Downsizing of Fuel Injection Components for Small Motorcycles
Published November 17, 2015 by Society of Automotive Engineers of Japan in Japan
In recent years, more and more small motorcycles, such as scooters, are introducing Fuel Injection System (FI system) worldwide. As motorcycles have limited component spaces, it is not easy to put the fuel supply system products such as Fuel Pump Module (FPM) and Fuel Injector intended for four-wheel vehicles. Therefore, downsizing of these components are being required. In addition, weight reduction is also an important design factor in terms of improvement in fuel efficiency and driving performance. To meet these needs, we focused on motorcycles to optimize the design. We have been standardizing these components and starting mass-production in order since 2002. This paper introduces FPM and Fuel Injector that were newly developed for motorcycles.
