Abstract
An easy calibration device of automobile air flow meter utilizes an air flow generation unit to generate the same amount of air flow in two symmetric branch tubes of T-form tube separately then executes calibration on standard automobile air flow meter and automobile air flow meter to be calibrated set separately in two branch tubes of T-form tube, an air flow regulation valve is used to control air flow amount in T-form tube.
Description
Technical field
The invention relates to a kind of simple automobile air flow meter checking device, be mainly used in performance test in the automobile air flow meter technical research or the automobile air flow meter Quality Detection in producing in batches.
Background technology
Automobile air flow meter is mainly used in measures engine institute amount of air drawn, and then is used for engine control system and determines burning condition, control air-fuel ratio, starting, igniting etc.Air inflow that engine computer then measures according to air mass flow and engine speed at that time come and the fuel feeding program that sets in advance relatively after, calculate required fuel delivery and relative injecting time.
Produce in batches for automobile air flow meter technical research or automobile air flow meter, verification is a committed step.And special-purpose usually automobile air flow meter calibration equipment price all compares costliness, therefore can cause research or produce the disposable input of testing cost in batches very high.
The invention provides a kind of simple automobile air flow meter checking device, simple, convenient, easy row can reduce automobile air flow meter calibration equipment cost greatly.
Summary of the invention
The invention provides a kind of simple automobile air flow meter checking device, this device mainly comprises:
(1) T type pipeline, pipe diameter is identical with the internal diameter of outer cover of automobile air flow meter to be verified.The ducted air-flow size of two symmetric part of matrix of this T type pipeline is identical.
(2) air-flows produce equipment, are connected on the T type pipeline main conduit, are used for producing the ducted air-flow of T type.
(3) gas flow modulation valves are used for controlling the air mass flow size in the T type pipeline.
(4) standard automobile air flowmeter and an automobile air flow meter to be verified are installed in respectively in two laterals of T type pipeline.
Because the air-flow size that air-flow generation equipment produces in two laterals of T type pipeline is identical, and a standard automobile air flowmeter and an automobile air flow meter to be verified are mounted respectively in these two laterals of T type pipeline, therefore can carry out check test to two automobile air flow meters easily.And,, can control the air mass flow size in the T type pipeline by the gas flow modulation valve.
Description of drawings
In claims of present patent application, pointed out theme of the present invention particularly, and clearly it has been proposed patent protection.Yet with reference to following detailed description and accompanying drawing, relevant structure that can better understand the present invention and implementation method with and purpose, feature and advantage.
Fig. 1 represents a kind of simple automobile air flow meter checking device synoptic diagram.
