What is the difference between 8 valve and 16 valve car engine?
There are now engines like the Honda V-Tec that have 16 valves and behave as if they were 8 valves when needed.
The valves in the engine are responsible for controlling the entry and exit of gases into the cylinder. (or cylinders) of an engine, its main function is to burn the mixture between air and fuel.
A few years ago conventional engines only came with 8 valvesyes, two for each cylinder. Over time, some automakers have implemented engines with 16 valves, four for each cylinder.
We see 16 valves in one engine meant a breakthrough, because manufacturers were in charge of promoting their 16-valve cars widely.
However, many of us do not know if this is better or worse. That's why here we tell you difference between 8-valve and 16-valve car engine.
These motors have different behavior due to the behavior of the gases as they pass through the duct.
The most common characteristics of 16-valve engines are:
- More peak power with the same displacement, although they get it at higher rpm.
- consume more fuel than 8v
The most common characteristics of 8-valve engines are:
– Have more torque in the mid-range
– Reach less than maximum power
– Less fuel consumption
16-valve engines tend to be more powerful than 8-valve engines at high rpm because by having two intake valves, air enters at a faster rate and with less force than the piston can take than it would in an 8- valve engine.
However, at low speed, this higher air intake rate is lost in the 16-valve, and the 8-valve that has them produces more power than the 16-valve. Currently, variable valve timing systems such as Honda's v-tec system allow 16-valve engines to behave like 8-valve engines at low revs, using only two valves per cylinder e) instead of four, but as their revs increase two other valves open. for better performance.
what are cylinders
cylinders They are the body through which the piston moves.. Its name comes from its shape, roughly speaking, a geometric cylinder.
In vehicle engines, the cylinders are cleverly located along with the pistons, valves, rings, and other control and transmission mechanisms, as this is where the fuel explosion occurs.
The mechanical force of the engine is created in the cylinder, which is then converted into the movement of the car.
