The Following is a Email I recieved about "SAVING THE 2 STROKE!"
Hi Mike,
Firstly, I must declare that I own shares in OE(OEC.AX) company that has product targeting your concerns. I'm not a large shareholder, but a committed one. I believe in the technology. So do the "silent ones". If you know who I'm talking about, you'll understand. "They just don't want the story to get out" I've followed this stock for nearly 5 years now, and the truth has been "white-anted" at every turn....once would be ok, but they don't want the story to get out until they are compelled to "pay for it" by using it, in the way of royalties. Increasing royalties & a new CEO have meant customers are "coughing up" for engineering services. Some solace for you, and maybe something that will get your cylinders "fired-up" and telling all your mates!!! 2 Stroke is ALIVE & KICKING!!!!!!!!! (bikes are further down!!) "Direct Injection" of 2 strokes has delivered an outstanding result over the last 5-6 years. "NO SMOKE", and the fuel injection timing is exact and fuel droplets are less than 8 micron, the event being after "all ports"are closed. Although that depends on whether you want a certain ammount of ERG back into the cylinder. Tohatsu report a potential fuel ratio of 400:1, such is the accuracy of the ECM. All calculations by the ECM are done to ensure combustion every time......and this is PR from a licensee.
Mercurymarine makes 115hp to 250hp(6 models, soon to be outboard motors that are CARB rated to meet 2004-6 emissions standards and beyond, and they are 2 strokes with Orbital's "direct injection". Their site, which is very comprehensive.... www.orbeng.com But before you check out these sites, read the email right through, please.....(thanks)......... Tohatsu (Nissanmarine rebadge) engines are 40, 50, 70 90hp, and they intend bringing out 120 + 140hp outboards in the future.....you will like this one!!
It's all about 2 STROKE!!! Link.....NissanMarine.com
Bombardier, a huge US company, use this "clean 2 stroke technology" on 2 of their jetskis and 4 pleasure-boats.............just "search", and you will find it.
Snowmobiles need the "low weight & high power density".....as you can imagine, snow is soft, and a snowmobile can get bogged.......2 stroke has many willing "customers".
This is where it gets interesting...... Right now , Aprilia, Peugeot and Piaggio each use Orbital's DI on some of their 50cc 2 stroke scooters.
THE BEST PART IS!!! Fuel efficiency as good as 4 strokes can achieve!!!!!!! Emissions as good as, if not better than competing 4 strokes!!
The results have been proven for quite some years now...........
The next part could be.........."very interesting"..............
Aprilia tried using Orbital's direct injection on some of their racing bikes............notably the RS250. This was back in 1998. Their riders complained that when they came out of a bend and applied the power, they got thrown, or close to it, so immediate was the power of the 2 stroke. This was reported on the web at the time because they had interviews of their racing team after the event. Any reference was deleted from their site soon after......it was an embarrasment at the time.
Low weight, high power density, simplicity of construction, low production cost, and now competing fuel efficiency and emissions are set to propel 2 stroke back into the "spotlight". The "word" needs to be spread that 2 stroke isn't dead, and they need to listen to consumers.
"Ucal" a carburettor supplier based in India is 25% owned by Mikuni, one of the largest motorbike carby makers and suppliers, has just agreed to use Orbital's DI and have announced a new R&D facility costing several hundred million dollars. All can be verified on the net, from press releases & company reports.
Please post this on any message board you like.......only through word of mouth it will get out. Even the big auto companies, have worked extensively with Orbital on adapting their DI to the car market, using Orbital's "low pressure direct injection".
Finally............to look for the signs....... It's commonly known as "LPDI", "TLDI" or Optimax in the marine sector. "Ditech" or something similar for scooters, which are gaining strong market share.
The "ideal configuration" for any 2 or 4 stroke is for the injector to be sighted at 90 or as close to 90 degrees as possible. When this occurs, and "it has been done"(15 degrees off-set), there occurs "complete burn" which is their lowest starting point(F/E & emissions), but then they have had to deal with the structural integrity of the "head". Having to include an "extra hole for the injector is a "bummer" when it comes to structural integrity of the mass!! This has caused a major roadblock....and I mean major.....they don't like the medicine, so will delay as long as possible while they work out how it will be done. GM has come to the party, and have given a paper(available on Orbital's website).
I could go on and on, but more importantly the "good news" needs spreading, and I can't do it alone. Please help me and many "die-hards" who are also my friends, spread the word.
This unique fuel injection will revolutionise 2 stroke more than 4 stroke.....it levels the playing field!!!
Kind regards, Rob
AN OPEN LETTER!
I began riding motorcycles in the Mid 1970's. The Bikes were Japanese and 2 strokes. Suzuki,Kawasaki and Yamaha all had dirt and street machines in the 2 stroke catagory. Mike, my brother had several trail/street Suzuki TS 125's and Yamaha Dt125's that were a lot of fun and of course 2 stroke.My 1st Bike was a 1974 Suzuki Gt 380 3 cylinder 2 stroke. The 2nd was a Gt 550 3 cylinder 2 stroke. Both seemed reliable,fast and fun. I street raced other bikes in Des Moines,Iowa at the time (mid 70's)with theese machines and I always saw the 4 stroke Honda's or Harley's end up in my Mirror's. I had a ridding Buddy at the time and He had just bought a Yamaha SR500 bike. Beautiful Machine! We would ride around the Downtown loop go to Bars etc. This get's to the point-When we would stop and have a few beers at Sam's Downtown he could never get that thing fired up. With the 4 stroke single,You have to position the piston at the top of the stroke then there is the compression release and a leg numbing hard kick.Maybe the beer didn't help him,but 1 kick on my Suzuki or a push of the button and I was ready to grab gears! I would ussually have anouther beer while he kicked and cussed his new machine.I ussually had to push him to start him.Seemed to me to be a lot of work for a bike with less Horse Power than mine.I fell in Love with the the nice Mid Range power of the 2 stroke as opposed to the low end grunt of a 4 stroke.I enjoyed the sound and even the slight small puff of smoke from the back which reminded me everything was running well. I was Heartbroke when I found out that the new Clean Air Act was going to be the Demise of the 2 stroke Street Bike.I thought a few small motorcycles can't make any difference to this whole planet with it huge jet liners taking off and Factorys belching huge clouds.This is just a bunch of limp wristed Do good'rs that don't want people like me to have a good time on the bike of my choice.Didn' t they know that the 2 stroke has less moving parts and is easier for the public to work
on.Didn't they know about the powerband and how much I loved the mid range power. Had they never poped a wheelie or caught air coming over a rise at 80 mph on a country road early in the morning! HOW COULD THEY DO THIS TO ME! Now they are TRYING TO DO IT AGAIN! This time the target is all 2 stroke motorcycles.The front lines are the Enduro/trail 2 strokes but they also are trying to Kill the 2 stroke Motorcrosser's and Observed trials machines which are both competition only machines.The bill has already passed,but if enough people complain the EPA can delay or kill it.Do not let this happen! Contact the American Motorcycle Association/Your local dealers and your elected public servants.Start with the EPA! We will all be sorry if this happens. I am not happy about the AMA letting 4 stroke Motorcross 250's compete with 2 stroke 125's and Open Class 4 strokes riding against 250 2 strokes.They are trying to set us up for the kill! This is a way to gradually sneak the whole thing past us! I like to imagine what the 2 stroke Street Bike would be like if the modern technology was applied to the old Machines.I do not want to be wondering what the technolgy of the future could have done for my 2 stroke KTM Motorcrosser. Even if your a 4 stroke fan you should support a persons right to be able to have a choice in the matter.
as far as i can remember some years a go(mid 90`s)yamaha and ford got together and made a 1200cc 2 stroke engine and fitted it to some fiestas(cars)and gave them to the police to use.i was working for a ford dealer at the time and remember reading the press releases from ford,the tecnology they used seemed to be the same as what you are talking about.i dont know what came of the trial.also when damon hill was driving for arrows(f1 team)yamaha were the engine suppliers and i think there was talk about yamaha making a 3litre f1 engine that used the 2 stroke tecnology you were talking about.
I was a copper at Woking in Surrey early 90's the motors were 3 cylinder orbital motors but I think they were only 1000's.They were a very quick car much faster than the 1.6 escorts we used.
you might be right,i thought they were 1200 but it was a long time a go.i know they only used very very small amounts of 2 stroke oil per gallon of petrol.ive often wondered what happeded to the engine,as ford and yamaha never said no more about it.i dont think thay had any problems with it,as you said it was better than the 1.6 .
