Do-It-Yourself Turbocharger Turbojet
This is a run-up of my home built turbocharger turbojet engine. Long, but maybe of some interest to other engine builders. It is quite old now and dated somewhat and I now know far more about jet engines than I did then. Please go easy on me guys... It is my first video!
I would like to issue a challenge to all fellow Do it Yourself turbojet engine builders and brushless electric R/C park flyer hobbiests/manufacturers out there.
Please comment and discuss the feasibility of mounting a small "outrunner" style permanent magnet brushless electric motor to the compressor side of this and similar engines. I realize that shaft harmonics and bearing limitations will play a very significant role in whether or not such a motor/generator combination would hang together at 140000 RPM or more. Of course, associated power electronics with the ability to switch from starter motor to DC generator would need to be designed as well to efficiently (relatively speaking) produce electricity at these ultra high speeds.
Such a device would mimic some of the hybrid turbocharger or "electrically assisted turbochargers" that have been developed by Garrett and others in recent years. These have been designed, developed and built to reduce "turbo lag" and recover wasted energy in the form of electricity with the intention of supplementing the charging system in vehicles. They have not quite made it to market yet in any production vehicles that I know of. I am crossing my fingers!
A hybrid turbocharger in my opinion is the Holy Grail for DIY turbojet enthusiasts.
Once this exists as an off the shelf device, a whole world of potential uses opens up!
An inexpensive, simple, robust turbojet engine! Heat and electricity with only one moving part!
Imagine a tiny turbocharger based boiler in your basement that would heat your home, heat your domestic water AND charge your batteries in an off-grid or grid tied electrical system.
It would easily burn almost any conventional fuel including natural gas, propane, diesel, kerosene, waste oil, waste vegetable oil, bio-diesel, pellets, garbage and even wood logs as has been proven with the proof of concept device built by myself and Mark Nye at Nye Manufacturing and featured on The Discovery Channel's Daily Planet.
Your comments and discussions about how a PM motor generator could be adapted to this task are anticipated.
As promised, I am currently (slowly) working on a large afterburning VT-50 based engine (actually three of them) that will hopefully produce a combined two or three hundred pounds of thrust and be featured on Youtube soon.
I would like to run all three together in a stretched Quad ATV or mini dragster to take around to the car shows and make some noise. My concept for this engine will to both fuel and lubricate it with waste motor oil. Hopefully I will be able to offer construction plans and combustion chamber kits if it is successful and interest warrants it.
Thanks for looking! Good luck with your projects!
Varex Exhaust on an R33 GTS Skyline.
7" cannon Varex muffler with 4.5" tip and 2.5" catback on a non turbo R33 Skyline.
For those that don't know the Varex muffler is designed so that when open it gives off the full, loud volume you'd expect from a cannon. When closed however, it is quieter than a stock Excel, I am not exaggerating. It is controlled by a remote control that I had on my keyring.
Another thing to note is that the camera I used to film this is an $80 POS with the worlds worse microphone, it is also directly in front of the Exhaust pipe. This means the sound you hear is nothing like what it sounds like in real life. In real life the car had a nice, typical RB25 note, was a little drony at 100kph, but this was easily fixed by closing the muffler.
The point? Loud cars are great, but not all the time. With this muffler you can quieten it when you pull into your house at 3am so as not to piss the neighbours or your family off. You can close it as soon as you see cops, so they're less likely to EPA you. Hell, I was late to an outdoor wedding recently and thankfully didn't have to disturb the wedding with my obnoxiously loud Exhaust when I pulled up.
EcoBoost Technology - Animation
Ford Motor Company is introducing a new engine technology called EcoBoost that will deliver up to 20 percent better fuel economy on half a million Ford, Lincoln and Mercury vehicles annually in North America during the next five years.
The EcoBoost family of 4-cylinder and 6-cylinder engines features turbocharging and direct injection technology. Compared with more expensive hybrids and diesel engines, EcoBoost builds upon today's affordable gasoline engine and improves it, providing more customers with a way to improve fuel economy and emissions without compromising driving performance.
"EcoBoost is meaningful because it can be applied across a wide variety of engine types in a range of vehicles, from small cars to large trucks -- and it's affordable," said Derrick Kuzak, Ford's group vice president of Global Product Development.
"Compared with the current cost of diesel and hybrid technologies, customers can expect to recoup their initial investment in a 4-cylinder EcoBoost engine through fuel savings in approximately 30 months. A diesel will take an average of seven and one-half years, while the cost of a hybrid will take nearly 12 years to recoup -- given equivalent miles driven per year and fuel costs," he said.
Ford will introduce EcoBoost on the new Lincoln MKS flagship in 2009, followed by the Ford Flex and other vehicles. By 2013, Ford will have more than half a million EcoBoost-powered vehicles on the road annually in North America.
In 2009, Ford first will introduce EcoBoost on the Lincoln MKS featuring a 3.5-liter twin-turbocharged V-6. It will produce the power and torque of a V-8 engine with the fuel efficiency of a V-6. In fact, with an estimated 340-horsepower and more than 340 lb.-ft. of torque, the Lincoln MKS will be the most powerful and fuel-efficient all-wheel-drive luxury sedan in the market.
More With Less
EcoBoost's combination of direct injection and turbocharging mitigates the traditional disadvantages of downsizing and Boosting 4- and 6-cylinder engines, giving customers both superior performance as well as fuel economy.
With direct injection, fuel is injected into each cylinder of an engine in small, precise amounts. Compared to conventional port injection, direct injection produces a cooler, denser charge, delivering higher fuel economy and performance.
When combined with modern-day turbocharging -- which uses waste energy from the Exhaust gas to drive the turbine -- direct injection provides the best of both worlds: the responsiveness of a larger-displacement engine with fewer trips to the gas pump.
Ford's 3.5-liter EcoBoost V-6, for example, can deliver upwards of 340-plus lb.-ft. of torque across a wide engine range -- 2,000 to 5,000 rpm versus 270 to 310 lb.-ft of torque for a conventional naturally aspirated 4.6-liter V-8 over the same speed range. At the same time, this V-6 gives customers an approximate 2 mpg improvement and emits up to 15 percent fewer CO2 emissions to the environment.
Direct injection coupled with turbocharging allows for the downsizing of engines that deliver improved torque and performance. A small 4-cylinder EcoBoost engine has the capability of producing more torque than a larger 4-cylinder engine -- nearly an entire liter larger in displacement -- with better fuel efficiency.
The real-world fuel economy benefit is consistent no matter the drive cycle, meaning the engine is efficient in the city as well as on the highway -- unlike hybrids, which are most efficient in stop-and-go traffic. In addition, customers who tow and haul -- and have long turned to more expensive diesel powertrains for their superior towing capabilities -- can find the engine performance they need from an EcoBoost powertrain.
EcoBoost -- combined with multi-speed transmissions, advanced electric power steering, weight reductions and aerodynamic improvements -- is part of Ford Motor Company's strategy to deliver sustainable, quality vehicles that customers want and value. Additional hybrid offerings and diesel engines are planned for light-duty vehicles.
Longer term, Ford plans to remain aggressive in the development of plug-in hybrids and hydrogen fuel cell-powered vehicles.
"We know that what will make the biggest difference is applying the right technology on volume vehicles that customers really want and value and can afford," said Kuzak. "EcoBoost puts an affordable technology within reach for millions of customers, and Ford's systems approach adds up to a big idea that differentiates Ford's sustainability strategy in the market."
