Sealing Ring of Fuel Injector
As shown above, O-ring seal can ensure that
leakage will not occur when fuel injector works within
the range of -40°C -150°C (-40 -

Overvoltage Impact of Fuel Injector
The fuel injector can run at the voltage of 26V and
the working conditions of 100ms (pulse) and 200ms
(one cycle time) for 1 minute at most (run with oil). It
