Is it possible for car manufacturers to make 32 / 64 / 128 / 512 Valve Car Engine just like in a PC CPU? The highest valve I saw so far is 16-valve engine. Just asking :-)
:-) Good one! But in case you are serious, number of valves makes sense when connected to the number of cylinders. When some ford puts 16valve decal on the trunk it's completely meaningless because for a 4 cyl engine it would constitute 4 valves per cylinder, for an 8 cylinder engine - 2. So far, the highest number of valves in standard vehicle has been 5. PER CYLINDER. Reasons: 1. enough, 2 - technological.
There's no point. 4 or 5 valves per cylinder are enough for almost every automotive application. Or are you getting valves and cylinders mixed up? Even in that case, there's no point. Eventually the complexity and weight cancel out any benefits you'd get from the added power it could create. Also, you would eventually have too much torque for the crank to take without being ridiculously thick and heavy, further increasing the weight of the engine, or serving as a limiting factor for maximum engine size. Waitasec...you ARE getting them mixed up. There are plenty of 24 and 32 valve engines out there (3 and 4 valve per cylinder V8s) . Valves are parts on the top of the cylinder that let IN air (and in some cars, fuel), and let OUT exhaust gases. The more valves per cylinder, the more freely these gases can flow...but past a certain number, additional valves are pointless. The most CYLINDERS in an automotive engine in current production is the Bugatti Veyron's 16 CYLINDER engine, which has 4 VALVES for each CYLINDER, for a total of 64 VALVES.
There would be no point to having such high valve count. The point of more valves is to cover the cylinder head combustion chamber with flow spaces. Topologically this is pretty well done with 4 or 5 valves. It is very expensive to add the 5th valve so most manufactureres are happy with 4 valves/cylinder. The largest 4valve / cylinder engine in mass production would be the GM/Caddilac Northstar V-8 IIRC. More analogous to your CPU question would be the use of multiple cylinders, not valves. As far as I know, the largest mass produced engines for auto use have been V-12's as found on high end BMW's and Jaguar's. At a given displacement, engines become more powerful and efficient with more cylinders. Go figure, just the opposite of PC CPU's! I'm sure there are large stationary or ship engines that are made with 32 cylinders, maybe more. The largest I've seen though had 24 and was used to generate electricity for a corporate campus.

I'm sure they could if they wanted to. The problem is the more moving parts you have the problemms you will have and the more it will cost.
