Micro SUPERCHARGER on the TWIN Cylinder 4 Stroke Engine! - First impressions

  • čas přidán 1. 01. 2021
  • While I'm waiting for parts to arrive for the 4 cylinder 1/6 rc car, I decided to install my micro supercharger that I made almost 2 years ago. Of course I didn't have any expectations as in order to produce usable boost, it would need to spin at hundeds of thousands of rpm. Nevertheless, I tried with a rather small pulley (I could make a larger one but don't have a belt for that) and I got an engine that san't running very well. The dual carburetors don't help either. My plans are on the end of the video. Anyhing you can suggest is much appreciated.

  • @MrGrimCarnage
    @MrGrimCarnage Před 3 lety +135

    I was watching the smoke coming out of the exhaust when you were revving it, when it gets to the higher RPM, the smoke decreases significantly, indicating a lean condition. I've raced nitro buggies for many years and this is one of the traits that I watch for during operation, to determine if the tune is correct.
    I couldn't tell if the carbs on this engine have a low speed and high speed needle, but you are definitely running out of fuel under full throttle, when the engine revs up.
    You can try richening both needles 1/2 to 1 full turn, and see if that helps....if there are no low speed needles, then it may become too rich to idle properly. The pull through carb that you showed at the end should alleviate the problem, assuming that it's large enough for this engine.

    • @evansallee603
      @evansallee603 Před 3 lety +2

      I would agree with you! The carb adjustments make a big difference. I would also recommend if possible adjusting the ignition timing. This is because under boost the fuel air mixture in the engine burn quicker which could be potentially fighting the piston downward before it hits top dead center.

    • @ronbradshaw7404
      @ronbradshaw7404 Před 3 lety +1

      You may be right. There is the fuel pressure entering the carb too, HAS to be over the total boost pressure otherwise, fuel starvation will occur...

    • @ravensfan7986
      @ravensfan7986 Před 3 lety

      I was thinking the same thing since I know that with all that extra air getting into the engine you need to compensate by adding more fuel. If he was using the same carb as before that could be an issue if the jets aren't large enough

      @TestECull Před 3 lety +1

      They do have LSN adjustments....standard TN carbs...but the problem is more that he's running them blow-through than it is anything else. No amount of carb twiddling is ever going to get it to run right; these carbs just can not operate properly under boost conditions.

    Would it be an idea to put the carburators before the supercharger? That way the supercharger "sucks" the air/fuel mixture through the carburator, so you won't need to worry about backpressure etc.

    • @random123name1
      @random123name1 Před 3 lety +9

      As he said, the mixture leaning out is probably the result of the current carb setup. Whenever the supercharger delivers any kind of boost, only in high speeds, the pressure will reduce the fuel flow. And this is highly unlinear, exhaust backpressure could work but is hard to adjust. The only quick solution is carbs upstream of the charger.

      With blow through you Need to add the Boost on the fuel pressure plus 0.3bar, there are special valves for it for real Cars. Problem will be finding them in this size.

    You may want to add a pressure tap before and after the carb to measure static pressure. It's pretty easy to use some clear tubing to make a water monometer to operate at those pressures. You can do differential pressure too with that setup. Might help you determine boost issues at different RPM.

    For power readings there are two options, 1st you could use a brake that can rotate around its axis and use a load cell or other scale to keep it from rotating the force from the load cell or scale can then be multiplied by the distance to the axis to get the torque. 2nd option is using the engine to rev up a flywheel with a known inertia. Measuring how fast the flywheel accelerates can then be calculated to the power being put in to the flywheel

    Detroit diesel was at this step in the 50s. They addressed it by adding a turbo that was able to compliment the mechanical compression of the sc at increased exhaust pressures. The result was a increased performance across the board, but was later proved redundant. If your able, the history and evolution of the m113 and its variants would interest you. On a side note, I was there to see the changes and what was necessary to get the cummins triple nickle to over 600 hp, fielded in the m2/3, m3a3 variants back in 2001. Those modifications were only able because of the steps your taking. This is Awesome, rock on!

    Hi, awesome work! In order to measure power output, i would suggest driving a generator (permanent magnet dc motor). This allows to test the engine with a variable load, and to really measure net power output (volts x amps).

      This is my first through as well. Just need to properly calculate the losses in the diodes and in the motor. Then again if it is just A/B comparisons maybe the absolute power produced is not as important as relative difference. In other words have the changes made increased or reduced power output.

      In order for that to work, you'd need 2 check valves with very low forward pressure. One tied into exhaust and one tied into the intake and y'd into the tank. The intake wont provide pressure at idle like exhaust will, and if the sc were to work, the exhaust wont provide the pressure that the boost can. Still sounds like irratic tank pressure to me tho.

    Impressive machining! I think you may need an electric pump and a regulator that senses intake pressure/vacuum in order to maintain proper mixture throughout the rpm range. It seems to be leaning out on top end despite the pressure tap off of the exhaust. Either that or a draw-thru system, and use a single larger carb on the supercharger inlet.😉👍
