A word from Suzuki engineers Hideto Nakamura Yukihiro Yoshikawa Hideto Nakamura (Development and Design Group) PRODUCT INFORMATION In charge of engine design and overall design coordinator. Suzuki Employee for 16 years. Career in company: PWC engine development, snowmobile engine development, outboard engine design I worked on development and design of the outboard motor with a focus on reducing the total weight of the outboard engine. When we were developing the outboard, we wanted to reduce weight so we looked not only at the large parts, but at the smallest of parts, component shapes, processes, even the materials as well. We also used combustion and ow analysis extensively to determine the optimum shape of each part so as to obtain the desired power output from the engine. The new DF20A/15A is extremely lightweight and produces power output from low rpm. I’m very satised with the results. Yukihiro Yoshikawa (Development and Design Group) Hiromichi Takewaki In charge of the design of electronics. Suzuki Employee for 15 years. Akinori Yamazaki Since the DF20A/15A is the smallest horsepower outboard to be equipped with fuel-injection, it was a challenge obtaining the same level of performance found in larger outboards while reducing the size of the parts. In regard to the ECM (Engine Control Module), we designed it to operate without a battery, and incorporated a variety of devices to improve fuel eciency so you can fully enjoy the benets of fuel injection. Akinori Yamazaki (Experiment Group) In charge of experimental development. Suzuki Employee for 8 years. When developing the DF20A/15A, we focused on the benets of a battery- free fuel injection system. Compared to an analog-type carburetor, a number of engine functions can be controlled electronically, startup performance is not inuenced by the operating environment, idle rpm is very stable, and by taking advantage of the lean burn system, it delivers superior fuel eciency. Compared to the simple structure of a carburetor, we completely rethought the layout of the fuel injection system, giving priority to the function of each part so that the resulting system was the same size and weight of a carburetor. Hiromichi Takewaki (Production Design Group) In charge of engine rigging. Suzuki Employee for 8 years. When we started developing the new DF20A/15A, we made a conscious decision to develop as compact and lightweight an outboard as possible. In particular, the new fuel injection system enabled us to reduce the size of the outboard, and the use of resins allowed us to reduce its overall weight. While incorporating fuel injection increased the number of parts compared to a carbureted system, through trial and error we could t everything into an engine cover that is nearly the same size as the previous outboard.
