Are Snowmobiles Two Stroke?
Millions of people enjoy snowmobiling during winter because of its thrilling experience. Early snowmobiles relied on 2-stroke engines, but 4-stroke engines became more common in the 2000s. Many manufacturers prefer them because of their powerful nature compared to their counterparts. When choosing a snow vehicle, it’s essential to consider the engine type you want.
Understanding Engine Types
The two-stroke and four-stroke engines work on a similar basic principle but operate differently. The smaller engine completes a power cycle in two piston strokes: the compression and combustion strokes. The engine’s moving parts are lubricated with a fuel and oil mixture.
The much bigger engine completes a power cycle in four piston strokes. These are the intake, compression, combustion, and exhaust stroke. 4-stroke snowmobiles have a separate lubrication system in their engines and don’t require mixing with fuel. This engine requires two crankshaft revolutions, where the first revolution draws the fuel-air mixture into the combustion chamber and ignites to produce power in the second revolution.
The Truth About Snowmobile Engines
Traditional snowmobiles were lighter and generated more power about their size compared to four-stroke engines. Their performance capabilities and engine simplicity made them ideal for snow navigation activities. They also offer a high-power-to-weight ratio, easier manoeuvrability, and are easier to start in the cold.
The shift towards four-stroke engines in recent years has primarily resulted from strict emission regulations and environmental concerns. These engines are environmentally friendly due to their quieter engines and near-complete combustion. The cost of purchasing snow vehicles with this engine is much higher, but they last longer and are more fuel efficient.
What Brands Offer 2-Stroke Snowmobiles?
When it comes to snowmobiles, several brands are offering unique features and various types of engines. Some popular brands include:
Polaris
This well-known brand offers double and four-stroke engines for different performance needs. One of their engines is the Liberty, known for high horsepower output and efficient power delivery. The engines feature advanced technologies like fuel injection to ensure optimal performance in varying weather conditions.
Additionally, the brand offers the Cleanfire engine, which prioritizes fuel economy and emissions reduction. The low gas mileage provides longer rides on a full tank. The engine features advanced technologies like EFI and turbocharging to enhance performance.
Yamaha
This prominent snow vehicle industry player is known for reliable and high-performance machines. Its two-stroke engines, such as the Genesis, deliver impressive acceleration and horsepower. This engine is favoured by riders who prioritize power and responsiveness. In addition to the smaller engine, the company offers a larger engine known as the Genesis Turbo, perfect for riders who desire power and better fuel consumption.
Ski-Doo
The brand’s two-stroke engines utilize Rotax technology to balance power and weight. These engines are available in single-cylinder and multi-cylinder designs to deliver impressive power output. They are often reliable in extreme conditions.
