What is the meaning of 16 valve engine?
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).
What is the meaning of DOHC in engine?
Dual Overhead Camshaft
To put it shortly, DOHC refers to Dual Overhead Camshaft, SOHC refers to Single Overhead Camshaft, and OHV refers to Overhead Valve. To better understand what these mean, it is important to know how a typical 4 stroke engine works (this is the type of engine you would find in any modern car).
Is a 16 valve a 4 cylinder?
That leaves 4 or 8; either a 4 cylinder engine with four valves per cylinder, or an 8 cylinder engine with two valves per cylinder. Since two valves per cylinder is the minimum possible, it’s unlikely that a 16-valve eight cylinder engine would be described as such, so a “16 valve” is almost always a four cylinder.
Is 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 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.

What is the difference between DOHC and OHV?
The main difference is in the placement of the camshaft. OHV means Over Head Valve. OHC stands for Over Head Cam, or the camshaft is installed in the cylinder head. SOHC means Single Overhead Cam, while DOHC means Double Overhead Cam.
Are all cars DOHC?
DOHC means Double Over Head Cam. A DOHC engine design is often called Twin Cam or Dual Cam. 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.
Do V16 engines exist?
The first use of a V16 engine was in the 1910 Antoinette VII experimental aircraft, followed by several cars in the 1930s. Today, the most common applications for V16 engines are railroad locomotives, marine craft, and stationary power generators.
What does DOHC mean on engine?
DOHC or Double Overhead Camshaft refers to the car engine’s valve train with two camshafts. This valve train layout or configuration is common in cars today, replacing the previous version – SOHC or Single Overhead Camshaft. Engines with the DOHC layout are said to generate more power and increase fuel efficiency.
What is an EFI 16 valve DOHC?
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.
What is the DOHC engine?
DOHC engines allow for multiple valves in a cylinder and are specifically designed to increase engine efficiency. The double camshafts of a DOHC configuration maximize the engine’s output through the multiple valves setup, without any increase in the overall volume.
What is a cylinder head valve?
A valve head, or cylinder head as it is more commonly called, is a piece of an internal combustion engine that contains and houses the intake and exhaust valves. The head sits on top of an engine directly over the pistons and encloses the combustion chamber.
