Chinese Gasifier, JXQ-10

This is my journey in learning more about this Chinese gas producer, the JXQ-10A.


I got my JXQ-10 Gasifier in March of 2009 and had a hard time figuring out how to operate it.
The manual that came with it and the additional instructions that were part of the Ebay advertisement are both ambiguous in several places.
So I have learned a LOT on my own!

If you have recently gotten one of these machines, please do contact me for better instructions on how to get it running!!!

Here are links to what I have learned so far, Newest entry first:

July testing of Throttle Position Sensor and Oxygen Sensor on Generator

My Woodgas setup for 2014
My Current Woodgas System Setup

Over that last few months I have been working to understand how oxygen sensors work, so I could use one to monitior woodgas quality. At the same time, I observed that the generator's governor arm starts to move to open the throttle as the gas quality begins to deteriorate.
You see, in the past, I didn't realize that the gas quality was changing until the generator's governor had fully opened the throttle. By that time, it was too late to do anything about the gas quality before the generator had quit.
So, I thought that, if I could record these changes, I would have a way to react to the gas quality changes before the engine would die.

To accomplish that, I have added both a TPS (Throttle Position Sensor) and a narrow band Oyxgen Sensor to my generator.

Here you can see where the O2 Sensor (at the left, on the exhaust manifold) and the TPS (just above the governor arm) are located.

I have tested them and hooked them up to my Arduino Datalogger. Now I can see the reading on my LCD screen as well as recording their activity for future reference.
Woodgas O2 Sensor and Throttle Position Sensor test
You can see from the graph above that I now have two very useful readings. This graph was made while the generator was running on gasoline, just so I could concentrate on my new measurements.
The spikes that you see on the first half of the Oxygen Sensor graph are where the sensor is still getting heated up enough to begin producing accurate readings.
That's one reason why the more modern and MUCH more expensive O2 sensors are used in today's vehicles. (This one costs $15.00)

The grate plugged up pretty early, so I still have plenty of work to do, but the datalogger performed suberbly.
