Isuzu builds a V12? That is news to me.
what is the firing order of v12 12pd1
Firing order sl 450 v 12 engine
One firing order would be 1-7-5-11-3-9-6-12-2-8-4-10
What size engine?
1342
1-5-3-6-2-4
on a 1989 Isuzu pickup with a 2.6 same engine 12 degree b.t.d.c. at 900 rpm
the firing order
the firing order is 1-3-4-2
Same as it is with all inline six diesels (and most inline six engines, at that) - 1 - 5 - 3 - 6 - 2 - 4. Cat, Cummins, Detroit, Scania, Iveco, etc... all use the same firing order.
Timing would depend on the application of the motor. Some 998cc engine would have a higher compression than others and this would determine what the ignition timing should be. Normally it would be between 4 and 12 degrees BTDC. The firing order is easier. It's 1 - 3 -4 -2 Clylinder 1 is at the front (fan) end of the engine.
