Turbocharger on a two stroke 100cc

  • Turbocharger on a two stroke 100cc

    I'm in my final semester of mechanical engineering, and I chose to do my project based on turbocharger. By far, I'm very little known about the concept.
    I have a decade old kinetic zoom scooter, on which I'm planning to employ a turbocharger.
    Can anyone guide me through this?
    I've got two months in my hand, is it possible in this time?

      Actually I'm also looking for d same... But they say it's not possible to fix it for small cc engines but accordingly two stroke has more exhaustt power MAY B .... We must try out that...

        I think the direction you need to look into is not of a turbo charger, but that of a mechanical turbo which would be driven by crankshaft instead of the exhaust gasses. BTW You are from which college, Jondhale by any chance ?

          a sense of deja vu.... a very similar thread is going on on this community....
          anyways, first of all, is your kinetic zoom a 4 stroke or a 2 stroke? what i know of it, it is a 4 stroke. it will most probably be of no use to fit a turbocharger on the bike, the exhaust pressure is just not enough/ there is no ETC small enough for your requirements. what you need is a supercharger, which will run off the engine driveshaft. technically, there is more to it that just slapping on a supercharger to the scooter, but as a engineering project, it should suffice.

          on a different note, why don't you try to make a cng fuelled scooeter? that is much more relevant in indian scenario currently, plus the government might actually help u with funding, and most importantly, it will be easier to incorporate than a supercharger...
          think about it...

            I would say that it is very difficult and it might not even work at all for the reasons being that this Single Cylinder 100cc Engine has too little exhaust pressure to spool up the Turbo.You can improve it by a bit by making the fuel denser so the combustion is bigger,But then the already bad Fuel Efficiency will go waaaay down and the engine's RPM range too.I would say it just won't make enough Exhaust gas to spin the turbo wheel enough to get the impeller up to speed.
            As far as what I've learnt,Two strokes emit a blue smoke and are not as fuel efficient because of an inherit flaw that when the Air/fuel Mixture enters the Combustion Chamber,The exhaust port is wide open as the Piston is travelling down for the Air/Fuel Mixture to enter and then the port is closed by the Piston.As the port is open,A part of Fuel is lost as it escapes the chamber and goes wasted through the exhaust.But this is because of the Carburettor.With a turbo you would blow a lot of this 'escaped' fuel out of the exhaust pipe.Instead of working on a Turbo Charger,This is what I would recommend

            There is a technology known as Direct Fuel Injection or DFI,What it does,Is essentially FI on 4 Strokes.It sprays the Air/Fuel Mixture at a precise moment when the Piston closes the exhaust port,Meaning that all fuel is burnt and Oil is not pre-mixed with Petrol,That itself says much less Blue Smoke.This would also mean More Performance,Less Emissions,More Mileage.etc.Which also means,Slightly better backpressure.Meaning that the engine is so much better compared to a carubrettor and solves almost all the flays and inherit inefficiencies of the Two Stroke Engine.

            The only drawback is that it essentially kills what two strokes are known for - 'Simplicity'.Best of luck

              As an engineering student, an electric bike is not a practical bike, basis the ground up design required... an electric bike isn't just a battery and a motor slapped on... that's been done extensively... cng is actually practical as well as financially more viable

                Agreed.I wouldn't say they aren't 'practical'.They need the work from engineers like you.Because Fossil Fuels will cease to exist within the next 30 Years.All these combustion vehicles will be worthless.So only if we start now for bettering Electric Transport,We will be able to reach practicality way before when we need them.I mean,Let's be ready for the change

                    For a 100cc engine, you need a micro-sized turbo as the exhaust boost would not be sufficient to drive a bigger turbo.

                    What you can rather do is, design and make a turbo charger yourself by copying a bigger turbo. Fabrication won't be easy but 60 days is quite some time.

                    Do the math for the Exhaust pressure and turbo volume and make one.

                    I wish you luck for your project.
