<p>Hi Nicolo and Gasification Colleagues,</p>
<p>Nico would you please explain the definition of MP2 as it is not
a familiar abbreviation within my knowledge. <br>
</p>
<p>Monitoring engine oil contamination can be quite an interesting
activity using any type of fuel, and the basics are simple to
apply without resorting to special equipment. If you link to the
Fluidyne Archive <br>
</p>
<pre wrap=""><a class="moz-txt-link-freetext" href="http://www.fluidynenz.250x.com/">http://www.fluidynenz.250x.com/</a></pre>
<p>Scroll down to the Archive File: Producer Gas Engine Oil and
Soot, you can read more about how to do it. I also have a more
detailed write-up that we used to hand out to read the oil spot
blotters. If the interest is there, I will dig it out of the box
files and post it for those interested.</p>
<p>In regards to relying on the color of the oil as indication of
the amount of insolubles it contains, this is only relevant if the
pH Total Base Number (TBN) remains high. If the gas moisture
levels are masked by reheating the filtered gas, then that
moisture will rapidly deplete the pH and the oil will move into an
acid state. Two thirds of all engine wear is actually acid
erosion, not particle abrasion. If soot is being carried in
suspension, it will drop out to form sludge and the oil will look
perfectly clean. You can expect the oil to darken immediately
after oil changes, as the anti-oxidant additive heats and creates
the first darkening of the oil. Good quality Gas Engine Oil has a
high TBN, but then so does Diesel Engine Oil, so both are good for
producer gas applications.<br>
</p>
<p>The other effect of moisture in producer gas is that it slows
down the flame speed of combustion and gas continues to burn out
of the exhaust valves causing seat recession and CO emissions. <br>
</p>
<p>Hope this might be of interest.<br>
</p>
