHC engines. But the upside of having a SOHC engine configuration is that it’s simpler and cheaper to manufacture, as well as lighter than DOHC engines.

What is the difference between an OHC and SOHC engine?

OHC or SOHC engine. OHC means OverHead Cam in general, while SOHC means Single OverHead Cam or Single Cam. In a 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 this animation). See this photo of a Mitsubishi SOHC engine.

What is a DOHC engine?

As mentioned before, DOHC engines have two camshafts, one that operates the intake valves and the other that operates the exhaust valves. DOHC engines are considered to be more flexible in nature as they have more accurate control over valve lift and timing, and are generally the go-to for multi-valve engines.

How many valves in a SOHC engine?

SOHC engine valve configurations typically have 2 or 3 valves per cylinder. It is also possible to have 4 valves per cylinder using SOHC but this translates into a complicated combination of rocker arms and cam lobe shapes.
