TTEC4843:- LAMBDA TEST
TTEC4843 :- FUELS AND FUELS SYSTEM -PRACTICAL
Date:- 13/9/2011
In lambda test we ,learned to make the lambda tester. Which helps us to determine ,in a real time , if the air fuel ratio of combustion engine is rich or lean.
*Equipment used to make the tester :- Rectifier diodes, zener diodes , capacitors , 3 LEDS (GREEN,YELLOW,RED) , Jumper wires, and (RED, BLACK, GREEN) IC CHIP LM324.
*FIRSTLY WE HAVE TO TAKE A O2 SENSOR PCB BOARD ,AND INSTALL THE ALL ABOVE EQUIPMENT'S TO IT.
*THEN STEP BY STEP WE STARTING SOLDERING THE ABOVE EQUIPMENT'S ON THE PCB BOARD.
RESULT:-It shows us the working of the lambda tester in following way:
- shows us the rich & lean mixture with the help of LED's
- when it turns red it means, the mixture is rich.
- while the YELLOW LED is the signal going between the RED LED and the GREEN LED, where as the GREEN LED shows us the car is running on lean and is normal.
