('93-'01) the sequenceof a 4 banger

WillReckXhop · 04-29-2001, 11:48 AM

alright i did a serch for about 15 minutes couldnt find anything. This might be a very newbie question but was just wondering if this is how an engine works for an inline 4.

cylinder1
compressed and about to ignite
cylinder2
sucking the air fuel mixture in
cylinder3
just ignited and full of exhaust gas
cylinder4
pushing gases out

if this is how an inline 4 works was just curious as to how an inline 6 would work or like the acura vigor an inline 5? very sorry if this has been talked about many of times.
thanks
peace

The firing order of a typical in-line four is 1-3-4-2, so add that to your four-stroke sequence and you have the complete order of activities

.

For a straight six the firing order is something like 1-3-5-6-2-2. A V12 is typically the same as the six, but bank A follows bank B: A1-B1-A3-B3-A5-B5 and so on.

Actually these are BMW firing orders but they are typical of inline engines. For vees (including boxers) it might be different; I would imagine a V8 to fire like two 4-cylinder engines, and a flat-four to fire like two 2-cylinder engines.

They all can vary...but I'm guessing they don't. Most engines will say on them somewhere what their firing order is.
