Embodiment Construction

[0041] as attached figure 1 and figure 2 As shown, a throttle valve flow test device includes a test bench, and the test bench is equipped with:

[0042] The negative pressure generator 16 is connected with the throttle valve to be tested through the flow sensor through the pipeline;

[0043] The throttle valve body fixing device 6 is used to relatively fix the throttle valve to be tested and the test bench;

[0044] The flow calibration system includes two calibrated flow blocks, the large and the small, and the flow calibration system calibrates the test system through the two calibrated flow blocks;

[0045] The control unit 15 has at least two signal input terminals and at least one signal output terminal, wherein at least one signal input terminal is signally connected to the flow sensor, and the other signal input terminal is signally connected to the test port on the throttle valve to be tested ; At least one signal output terminal is signal-connected to the negativ...

Abstract

The invention discloses a throttle valve flow test device and a test method thereof. The device comprises a test bench; the test bench is provided with a negative pressure generator, a throttle valvebody fixing device, a flow calibration system, a control unit, a computer, an information input device and a power source; the negative pressure generator is connected with a throttle valve to be tested through a pipeline; the throttle valve body fixing device is used for relatively fixing the throttle valve to be tested and the test bench; the control unit is provided with at least two signal input ends and at least one signal output end, wherein at least one of the signal input ends is in signal connection with a flow sensor, the other signal input end is in signal connection with to the test port signal of the throttle valve to be tested, and the at least one signal output end is in signal connection with the negative pressure generator; the computer exchanges information with the control unit; the computer displays flow calibration information through a display screen; the information input device is connected with the computer; and the power source supplies power to the control unit and the computer. With the throttle valve flow test device and the test method thereof of the invention adopted, corresponding relationships between the opening degrees of the valve block of the throttle valve and air-fuel ratios can be quickly defined, and it can be ensured that an engine can reach an optimal air-fuel ratio under different loads.

Description

technical field [0001] The invention relates to a throttle valve qualification detection, in particular to a throttle valve flow testing device and a testing method thereof. Background technique [0002] The throttle body is a key component of the EFI engine, which has the function of adjusting the air-fuel ratio of the engine. [0003] The engine ECU controls the air-fuel ratio by controlling the opening of the valve plate on the throttle body, so the ECU is required to preset the functional relationship between the engine air-fuel ratio and the throttle body valve plate. [0004] The throttle body flow test device is a device used to define the relationship between the air-fuel ratio and the throttle body valve plate and to test the flow rate of the throttle body. The traditional throttle body flow test and calibration system are separated, the test time is long, the efficiency is low, and the equipment integration is low. Contents of the invention [0005] The purpose...
