The World’s Most Pissed Off One Cylinder Engine Is Turbocharged AND Packs A Screw Blower!

First thing we have to do here is tell you that the audio in the video is kinda of sucky. That’s not a deal breaker for us though because it is good enough to hear this single cylinder engine punishing the atmosphere with noise and we also get a look at the mean little bastard bolted into the front of a mini-pulling tractor. We’re not sure what class this combo runs in or what the rules of said class are, but we want to see this tractor get to work. Why? Volvo diagnostic software download. Did you miss the part about this being a once cylinder engine with both a Kenne Bell screw blower AND a healthy sized Garrett turbo on it?!

Single-Cylinder Turbo This research is aimed at developing a novel method for turbocharging single-cylinder four-stroke internal combustion engines to create a more compact, fuel efficient and lower cost power source for small-scale farmers in India. Starting at the cylinder head — we don’t normally think of the actual exhaust port in the head as a part of the exhaust system — but nonetheless this is where it all begins. Understanding a little about cylinder head intake and exhaust runner design will help visualize what is. Turbocharging is not conventionally used with single cylinder engines because of the timing mismatch between when the turbo is powered, during the exhaust stroke, and when it can deliver air to the cylinder, during the intake stroke. In a traditional single-scroll turbo manifold, the exhaust pressure from cylinder 1 will interfere with cylinder 2 pulling in fresh air since both exhaust valves are temporarily open, reducing how.

Somewhere under all of the awesome piled onto it, is a 150ci flathead engine. We have to imagine that the block and rotating assembly are all 100% custom built because as we’re sitting here typing this there’s nothing coming into our minds that exists in the world as a stock 150ci one lunger. We’ll need your help in learning what class this machine fits into so we can try to dig up videos of the tractor actually hooked to a sled and flinging dirt halfway to the moon. We’re reaching out to the people that posted the video to see if the combo has ever been run on a dyno or anything. We have run angry v-twin pulling engines and even some single cylinder dyno video before but we’ve never encountered one like this. The induction system alone looks epic in this quickie cell-phone video!

Your mission if you choose to accept it is to watch this video and then tell us what the hell we’re looking at. Oh, we’re going to run outside and size up our lawn tractor for how to mount the blower as well. DO WANT!

My invention is a method for turbocharging single cylinder internal combustion engines. This technology makes small engines cleaner, more powerful, lighter, more fuel efficient, and lower cost. With new emissions standards coming online, companies are having difficulties keeping the costs of their engines down. This is especially a problem for developing nations where single cylinder four stroke engines power small vehicles, farm equipment, and generators. Turbocharged engines have better fuel economy, cost efficiency, and power density than an equivalently sized, naturally aspirated engine. Most multi-cylinder diesel engines are turbocharged for these reasons. However, due to the timing mismatch between the exhaust stroke, when the turbocharger is powered, and the intake stroke, when the engine intakes air, turbocharging is not used in commercial single cylinder engines. Single cylinder engines are ubiquitous in developing world off grid power applications such as tractors, small vehicles, generators, and water pumps due to their low cost. Turbocharging these engines could give users a lower cost and more fuel-efficient engine. The proposed solution is to add an air capacitor, in the form of a large volume intake manifold, in between the turbocharger compressor and the engine intake to smooth out the flow.

The theoretical feasibility of the air capacitor was analyzed, focusing on fill time, optimal volume, density gain that the system can achieve, and thermal effects due to adiabatic compression of the intake air. Computational techniques were used to determine that the system is feasible. It was found that the system is feasible from a cost perspective, since adding a turbocharger is expected to be approximately 20% of the cost of adding a second cylinder (doubling the power). This means that even in the worst-case heat transfer scenario, turbocharging is half the cost of adding a second cylinder per unit power gained.

An initial prototype was built and an experiment was conducted where it was found that peak power output increases with manifold size, increasing by as much as twenty nine percent with the largest sized manifold (approximately seven times engine volume). This is a significant increase in power and shows that turbocharging a four-stroke, single cylinder internal combustion engine is technologically and financially feasible.

An optimization model was built using Matlab, Simulink, and Ricardo Wave (an engine modeling software). The model optimizes the air capacitor and engine parameters around fuel economy, power, emissions, and air flow using a simulated annealing optimization algorithm. From this analysis I found that I can reduce emissions by 2-5%, improve fuel economy by 3-5% and increase power by 30-35% at the same time.

Using this information, a more advanced prototype and experiment were developed. Through the experiment it was found that the air capacitor turbocharging system can improve emissions, fuel economy, power, and transient response characteristics. This project will have a real world impact; it will give farmers a tool to make them more productive, reduce emissions from small diesel engines, and lower the cost of small devices that are powered by small diesel engines.
