Chery Tiggo. Manual — part 220
Operation
The fuel delivery system is enabled when it reaches the following conditions:
• Turn the ignition switch ON (engine off), the fuel delivery system is enabled for 3-6 seconds.
• The Engine Control Module (ECM) receives a Crankshaft Position (CKP) sensor signal.
The fuel injectors are a solenoid-operated valve that meter fuel flow to each cylinder. The fuel injectors are opened
and closed constantly during engine operation. The amount of fuel is controlled by the length of time the fuel injector
is held open. The fuel injectors are powered by a 12 V source and are controlled through the ground side of the
circuit by the ECM.
The fuel pump operation is defined in the fuel system control strategy and is controlled by the ECM.
