Ski-Doo Unveils Direct Injected Snowmobile

2009 Ski-Doo MX Z TNT with E-TEC
Ski-Doo introduced Monday its new MX Z TNT snowmobile powered by the Rotax 600 H.O. E-TEC engine. The sled travels 21 miles per gallon of fuel and owners will likely only have to add injection oil once per season, Ski-Doo claims.

E-TEC direct injection represents the latest in fuel induction technology. Fuel is sprayed directly into the combustion chamber through the cylinder head where it has a complete burn to reduce emissions, boost economy and improve running quality.

The Valcourt, Quebec-based company says this is the cleanest two-stroke snowmobile engine available and it produces virtually no smoke or smell. The 415-pound sled retails for $9,549. Sneak into a dealership soon to check out a demo model before they’re gone.

Here are some facts about the new 2009 Ski-Doo MX Z TNT with E-TEC:

Fuel for E-TEC engines is shot directly into the combustion chamber through the cylinder head.
Aside from the E-TEC technology and the addition of 3D RAVE, the 600 H.O. engine is unchanged from earlier versions that were fed by the semi-direct injection system or carburetors. Output stays at roughly 120 hp.

3D RAVE allows for more precise exhaust valve timing and improved fuel economy and performance. An electronic oil pump is more accurate for better oil economy.

The engine features an automatic summerization function. At the push of a button, owners can prep the engine for summer storage in 2 minutes.

Its platinum-tipped spark plugs are warranted for 3 years or 6,600 miles.

The sled has aluminum HPG take-apart shocks all the way around and runs on minimum 87 octane fuel. Track lug height is 1 inch.
