FA20E and FA20F Subaru Engines

The FA20E and FA20F engines have a cast aluminium alloy cylinder head with chaindriven double overhead camshafts per cylinder bank. The four valves per cylinder – two intake and two exhaust – were actuated by roller rocker arms which had builtin needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms.

How to use MG811 Sensors Arduino Forum

May 06, 2021· Hi. I got the sensor MG811 that senses carbon dioxide, you can see an image of the sensor here I googled to use that sensor properly but i have doubts about the wiring with arduino and the proper way to calibrating. So, i got think i can got the data from AOUT pin, but i really don''t know if i can use the 5V pin from arduino to connect in vdd or i need another source (around 12V).

CO2 Monitoring with K30 Sensor Arduino Project Hub

Jun 20, 2017· I tried a number of analog CO2 sensors for that project, but I ran into calibration issues until I got a K30 CO2 module. This is a NDIR, digital, autocalibrating sensor, so it''s pretty easy to use. I am now starting a new open source project, this time using Arduino. I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino.
