What is 16 valve DOHC engine?

An EFI 16-valve 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 engine is the smallest for most European, Japanese and North American cars.

Is a DOHC engine good?

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.

What is the meaning of DOHC in engine?

DOHC means Double Over Head Cam. A DOHC engine design is often called Twin Cam or Dual Cam. It’s the most widely used engine today. The majority of modern cars have a DOHC engine. A typical DOHC engine has two camshafts and four valves per cylinder, like the one in this animation.

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.

Which is better SOHC or DOHC?

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.


The DOHC i-VTEC system enhances the effect of VTEC® by adding Variable Timing Control™ (VTC™). VTC is a hydraulically operated system that controls the timing of the chain-driven intake camshaft, advancing or retarding it during the intake cycle. Civic engines add exhaust-camshaft VTC for even greater precision.

Do DOHC engines have lifters?

With “overhead cam” (OHC) engines, the camshafts are in the cylinder head(s) and actuate the valves directly or via cam followers, so there are no lifters.

What does 1.5 l DOHC mean?

A double overhead cam engine is exactly what the name suggests: a gasoline combustion engine with two cam shafts located above each row of cylinder heads.

Are 16 valves good?

16 valves (16v) means 4 valves/cyl (two each for intake and exhaust). The 16v engine is better in terms of performance as it has an easier time taking in air and pushing out exhaust (i.e, breathing). Now, from a maintenance point of view, 16v is somewhat more prone to problems than 8v in that there is double the no.
