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.

Hydraulic power steering is applied for petrol and diesel models of Infinity M series to provide supreme feeling of steering. Power assist of hydraulic power steering (here after called HPS), however, does not work when hybrid vehicle is in EV drive mode because the engine, which is the power source stops and the power is not supplied. Electric Power Steering (hereafter called EPS), therefore, “MUST” be installed to assist the power. Here comes the need that Nissan has developed our Hybrid EPS for Infinity M Hybrid model to keep providing supreme feeling of steering of hydraulic power steering without huge packaging change from the standard packaging of petrol & diesel models with hydraulic power steering. Our Hybrid EPS is the 1st hybrid EPS system in the world that is effectuated by oil pressure, and succesively realized by unique and excellent technology of Nissan.
