Nikkei. Japan’s Denso is joining the ranks of parts suppliers such as Bosch and Delphi in developing auto fuel system components that are ethanol-compatible.
Toyota, Denso’s major customer, announced earlier this year that it will introduce E100-capable flex-fuel vehicles to the Brazilian market in the spring of 2007, and that it was “considering’ introducing flex-fuel vehicles to the US in consideration of policies to promote bioethanol fuels. (Earlier post.)
Furthermore, Japan is adopting a new national energy strategy designed to reduce the nation’s dependence on petroleum; one component of the new strategy is increasing the percentage of ethanol in gasoline from 3% (E3) to 10% (E10) by 2020. (Earlier post.)
Along with a fuel injection system designed for increased flow capacity to offset the lower energy generated by ethanol combustion, Denso is developing fuel system parts that can handle the corrosion and condensation that accompany ethanol usage, as well as sensors for measuring alcohol concentration.
The engine control software will need to be able to detect ethanol blends and adjust fuel and spark control to optimize efficiency.
