The FFVs under study operates on either M85 or M0 or any mixture of the two. Nissan has been actively conducting reseach and development on flexible fuel vehicles (FFVs) to explore the possibilities for long-range energy conservation and air quality improvement. The engine converted for use in these FFVs is a 1.6 liter, four-cylinder in-line powerplant, with dual overhead camshafts and four valves per cylinder. It employs the Nissan Variable valve timing Control System (NVCS). The fuel sensor for measuring the methanol concentration in the fuel has been improved both in terms of accuracy and durability. This paper describes the engine performance and exhaust emission levels (formaldehydes unburned methanol and HC emissions) obtained with both M85 and M0.

Nissan has recently developed and begun driving tests of a fuel cell vehicle equipped with a methanol reformer that produces hydrogen through the use of a catalyst to induce chemical reactions between methanol and water. With this onboard fuel cell system, only methanol in the form of a liquid fuel needs to be supplied, making the system highly practical as an automotive powertrain for near-future application. The Nissan Fuel Cell Vehicle (FCV) adopts a high-efficiency neodymium magnet synchronous traction motor combined with lithium-ion batteries that enable the vehicle to achieve optimum electric power by switching between a fuel cell-powered driving mode and a battery-powered driving mode. This presentation will cover the current status of the FCV development program and driving test results.
