Here’s a twist flying in the face of the commonly accepted belief 2-strokes are not environmentally clean. BRP, makers of Bombardier ATVs, Ski-Doo snowmobiles, Sea-Doo watercraft and Johnson and Evinrude outboard engines have been awarded the Clean Air Excellence Award from the US Environmental Protection Agency (EPA) this past April.
No, BRP didn’t receive the award for 4-stroke technology but for its Evinrude E-Tec 2-stroke outboard motors. The E-Tec Direct Injection system received the EPA’s coveted endorsement as a result of the system’s ability to achieve carbon monoxide emissions 30 to 50 times lower than a similar 4-stroke outboard. At idle, emissions can be as much as 100 times lower.
Could this signal the return of 2-stroke ATVs? Stay tuned.
