TWO- STROKE ENGINES PRODUCE LOWER EMISSIONS THAN FOUR-STROKE ENGINES?


Attention environmentalists! The latest "talk of the town" is that some students from Colorado State University have developed a two-stroke engine that actually produces LESS emissions that its four-stroke counterpart. CSU students competing in the third annual Clean Snowmobile Challenge, sponsored by the Society of Automotive Engineers, grafted their idea from two sources: natural gas compressor engines and Ski-Doo personal watercraft.

The plan was to utilize the injection technology used by Ski-Doo and Australian company Orbital Engine Corporation, and present it in a more affordable format. While the Orbital system is expensive, the CSU students' design added only $500 in equipment to a standard snowmobile.

Using a direct fuel injection system, the CSU students were able to reduce carbon monoxide emissions by 99.4 percent and unburned hydrocarbons by 89 percent. Obviously, this presentation has enormous implications not only to the snowmobile industry (which has suffered attacks from a variety of environmental agencies over current two-stroke emissions), but also to the many areas of the world seeking to adapt these cleaner engines to the millions of two-stroke engines currently in use. What effect the CSU design will have in the "real world" remains to be seen.

Heck yeah, that would be awesome.  The power of a 2 stroke and the low emissions of a 4 stroke. The best of two worlds.

they'll get the 2 stroke emissions to where it should be, just for now the 4 stroke is a quick fix in the amount of production models at a certain level that the epa wants. just like the late 70's till the late 80's the car companies putting air pumps into the exhaust and the large end on tailpipes.

A glimmer of hope.  More like staring at the sun.  2 strokes are the way to go.  As far as im concerned even cars should be 2 stroke.  All the gas pumps have oil mixed with the gas so its just like a 4 stroke.

A two-stroke burns more efficiantly when ridden hard and fast.Maybe the 4 strokes should be touring machines as tourers tend to ride a little slower.If you ride a 2-stroke like that it wont burn as clean.Just my 2 cents
