This is the world’s first 20 hp outboard motor designed with Lean Burn and Battery-Less Electronic Fuel Injection. The Suzuki EFI system operates Battery-Less, which is an industry first in this horse-power class. The DF20A is a smooth running “Next Generation” four stroke which delivers quick starts, great acceleration, awesome performance and superior fuel economy. Go Lean, Clean and Green, Go Suzuki!
A REVOLUTION IN INNOVATION
State-of-the-Art designs make the new DF20A the most technologically advanced portable outboard on the market today.
SUPERIOR FUEL ECONOMY / SUZUKI'S LEAN BURN CONTROL SYSTEM
First introduced on our DF90A/80A/70A, the Suzuki Lean Burn system is an intelligent system that monitors engine performance and operating conditions to predict fuel needs and deliver a leaner fuel mixture to the engine. The system delivers remarkable improvements in fuel economy over the engine’s entire operating range. This system is found on 14 Suzuki models from the DF9.9B up to the flagship DF300A, providing boaters with top-level fuel economy at all operating speeds.
NEW GENERATION FUEL INJECTION SYSTEM
These are the first outboards in their respective classes to offer fuel injection, and the DF20A/15A/9.9B engineering team did an incredible job designing the outboard without adding unneeded bulk or weight. All new components, including the inline high-pressure fuel pump, fuel cooler, vapor separator, fuel injectors, and a new throttle body, were designed as compact and lightweight as possible. The entire system was designed to fit in as little space as possible. The system operates battery-less, which is another industry first in the 14.7kW (20PS), 11.0kW (15PS) and 7.3kW (9.9PS) class. While fuel injection systems normally require battery power to deliver quicker starts, smoother running performance, and more acceleration in all conditions, Suzuki’s Battery-Less system does this all without the need of battery power.
LIGHT WEIGHT & COMPACT
The DF20A/15A’s lightest in class title is the result of a complete redesign of parts and components, striving to create the smallest and lightest parts possible without compromising integrity. Succeeding in this, our engineers have delivered an outboard that even when configured with a power tilt system still weighs less than the any other outboard in the 4-stroke 14.7kW (20PS) /11.0kW (15PS) class.
LEAN BURN
Lean Burn is a Suzuki patented technology that optimizes and reduces both fuel consumption and costs, delivering, under specific conditions, a better air/fuel ratio and greater fuel savings.
Fuel combustion needs a specific amount of air, this air/fuel ratio is called the stoichiometric ratio. Lean Burn system control changes this ratio to the benefit of lower consumption.
This creates a longer burn time and a more controlled explosion of the fuel, over the full downward stroke of the piston. This in turn means that there is power over the whole combustion stroke and subsequently a more efficient and complete burning of all the fuel available; leading to more power for less fuel and fewer emissions.
