2.10.2 Description and Operation
2.10.2.1 Description and Operation

This vehicle uses DLI ignition system igniting two cylinders at
the  same  time.  The  ignition  voltage  is  sent  directly  from  the
ignition coil to the Spark Plug. Main system components are
ECM, two ignition coils, high voltage damping line, Spark Plug,
crankshaft  position  sensor,  camshaft  position  sensor,  knock
sensor etc.. This Ignition system is known as the direct ignition
type. Cylinder No.1 is paired with Cylinder No.4 and Cylinder
No.2  is  paired  with  Cylinder  No.3.  When  ECM  triggers  the
ignition coil to ignite, spark occurs in both cylinders at the same
time. At this time one cylinder is in compression stroke and the
other  is  in  exhaust  stroke.  For  the  cylinder  in  the  exhaust
stroke, because the cylinder pressure is low, the temperature
is high, the spark plug only requires minimal energy to break
ignition  voltage  gap.  It  is  an  invalid  ignition,  the  remaining
energy  is  used  by  the  spark  plug  in  the  compression  stroke
cylinder.

As a result of using DLI Ignition System, ECM controls the best
ignition timing based on a variety of load conditions, so that the
engine  output  power,  acceleration,  economy  and  emission
performance  have  reached  the  ideal  situations.  The  ignition
system voltage does not decrease as the speed increases. In
the absence of mechanical components, there is mechanical
error.

The ignition coil can not be repaired and it must be replaced as
an assembly.
