8v - 16v The difference?

Question

8v - 16v The difference?

Answer 1

its v8 and v16 mean 8 cininders for example, camaros and most chevys and such have v8s but lambos have v16s

Answer 2

Depends. Do you mean 8Volts Minus 16Volts? in which case the answer is Negative 8 Volts. If you are comparing 8V to 16V then the answer is 8V.  16V has twice the potential as 8V.

Answer 3

The v stands for valves - they're what an engine 'breathes' with, they allow the air & fuel mixture in & the exhaust gases out of the engine.

Bigger area of valves means better flow of gases & therefore more power - valves are round & therefore, engine design means that they can only be of a certain size, so you need more valves rather than bigger ones to fit in an engine - hence 16 valves are better than 8!

Answer 4

the difference is 8v

Answer 5

assuming your talking about intake and exhasue valves...8 valves would be 2 valves per cylinder(1 intake and 1 exhaust)  on a 4 cylinder engine.  The intake valve lets air/fuel mixture into the combusdtion chamber where the piston then compresses it and combustion occurs, then the exhaust valve and the exhaust from the combustion is then forced out of the combustion chamber to the exhaust system.  16 valves would be 4 valves per cyliner(2 intake and 2 exhaust) in a 4 cyclinder engine, which allows for more fuel air to enter into the combustion chamber and the extra exhaust to exit, more fuel means more power.

Answer 6

It is the valves (inlet and exhaust valves) which allow the cool gulp of fuel/air mix into the engine, and the hot slug of exhaust gas out.  In the old days, most engines had just one of each valve per cylinder, so a common 4 cylinder engine would have 8 valves, 4 inlet, 4 exhaust.  Then along came the 12 valve engine, where there were two smaller inlet valves and one exhaust valve per cylinder.  This gave better inlet flow, particularly at higher engine revs, and from there it was a small step to add two smaller exhaust valves, giving 4 valves per cylinder!  Some exotic cars, such as Ferrari, and some really fast motorcycles, have 5 valves per cylinder, always 3 inlet and 2 exhaust.

     If you have the same car with a choice of 8 or 16 valve engine the 16valve is going to have a higher power output, and be ultimately faster...  But that is not the whole story, as the 8valve version  will certainly be more responsive at lower engine revs...  Take the VW Golf GTI with an 8valve engine, which was flexible and easy to drive, you could almost slow to a stop in 3rd gear, and just smoothly drive away from junctions or roundabouts, whereas in the same car, with a 16valve engine, there is not the large amount of torque available at low revs, so you would DEFINATELY have to change down to 2nd or even 1st gear to get moving again.

    Tuners generally take metal out of the cylinder head and fit larger inlet valves, and do some very clever work to make a good 8valve head get great top end power, without sacrificing too much torque at low revs.  remember, power gives you a high top speed, but torque is what hurls you up to a high speed coming out of a tight slow bend.
