The furture of 2-strokes?

Targ the hopeful /

Mercury Outboards has a two stroke wth a sealed crankcase as with a four stroke, and with the air-fuel mixture (without an oil component) inected into the cylinder, like fuel injection in four stroke engines. Black Twingle and another poster and I were discussing this as part of another topic earlier, but I thoght it might interest some of the technicians here.

I think an improvement could be made by injecting air during the power downstroke, the air completely pushing the exhaust gas out the exhaust port, and then, with the piston coming back up, inject fuel, the air and fuel would mix, and then at the top of the stroke the spark would ignite the mix. Seems simple to me .. no valves needed .. the crank and rings lubricated as in a conventional four stroke. ANyone want to invest a couple hundred thosand in development?

Count me in partner, where should I send the check?

Re: The furture of 2-strokes?

future of to stroke is like the rear wheel drive diapered when front wheel drive came then tuners where like hay this stuff rocks and gives u more power so i predict small engine tuners will want them back in like 10 years just saying

Re: The furture of 2-strokes?

To inject air, you'd need a valve. The point of port scavenging is to clear the exhaust gases with the charge coming up through the transfers. But it's not like you'll read this anyway. And I'm breaking my own 'please don't feed the troll' plea here.

Al Gore and his hippie friends don't want you to have a 2 stroke. Look for the air-cooled big bikes to go extinct, too. Liquid cooled runs cleaner. No more potato-potato sounding hogs. The dreaded VROD motor will be the standard mill shortly.
