Suzuki Marine GB’s Clean and Green Marine Engines
Suzuki Marine GB is a major player in the outboard engine market. They offer a broad range of high-performance outboard engines suitable for virtually any application.
Range of Power
Their engines range in power from 2.5 to 350 horsepower, catering to all types of leisure craft and commercial vessels.
Advanced Technology
The engines are technically advanced, cleaner, and greener. This is due to Suzuki’s marine engines being developed specifically for use on the water. Incorporating features that are not used in other Suzuki products makes them stand out from the competition.
Lean Burn Technology
Mark Beeley, Head of Marine & ATV at Suzuki GB, spoke with Power Progress International and explained that they use patented Lean Burn technology to optimize fuel usage by adjusting the fuel/air mix, or stoichiometric ratio. This helps reduce fuel consumption and in turn cuts overall emissions.
The Lean Burn technology was originally used in Suzuki cars and was dropped because it cannot be used with a catalytic converter. However, it works well in marine engines, where the engine control unit interrogates the engine and adjusts the fuel/air mix to achieve the most efficient outcome. This patented tech helps to extend the number of opportunities to reduce fuel consumption.
Clean Ocean Project
Suzuki Marine GB is not only offering fuel-efficient and cleaner engines but also helps to clean up the oceans. They have been running a Clean Ocean Project for about 15 years, where every Suzuki operation around the world is obliged to take one day each year to help clean up a beach, removing all the rubbish. Even the shirts worn by the team at Seawork 2024 are made from recycled plastic.
New 3rd-generation four-stroke engines
Suzuki is now building up its range of new, third-generation four-stroke engines. The latest of these are the DF115 BG and DF140 BG, which use a fly-by-wire control system. These engines are the first to feature a microplastic collection device as standard, which is part of the Clean Ocean Project mentioned earlier.
Propeller Design
Unlike most engines, which have a single peak sweet spot where economy and power output are balanced for optimal fuel efficiency, the Lean Burn has a flat line. This helps to extend the number of opportunities to reduce fuel consumption. Suzuki has also developed a different propeller design which helps with overall balance. The engine block is moved forward, and a gear mechanism fitted in that space which supports an off-set driveshaft. This means that the transom supports more of the engine weight, helping with overall balance while reducing the lever effect.
New DF250 KURO
The latest marine engine launched by Suzuki GB is the DF250 KURO. The 4.0-litre 24 V V6 DF250AUNX features new electronic mapping, which has allowed peak engine speed to be increased from 5700 to 6000 rpm. In addition, reworked air intake louvres deliver more air to the engine, helping to cool the engine as it gains speed. Other changes include a redesigned lower unit that now incorporates design features taken from racing outboards to improve cruising performance and reduce cavitation.
The DF250AUNX uses the Suzuki drive-by-wire throttle system, auto trim, keyless start, and Lean Burn tech. It is a perfect example of the reliability and dependability that Suzuki Marine GB offers through their technology and innovation.
