Structure and working principle of fuel injector
The fuel injector location:
The intake manifold, the fuel injector is connected with the fuel line, connected to the lower part of the intake manifold
Injector structure:
According to the structure of the nozzle, the injector can be divided into axial needle type and hole type two.
A) hole injector pintle injector) B
Injector mainly consists of filter, wiring harness connector, electromagnetic coil, back spring, an armature and valve etc. composition, needle and the armature are made into a whole. The lower part of the needle valve pintle injector needle into the nozzle axis.
injector with hole nozzle
- features:
(1) the position and direction of nozzle and combustion chamber shape to adapt, to ensure that the oil vapor in the spherical combustion chamber connected to the jet wall.
(2) 11 high. ,
(3) the injector head hole is small, slender, the processing precision of business.
Effect of injector:
The O engine to provide the atomized fuel amount
