Hi guys, after reading through a lot of useful info on here i decided to sign up to ask for some advice etc on my current project.
First off i know little about electronics but i am a very competent mechanical engineer and i specialised in building the ECU for our race car in uni. So i am no stranger to in depth electronics, i just don't understand them completely.
My project is to build a fuel injector test rig, allowing me to measure the flow through automotive fuel injectors.
My current design uses a 555 timer to generate a square wave signal with an amplitude of 12v and an adjustable frequency. to effectively vary the pulse width of the injectors to simulate different driving conditions so i can monitor and analyze the injector spray patterns at different RPM's.
However i quite fancy being able to digitally generate this signal and analyse the data graphically. I have NI Labview 8, and i have been told i would be able to hook up a USB interface with Labview to output the signal from the PC and hook it up to the injectors. Then by the use of a webcam i could monitor the flow through each injector into a graduated measuring cylinder and get labview to analyse and compare the flow of different injectors graphically on the computer.
Does this seem feasible to any of you guys? i think it would be a really cool project for me to do and would be a great help in any engine fuel injection development i wanted to do with my race bikes etc.
Cheers
