Quick Answer: What Is Sohc Engine?

Which engine is better SOHC or DOHC?

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.

Is SOHC a good engine?

SOHC engines are fuel-efficient, but DOHC can reflect more fuel efficiency depending on the design of the engine and the skills of the driver. The Dual Overhead Camshaft also has a better valve timing compared to its counterpart.

What does SOHC engine mean?

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.

How do I know if I have DOHC or SOHC?

Re: how to tell if you have a SOHC or DOHC? Easiest way to tell is by looking at the valve cover, the DOHC is much wider and has a groove in the middle where the plug wires go.

Is DOHC better than VTEC?

Just wondering what are the main differences between DOHC vtec and SOHC i-vtec. Essentially speaking the biggest difference is the number of camshafts the engines have. DOHC engines are designed to rev higher, have peakier power outputs and PERHAPS high horsepower application.

Can you convert SOHC to DOHC?

you can‘t convert a sohc motor to dohc period.

Why does Honda still use SOHC?

SOHC engines are cheaper and less complicated to design, build and maintain because of the lesser moving parts, while DOHC are more complex to design build and repair because of the extra moving parts.


VTEC is a Honda trademark, and SOHC is a single-cam engine (Single OverHead Cam). VTEC allows for higher power or better economy (and later, better inroads to a little bit of both) by allowing for different valve lift profiles based on ECU control (usually RPM and load, or other similar factors).

How much horsepower does a 4.0 v6 have?

Ford 4.0L V-6 Specs

Engine: Ford 4.0L V-6
Peak Horsepower: Various ratings, including: • 155 hp- 160 hp @ 4,200 rpm (OHV) • 210 hp @ 5,250 rpm (SOHC) • 207 hp @ 5,250 rpm (2011 Ford Ranger)
Peak Torque: • 225 lb-ft @ 2,400 rpm (OHV) • 254 lb-ft @ 3,000 rpm (SOHC) • 238 lb-ft @ 3,000 rpm (2011 Ford Ranger)


Dohc means duel overhead camshaft and VTEC is a technology for variable valve timing and electronic lift control.it is a technology developed to control the lift of valves at different speeds.

What cars have DOHC engine?

Examples of DOHC engines:

  • Ford 3.5L EcoBoost V6 DOHC.
  • Ford Mustang Boss 302 5.0L DOHC V8.
  • Ford Mustang 5.2L V8 Supercharged.
  • BMW S65 DOHC V8.
  • Infiniti 3.0L VR30.
  • Mercedes-Benz Inline-6 DOHC engine.

How many camshafts does a SOHC engine have?

A SOHC engine has one camshaft per bank of cylinders, therefore a straight engine has a total of one camshaft. A V or flat engine with a total of two camshafts (one per bank of cylinders) is a single overhead camshaft engine, not a double overhead camshaft engine.

What is 16 valve DOHC engine?

An EFI 16valve DOHC is a four-cylinder engine with four valves per cylinder, dual overhead cam and electronic fuel injection. Most engines with these features have a displacement of 2.4 liters or less. The 16valve four-cylinder engines derived from earlier 8- and 12-valve four-cylinder engines.

Why is a SOHC more preferred over an OHV engine?

An SOHC generally uses two valves per cylinder while a DOHC uses four valves per cylinder. Summary: “OHV” means “overhead valve” and “OHC” means “overhead camshaft” configuration of the cylinder head. The OHV is a more compact design but less efficient while the power output is higher as compared to an OHC.

How does a DOHC engine work?

Generally, engines with dual overhead camshafts (DOHC) are higher performance engines, they produce more power, and can run at higher speeds. The camshaft uses rotating lobes, called cams, that push against the valves to open them. Springs on the valves return them to their closed position.
