    add or adjust backlash

    I'm looking at the feasibility of a lab set-up that would replicate two different systems to help develop our controls. The main issue I have is backlash between the motor under test and the dyne. It has a significant impact on our controls and must be accounted for in the lab rigs. Ideally it...

    diesel injector line speed pickup

    I am trying to find a simple way to record the rpm of a diesel engine with my data acquisition system. Unfortunately many of the machines I am working on do not have pre-taped holes in the bellhousing to sense the ring gear. And I don't want to resorting to installing hall effect sensors, light...

    resonant frequencies

    I have a general question regarding multiple order resonances. In my example I have a 3 cylinder engine running at 3000rpm, which gives me a firing frequency of 75Hz. When I check the sound recordings I have two big peaks at 75Hz and 150Hz, and a smaller peak at 225Hz. The big question is ---...

    Expansion chamber help

    I am trying to find info on an "expansion chamber" with smooth inlet and outlet. (think of a rat in a snake) Just about everything I can find on expansion chambers shows the classic squared cylinder. Is this meant as a high, low, or band pass filter? Any formulas/design info would be great. The...

    diesel fuel usage question

    I have been tossing this around for a couple of days. Let me know what you think/know. Assume you had two identical vehicles (mass, air resistance, tire size, ground clearance, cooling fan, radiator, thermal efficiency, etc) except one had a 6L v8 diesel and the other had a 4.5L v8 diesel...

    A2 vs 1045

    I need to replace some wear bars on a small wheel loader bucket and have some A2 and 1045 on hand. Which one will give me the best wear against concrete and sand? I have found some comparisons amongst various tool steels, but nothing to compare 10xx vs. tool steel. Thanks, ISZ.

    Diesel design paradigm - V6 & V8

    Just throwing out a question for discussion - Would it make sense to swap the intake and exhaust ports on a V6/V8 diesel engine? My thinking is that you put the turbo just above the flywheel and eliminate the convoluted exhaust plumbing. (see this picture for a relative location...

    MTS controller

    Does anyone have experience with an electro-hydraulic test system servo controller besides the MTS units? I have fairly simple needs except wanting the ability to run 2-4 channels as one station or several for maximum system utilization. This forces me into the FlexTest GT which is pretty...
