Is 16V better than 8V?
8V = better low end torque, smoother and more power at low rev, higher fuel consumption, higher emission…. 16V = better high end torque, high reving, lower fuel consumption, lower emission…
What does 16V mean?
The 16V means 2 intake, 2 exhaust for each cylinder, and TYPICALLY indicates a more powerful or higher performance engine, but not always. This concept is carried over to larger engines as well, for example, a 32V most likely refers to a DOHC V8 engine with 4 per cylinder.
How many valves does an 8 cylinder have?
V8 engines – 32 valve or 24 valve.
What size engine is a 16 valve?
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.
Why more valves are better?
More valves equal better airflow and a more efficient engine. Smaller valves are lighter, which means the engine can rev higher, create more power, and in general, look down upon the two-valve engines of the world with a sense of multi-valve satisfaction.
What cars have a 16 valve engine?
The Short and Intriguing History of V-16 and W-16 Engines

- 1988 BMW 767iL Goldfisch.
- 1989 Mercedes-Benz 800 SEL.
Is 16 valve a V6?
The Camry is with an inline 4 cylinder engine. There is no V4 engine!! And the 16 valves are not for the V6 but for the I-4.
Which is better 2 valve or 4 valve?
A two-valve per cylinder layout is simple and cost effective. A four-valve system may be more capable, but it’s more complex and more difficult to design and produce. To get a four-valve layout right from a metallurgy and thermodynamics perspective is way more difficult than a two-valve setup.
Does a 4 cylinder have 16 valves?
Four valves per cylinder, dual overhead cam and electronic fuel injection are some of the features of a 16-valve DOHC engine. These engines are often used in compact trucks. The 16-valve four-cylinder engines are from earlier engines.
Why is 4 valves better than 2?
4 valves per cylinder allows for more airflow than 2 valves per cylinder, as there is larger open area when the valves are open. Having a configuration with DOHC and four valves per cylinder means better airflow, especially at high engine speeds, resulting in better top end power.
Are bigger valves better?
Answer: It depends on the type of cylinder head. Generally, if the cylinder head was designed for street applications larger valves will not improve air flow. Often tines, large valves will actually decrease air flow. Thinking that “bigger is better” many people install 1.90″ or 1.94″ intake valves in 305 heads.
What’s the difference between 8 valves and 16 valves?
Figo diesel Engine -Valves are 8 whereas for swift , it is 16… I was told that less number of valves will increase Maintenance of the car that means Figo will have more maintance than Swift. is that true? ur suggestions…….
Is there an 8 valve Golf GTI engine?
On the heels of the 16-valve outputs thread, I’ve now compiled a stack of data on the original Golf GTI 8-valve engine. Production (UK, Europe, USA, Canada), tuner engine packages, all the way through to works rally, rallycross, Super Vee and F3.
How many valves does an 8v engine have?
Well 8 valves (8v) basically means a 4-cyl engine with 2 valves/cyl (one for intake and one for exhaust).
Which is better an 8V or a 16V engine?
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. of valves to take care of than an 8v engine.
