US 2019/0048828 A1 · General aviation carburetor testing and analysis device

Abstract

A testing device for general aviation carburetors and fuel servos. The testing device is capable of replicating carburetor operating characteristics and using sensors to monitor and record the operating characteristics of both horizontal and vertical type carburetors, and compare the data received with predefined values. The testing device measures both test fluid and air flow through a carburetor. A moveable camera is placed within the throttle body of the carburetor being tested providing visual inspection of the fluid atomization with snap shot capability. The testing device also includes flow sensors to record the performance of the carburetor, providing automated data collection with memory storage. The device is fully portable with lockable caster wheels.

A portable analyzing device for carburetors and fuel servos used in general aviation comprising:
a housing supported by wheels;
an intake plenum secured to said housing, said intake plenum constructed and arranged to receive a carburetor to be analyzed;
a vacuum pump mounted in said housing, said vacuum pump capable of drawing an airstream through said intake plenum;
a junction member having a first end fluidly coupled to an outtake of said vacuum pump for receipt of the airstream, said junction member having a first piping element to direct a portion of the airstream to a vertical port extension and a second piping element directing a portion of the airstream to a horizontal port extension;
a port plug, said port plug insertable into said horizontal port extension when said vertical port extension is coupled to the carburetor or said port plug insertable into said vertical port extension when said horizontal port extension is coupled to the test carburetor;
a fluid pump coupled to a fluid tank and to said carburetor for transferring a test fluid from said fluid tank to a fluid inlet on said carburetor wherein the carburetor injects test fluid into the airstream;
a test fluid flow sensor to monitor the amount of fluid drawn from the tank;
a camera positioned within said intake plenum and insertable into said carburetor, said camera coupled to a display monitor allowing real time viewing of operational aspects of said carburetor;
a separator for removing test fluid drawn through said carburetor, said separator having returning test fluid to said fluid tank;
a computer system having a microprocessor and digital storage, said computer system recording the operating characteristics of said carburetor provide a test result of test fluid and airstream flow against predetermined operating characteristics assigned to said carburetor when operated in standard conditions.
