Inline 6 vs. V-6?

its a lack of a couple spaces. He was pretty clear.

I think that an inline 6, along with a V-12 (as it's basically two inline sixes sharing a shaft) is that it is perfectly balanced . . in an engine all the cylinders fire at different times, dictated by a number of things, I think in an I6 the timings work out so that every cylinder has a counterpart that is 180 degrees opposed, allowing perfect balance (and thus a smoother engine and probably a higher rev limit).
 
basic physics? that wont teach you ANYTHING about engine alignment etc.

on I5's there is a counterbalance on the shaft iirc allowing the engine to be better balanced.

you also have different ways of mounting the 6's, and then different ways of opposing the cyliders.

its allll way over basic physics, this is specific stuff most likely.

You're in for a rough ride if you think they teach you this in first year physics.

Of course they don't! I just need some background information for this stuff. Provided with basic fundamentals I love doing research on stuff, so long as it interests me..... dunno....I'm just a nerd I guess 😉.

even a minor physics background wont let you know anything about engines. they are so very complicated nowadays.
 
V6 smoothness often depends on the angle of the V, the firing order and the internal balancing, plus the size of the engine itslef may make a differnce

A V6 generally requires balance shafts. An I6 is perfectly harmonically balanced without needing anything extra.

The benefit to a V6 is that it is a more compact design, especially important for FWD applications where an I6 would usually be too long. Also, a V6 can use much of the same tooling that a V8 does, which simplifies the manufacturing process and keeps cost down. Larger I6 engines also suffer from problems with crankshaft and camshaft whip.

I'm going to disagree. While a basic physics background won't give him all the equations to express everything mathematically the essential concepts for the internal combustion engine are simple Newtonian physics with very little complexity. People get caught up in all the computer-controlled doo-dads to monitor everything and squeeze out that last fraction of performance, but it's only in the specifics of the "how" that things get complicated. The "why" is really quite simple.

like the 4.3L V6 GM has used forever in the Jimmy and Blazer. and other vehicles.

there's no harmonic balancer in inline's are there?
 
I've been through a year of physics and the closest thing remotely related to engines introduced is work and efficiency. You don't really need physics, just google.

i thought there were on I5's due to the fact that almost no matter what you cant have the pistons perfectly opposite each other to balance out each other
