I was just thinking, what if you had custom cams made up and changed the injector/spark order via ems if you could make your engine fire in a 1-2-3-4 order instead of the normal firing order...

I wonder what affect it would have on power output if any and if it may reduce engine harmonics/vibrations because the powerstrokes would start at one end of the crank and work towards the transmission,Instead of going back and forth like the stock firing order does.
Im sure there is a very good reason that honda engineers have figured out a long time ago, I would just like to know what it is and if anyone has tried this before, what were the results?
I know, i know, too much time on my hands

 

Engines fire in a cross-pattern for a reason. You don't want to get a energy rhythm going to one side of the block. Its bad for wear and bad for harmonics.

 

worst thread ever...

**to the thread stater... learn how an engine works then ask.

Don't be mean. If he knew how an engine worked, then he wouldn't need to ask. Engine theory (ICE theory) is VERY complicated, and I'm sure 99.99% of us don't know even a quarter of what is involved.

The simple answer is what FairlightRacing said. It will alter the harmonics/balance of the engine. There is a lot of physics and dynamics involved with it. Just by mathematics alone, engineers would not even attempt to build something with a firing order that isn't balanced.

 

I know how an engine works, duh!
geez.

I was actually seroius about the harmonics and dynamics of having the power flow differently than the "normal firing order"
They say horizontally opposed engines have the least vibrations/harmonics. I guess thats why Porsche does this

If you look at different types of engines and see how they "fire", you can kinda see how the power flows through it...

I bet there are a few great engine builders that have thought about this at one time or another so dont flame me.
The energy rhythms makes sense, thanks for answering my question unlike gaysrious ...lol

 

it would take a lot more than an ems to change this. like a crankshaft. and camshafts. and a complete frontal lobotomy.
