FUEL INJECTOR CONSTRUCTION/OPERATION [LF]
E5U011413250N02
• Installed on the cylinder head.
• Mainly consists of a coil, spring, needle valve and ball.
• A signal is sent from the PCM causes excitation current to pass through the coil and thereby pull in the needle
valve. Since the ball that opens and closes the injection opening is integrated with the needle valve, it is pulled
together with the needle valve and fuel is injected.
• The amount of injection is determined by the
open time of the needle valve (equal to the
energization time of the coil).
