Claims

[Scope of utility model registration request]

A variable bench lily that always controls the flow rate of air passing through the bench lily to be constant in response to the engine operating condition, and an air amount that outputs a change in the amount of air passing through the bench lily as an electrical signal by detecting the displacement of the variable bench lily. a sensor, a fuel amount sensor that outputs a change in fuel flow rate as an electrical signal by detecting a difference in fuel pressure before and after a main fuel jet for measuring fuel supplied to the engine; an air bleed control actuator that controls the air amount; an air amount that is determined by driving the air bleed control actuator based on the output signal of the air amount sensor; and a fuel amount that is determined based on the output signal of the fuel amount sensor. 1. An electronically controlled vaporizer characterized by comprising: a control circuit for setting the ratio to a preset constant value.
