I think... Hmm I'd have thought anyone with a car should know the basic's like that. Though I know a lot of my old mates were completely clueless about anything to do with engine's (i.e. no idea how it worked, just it did).

But good on you for reading through that and learning sometihng.

Though most of that is only for SOHC (Single over head cam engines) - and a lot of engine's these days (16v) are DOHC.

Also Not all cars have distributers these days either

The v6 animation was interesting - you can see why it gives such a smooth delivery of power, but not as big gains as a in line 6

You can get some SOHC 16v engine's where the 1 cam works both sets of valves...

Basically 16v's just mean there's 2 sets of valves either side of each cylinder.





24v engine's have 24 valves (still 4 valves per cylinder), but they have 6 cylinders. Thus 24.

Have a look at rotary engine's on that site - that'll make you go

just on the rotary page, very clever. What will the japs think of next.

Surely with all the technology floating around now within 10years you will be buying very very efficient engines 100-200mpg the norm.

I would even buy an electric car if they were cheap enough and you could get good distance on a full charge 200-300miles.

I hope not... I like Vrrmm Vrmmm.... not some whiney little electric motor.

and if your moaning about emissions, then think about all the jet planes - before you moan about cars, apparently a single plane crossing the atlantic is equiv of like 10 million cars going up and down the whole of the m1 (massive).

I find engines are less complicated than an electric motor. Magnetic Flux, wtf?

Ive done physics and know how motors work but to any normal person they woulnd't have the foggiest
