How does the 2.0 liter kia engine ignition system work

Do all the sparkplugs fire at once and the injectors fire in sequence and if so how does the obd detect misfire on a cylinder?

No engine fires all spark plugs at one time.
Ever see an engine that has all pistons come up
at the same time,won't work designed like that
Injectors fire along with the plugs!!
You'll have to access a factory diagnostic
manual, if you want to know the misfire detection
strategy for your motor.
Could ask that question using Google or study
your motor on the internet

if it is a misfire, then that means it is probably the plug or the wire, change those first, if not then yes check the injector.

Sounds like the ignition wires,from the coilpack to the plug,or the coilpack itself

do a compression test. cylinder 3 could have a bad valve lifter or valve.kia sephia dont have push rods.it have a bucket type followers.a intake leak to that cylinder can also cause misfire problems.

The timing is fine, the egr valve is ok and the firing sequence is right on. Anything else it could be? And its a 4.0 liter engine if that helps.

Glowing manifold


The good thing is no fire. This happens when there is a severe misfire mainly with the ignition system. A blown head gasket cannot make this happen. The ignition fired out of sequence, a jumped timing belt will cause the vehicle timing to ****** so a timing belt is not the issue.Your solution and the fix is get a whole new distributor with a cap and rotor(the rotor internally broked) sparkplug wires new sparkplugs . A plugged catalytic will cause the car to have no power when acclerating , you didnt blow the engine a blown engine cannot cause a glowing manifold. only a good engine can

2004 KIA OPTIMA WON'T START AFTER SPARK PLUGS WERE CHANGES


HI. There are several areas of concern here. I will list them below. Check all areas stated in the list for faults.

Possible cuases:

1. Incorrect firing order set. On the 2.0, 2.4 and 2.7 engines. These engines are equipped with a distributor-less ignition system. This system incorporates a coil pack assembly, along with wire sets. In order for the assembly to fire correctly, the order of the wires must be set to the proper sequence. if not, the engine will not turn over, or start correctly. Make sure your firing order is correct, and make sure you have not placed a particular wire set into the wrong cylinder. I will post a picture of the correct firing order for your engine, below this list, shortly.


2. Incorrect spark plug gapping procedure. If the new spark plugs were gapped incorrectly, this will not allow for proper spark, thus, preventing optimal combustion, due to lack of fire. Check the spark plug gap using a wire gap gauge, and adjust if necessary. The gap should be 0.039-0.043 in. (1.0-1.1mm)

3. Failed coil pack assembly. This will be the worst case scenario. The coil pack supplies the necessary current that fuels each plug. The current is transferred, via wire sets.This will be the culprit if all the above areas are proven to be operational, and in good shape.

4. Failed wire sets. Replace the wire sets if faults are found at the connector at the ignition coil pack, or at the plug boot.



NOTE*
In order to provide the correct firing order for your engine, i will need the engine size and liter information, if possible. Please post this information, asap. Thanks..

Ignition Distributor location


There is no cap and rotor, as the vehicles igntion system is DIS (digital ignition system). The recommended tune-up on these motors require sparkplug and coil replacement. The coil type in this vehicle is COPs (coil over plugs). Usually moist and oxidation develope on the sparkplug chamber walls from faulty or worn coil boots. This causes the coil to short, they must be replaced at 75,000 miles at the same time the sparkplugs are replaced. Typical symtoms are: Vehicle stalls (restarts and runs normal), intermitted jerks/sputter while driving, misfires, rough idle, severe power loss. Hopefully this helps

I need to know the timing sequence for a 1998 Mercury Mystique 2 liter


ignition timing or valve timing?

ignition timing not setable.

info:
The ignition system consists of an ignition coil, spark plug wires and spark plugs.
The crankshaft position sensor signal is the basis for ignition timing calculations. The alternating voltage signal from the crankshaft position sensor is digitized by the powertrain control module. This digitized signal is then used to position the closing time of the primary circuit of the ignition coil.
Ignition angle is determined by the powertrain control module in response to engine operating conditions. Once ignition angle has been determined, the powertrain control module interrupts the current to the primary circuit of the ignition coil thus triggering the ignition spark which is supplied to the cylinders through the spark plug wires and spark plugs.
The ignition coils are triggered by the powertrain control module in pairs (cylinders 1 and 4 and cylinders 3 and 2) sending one ignition spark to the firing cylinder and one ignition spark to the corresponding cylinder on the exhaust stroke. This make sures that any unburnt fuel residues remaining in the cylinder on the exhaust stroke are re - ignited to provide cleaner exhaust emissions.
