How does fuel injection work on a snowmobile? (video)

Is fuel injection better than carburetion?

While the carburetor may have been around for over a century, fuel injection is a clearly superior alternative, delivering better power, fuel economy and lower emissions. via

When did snowmobiles become fuel injected?

Fuel Injection has been around in the snowmobile industry since the 90s. It is now commonplace on both four-stroke and two-stroke engines and is much more reliable and more efficient in today's market. via

Are new snowmobiles fuel injected?

Yes, it's safe to say that all new snowmobiles are fuel injected. via

What is the difference between E-TEC and EFI?

The EFI will be slightly louder at idle than the E-TEC but not really anywhere else and a bit smokier and smellier. It'll be snappy down low but weak up high. via

What does E-TEC mean on a snowmobile? (video)

What makes more power carburetor or EFI?

Warren Johnson: Properly tuned, carburetors make more peak power than EFI in a Pro Stock engine. A carb's pressure differential atomizes the gas a lot better than spraying fuel through an orifice. But EFI has a broader powerband and superior cylinder-to-cylinder fuel distribution. via

Do 2-stroke engines have fuel injection?

The 2-Stroke Of Tomorrow Is Evolving

All designs scavenge the cylinders only with air, incorporate some means of varying the exhaust timing, include a multiple-chamber cylinder head and utilize air-assisted fuel injection. via

Is Ski-Doo ETEC fuel injected?

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. via

When did Skidoo go EFI?

1991. - Polaris releases the 1991 Indy 650 RXL EFI, which was the first snowmobile from an OEM to feature fuel injection. via

When did Yamaha start fuel injection on snowmobiles?

Eventually, the know-how gained in the development of this engine would form the base for subsequent development of the 3-cylinder and 2-cylinder snowmobile engines. This 4-cylinder engine underwent its next evolution in 2006 for the Apex model. The new engine gained fuel injection and a much lighter crankshaft design. via

What is Polaris Cleanfire injection?

The Polaris Cleanfire relies on Semi-Direct Injection (SDI) technology that means fuel is injected not directly into the engine's crankcase like a conventional EFI 2-stroke, but rather, into the transfer port. via

How much horsepower does a Ski-Doo 600 EFI have?

With the new 85-horsepower 600 EFI 2-stroke engine from Rotax, Ski-Doo brings advanced electronic fuel injection technology to entry-level sleds. via

What's the difference between ETEC and PTEC?

Etec: can run upside down, smoke less,crisper throttle response, uses less oil, and summerize itself. Ptek: carb, can not run upside down, slower throttle response, smokes alot more does not summerize itself... lol but it seems to work for me 3100 miles mountian riding. via

What is good compression for a 800 ETEC?

130 is still fine, I'd be more concerned if your below 120. via

What year did the ETEC come out?

When Did Ski-Doo Switch To Etec? The company first released the E-TEC technology in its Evinrude outboard engines in 2003. It was then nominated and won the U.S. Clean Air Technology Efficiency Award. via

What is the fastest 2-stroke?

  • 5 Kawasaki KR500 – 120 HP.
  • 6 Yamaha TZ750 – 120 HP.
  • 7 1998 Bimota V Due Evolution – 110 HP.
  • 8 Suzuki RG500 – 95 HP.
  • 9 Yamaha RD500LC - 90 HP.
  • 10 Vins Duecinquanta – 80 HP. via topspeed.
  • 11 Kawasaki H2 Mach IV 750 – 74 HP. via cycleworld.
  • via

    What has more power a 2-stroke or 4 stroke?

    Because combustion takes place with each revolution of the crankshaft with a 2-stroke, this format puts out more power than a 4-stroke engine and the power has more instantaneous delivery. This are some reasons why 2-stroke engines have a long history of use on many different types of motorcycles. via
