Introduction of fuel injectors
Injector is actually a simple solenoid valve, when the
electromagnetic coil power, the suction, the needle was sucked,
open the nozzle, the fuel needle through the needle head and the
nozzle between the ring gap high-speed jet , The formation of mist,
conducive to full combustion.
The nozzle itself is a normally closed valve (normally closed valve
means that when there is no input control signal, the valve has
been in the closed state; and normally open valve is when there is
no input control signal, the valve has been in the open state, by a
The valve needle to move up and down to control the opening and
closing of the valve.When the ECU issued a fuel injection
instructions, the voltage signal will flow through the nozzle of
the coil, a magnetic field to the valve needle to suck, so that the
valve is open so that the oil can The biggest advantage of the fuel
supply is the fuel supply control is very accurate, so that the
engine in any state can have the correct air-fuel ratio, not only
to keep the engine running smoothly, the exhaust can also meet the
environmental laws and regulations specification.
