06 - SQR484F ENGINE MANAGEMENT SYSTEM
Fuel Injector
Description
The fuel injector is located on the cylinder head near to intake valve, and the nozzle end is located directly
above the intake port.
Operation
The Engine Control Module (ECM) sends electric pulse to injector coil, forming magnetic field force. When
magnetic field force increases enough to overcome the resultant force from return spring pressure, needle
gravity and friction force, the needle begins to rise up and injector starts to inject fuel. The pressure of return
spring forces the needle to close again when injection pulse stops.
