Now that I have generally covered the task at hand - ensuring that our engine and muffler will work together - I can finally start covering how to test that they work together.
When I last
mentioned the testing challenge of validating the engine output can always we
handled by the muffer, I mentioned 2 different test methods we could employ.
The first was an
automated test, running on a computer, which would compare the data sheet of
the engine to the data sheet of the muffler.
Specifically, it would look at the volume and pressure output of the engine and validate that all these numbers
were less than the maximum capacity of the muffler. If we assume that we can examine the data
sheets and that they are up to date then this is a terrific solution. Once we alter the document, we find out
instantly if the numbers will work for us.
If we were sitting around a design room, we could quickly look at
multiple different engine and muffler combinations and rule out sets that
obviously would not work. No need to
weld the engine into place or anything heavy like that. This type of check can prevent errors down
the road (so to speak), is relatively cheap to implement and gives very speedy
feedback.
This is a solution I
would push to implement to help with this problem.
Since I am a tester
by nature, though, this is not the only check I would want to use. We've all heard the old sayings of not
putting all our eggs in one basket and I would also want a backup system in
place to help me understand the operation of the engine and muffler system.
More on that next
time!
