I’m a noob car guy, learning more every day.
I’ve had I think 14 cars in my 7 years of being licensed, and in that time I’ve heard a lot of people mention something like “oh the 12v is better than the 16v” when talking about two models of the same car.
What’s the significance, what does it do?
I have a basic understanding of how a combustion engine works, if that helps.
In: 1
Four valves per cylinder allows for larger intake/exhaust ports, lighter valves, and softer valve springs. Larger ports means less pumping losses; power from the engine goes to the wheels instead of being wasted trying to force air in and out. Lighter valves can reverse direction between opening and closing easier, which allows the engine to rev higher. Lighter valve springs are more reliable/durable since there’s less force to cause metal fatigue.
