Conclusion – SOHC VS DOHC As we noted, SOHC is simpler to make and cheaper, also more fuel-efficient since it has a lower number of valves. DOHC on the other hand has more valves and produces more power. Making it more expensive to produce and to run.

Are DOHC engines more fuel efficient?
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 better valve timing compared to its counterpart.
What is the advantage of DOHC?
A DOHC, four valves per cylinder configuration allows better airflow at high engine speeds, resulting in better top end power. DOHC engines also allow the spark plug to be placed right in the middle of the combustion chamber which in turn promotes efficient combustion.
Which is better DOHC or SOHC?
DOHC is better for performance because you will get more horsepower with it. SOHC is better for reliability. A SOHC engine contains much lesser parts, which will make it more reliable.
Why does Honda still use SOHC?
SOHC cams mean that the engine head can be smaller and lighter, but they aren't as efficient as DOHC. DOHC means there are two camshafts, one operating the intake valves and one for the exhaust valves. These allow for more accurate timing, and therefore create more power and work more efficiently.
Can you convert a SOHC to DOHC?
you can't literally convert a SOHC to a DOHC, either buy a vtec head, new ecu, and a vtec selenoid or just buy a whole new motor.. if your looking for a big gain, just swap motors.. for like 20ish hp just get the vtec head.
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.
Does DOHC mean Turbo?
Dual overhead cam engines are found in most modern vehicles today. They allow better airflow with less obstruction and are generally much more efficient engines than OHV or SOHC engines. Two camshafts operate 4 valves per cylinder, one separate camshaft for intake and exhaust valves.
Are more valves per cylinder better?
While enhanced engine breathing owing to better air flow is one of the biggest advantages of more valves per cylinder, it's not the only one. ... Being lighter, the smaller valves also put lesser pressure on the camshaft lobes which control their lift, and if well-engineered, can enhance the durability of the engine.
Is DOHC VTEC?
The original VTEC system was introduced in Honda's DOHC (Dual OverHead Camshaft) engines in the 1989 Honda Integra XSi and was first available in the United States in the 1991 Acura NSX. ... By introducing the option of two camshaft profiles combined with variable valve timing, Honda optimized the performance even further.
Why is SOHC preferred over OHV?
Less common than say DOHC and OHV, but it's not to say it's worse. Due to only having one camshaft for each bank of cylinders, the Single Over Head Cam is lighter and simpler than it's twin cam counterpart. And because there are less components, it's cheaper to make as well.
How does SOHC VTEC work?
The basic mechanism used by the VTEC technology is a simple hydraulically actuated pin. This pin is hydraulically pushed horizontally to link up adjacent rocker arms. A spring mechanism is used to return the pin back to its original position.
Do DOHC engines have lifters?
In a DOHC engine, the lifter acts directly on the valve stem's head. The lifter might have another name, but it serves the same purpose. Some DOHC engines have self- adjusting, hydraulic lifters, most are adjusted by shims.
Do DOHC engines have rocker arms?
DOHC engines lead to easier implementation of multivalve engines, as they don't require rocker arms and other supporting hardware for each valve, thus allowing for easier and more efficient breathing of the engine.
Is a 16-valve engine good?
In 16-valve engines, there are 4 valves per cylinder, two of which are responsible for intake and two for exhaust. ... Sixteen-valve engines are characterized by better power and good fuel efficiency, but they are more demanding on maintenance, which can significantly increase the costs of the car owner.
