2013 SSANGYONG KORANDO Crankshaft

Components
Piston assembly contains piston, #1 ring, #2 ring, oil ring, piston pin and snap ring. The expansion energy
from engine is transferred to the crankshaft through connecting rod to convert the linear movement to
rotating energy.Overview

1. OVERVIEW
The ignition system is to supply high voltage generated from the ignition coil to the spark plug. The
G20DF engine is equipped with the independent type direct ignition system that the ignition coil is
installed in each cylinder.
The basic ignition timing in each cylinder is determined by the signals from camshaft position sensor and
crankshaft position sensor.
This ignition system controls the electronic ignition timing received from the engine ECU. To control the
ignition timing precisely, the ECU use the information below:
Engine load
Coolant temperature
Intake air temperature
Engine rpm
Camshaft position sensor (CPS)
Crankshaft position sensor (CKS) -
-
-
-
-
-
If the signal from the camshaft position sensor is not delivered to the engine ECU, the ignition coil and
fuel system cannot be operated.
