Ariens EZ-Launch EFI Snow Blower Engine

The AX EZ-Launch engine with EFI applies modern automotive technology to snow removal products.

The AX® EZ-Launch EFI is a snow blower engine designed for the Ariens® line of Sno-Thro® products. EFI (electronic fuel injection) combines sophisticated computer controls with a high pressure fuel delivery system to provide optimum power and fuel efficiency. With the introduction of this new engine, Ariens is the first brand in the industry to apply modern automotive technology and offer an EFI solution for snow products.snow blower engine

The AX EZ-Launch EFI engine starts in two steps, versus six steps with a traditional carbureted engine. The user simply turns the key and pulls the recoil cord (or uses the electric start). The engine’s system uses an electronic governor, which virtually eliminates speed loss and delivers consistent throwing performance along with an ultra-quiet idle. The combination of electronic fuel injection and the e-governor also work together to use less fuel than traditional engine models.

Because the system is electronic, it automatically adjusts to the environment and can start in extreme weather, at high or low altitude, and can tackle any type of snow. With traditional engines, the machine can lose more than 10% of its power when encountering drifts or wet, heavy snow. However, the AX EZ-Launch EFI engine controls its speed automatically, and it won’t slow down when it encounters large piles of snow.

ariens-ez-launch-efiThe Ariens AX EZ-Launch EFI engine can be run in different modes: from full power to efficiency modes. While in efficiency mode, the engine runs quieter, uses less fuel, and runs at a slightly lower speed, making it a good option for early morning hours when others are sleeping. The power mode increases the engine’s output and provides the unit with more power to get through tough jobs. On average, an EFI powered Ariens launches 73 tons of snow per hour, or 15,000 shovelfuls.

The Ariens EFI system is completely sealed, helping to reduce maintenance costs. The system will not require adjusting as gas will not deteriorate if left in the engine. This allows users to store their machine without worry.

For 2016, the EFI snow blower engine will be offered on two models, the Deluxe 30 and the Platinum 24 SHO. Models will be available in late October 2016 at authorized Ariens dealers and Home Depot stores in the U.S. and Canada. Ariens dealers will exclusively carry the Platinum 24 SHO EFI model. The units come backed with a three-year consumer warranty.


  1. I just bought the deluxe 30″ efi snowblower and , so far, love it! Turn the key and you hear the fuel pump run, injector click, and one pull later, it’s running at the quiestest and smoothest idle, that I’ve ever heard a large single cylinder run. Twist the power control knob, not a typical throttle, to about 50 percent of full, and it keeps that engine power through varying depths and consistencies of snow. Turn on the handwarmers, and within a minute, you’ll notice them warming up. When you are walking behind it, as soon as you begin to turn it, it breaks its posi-traction and applies power to the outside wheel and turns with one hand operation. As soon as you straighten it back up, you’ll feel the posi engage, and off you go like nothing can stop you!
