What kind of engine is in a snowmobile?

Most modern snowmobiles are powered by either a four- or two-stroke internal combustion engine, with the exception of the Taiga TS2. Historically, snowmobiles have always used two-stroke engines because of their reduced complexity, weight and cost, compared to a similarly powered four-stroke.

Are snowmobile engines 2 or 4 stroke?

The two-stroke snowmobile engine is, mechanically, very simple, but how it breathes is rather complicated. A four-stroke engine separates the intake, compression, power and exhaust strokes with the use of poppet valves, but it only makes one power stroke every 720 degrees of rotation of the crankshaft.

Which skidoo engines are 4 stroke?

The snowmobiles Ski-Doo unveiled this week are the MX Z X 1200 4-TEC, the GTX Special Edition and the Expedition TUV. The MX Z 1200 is the first MX Z with a four-stroke engine. It features a traditional MX Z featuring position and feel.

Why are snowmobile engines so powerful?

The higher the displacement the more power the engine delivers. A 2-stroke engine produces more power than a 4-stroke power source with the same displacement. Fuel-injected snowmobile engines are more powerful than carbureted ones. Liquid-cooled snowmobiles are also much more powerful compared to fan-cooled models.

Are Rotax engines reliable?

Rotax engines are very strong & reliable wait & see those japanese bikes that we grew up with, we thought were amazing. Once they go to big power those bikes will fail. My cousin has a repair shop he rebuilds polaris engines 5 times a month the last couple years rotax engines ZERO.

What is high mileage on a 2-stroke snowmobile?

As a rule of thumb, 10,000 miles and above is considered to be high mileage on a snowmobile. Snowmobile engines last around 5,000-20,000+ miles, or even more depending on many factors like its type, how it’s used and maintenance. 2-stroke snowmobile engines usually need a “top end refresh” after around 5,000 miles.

When did the four stroke snowmobile engine come out?

The contemporary snowmobile came around the 1950s, when companies started producing more practical vehicles. In the 1960s, engines became smaller and lighter than ever before, which allowed for the design of the open-cockpit snowmobile. In later years, a four-stroke engine would come in addition to the traditional two-stroke.

What was the horsepower of a 1972 Skidoo snowmobile?

This engine was the largest available in any Skidoo snowmobile in 1972. The engine utilized a twin-cylinder, center-mounted design. Total piston displacement measured 771 cc, and the peak power output was 52 horsepower.

How big is a four stroke snowmobile engine?

One topic centered on two-stroke engines versus four-strokes. Ski-Doo expressed concerns about Yamaha’s exorcizing its two-strokes in favor of a series of four-stroke engines that would range from a 150-plus horsepower 998cc four-cylinder Apex down to an 80-horsepower 500cc Phazer.
