(autoinsidernews) вЂ" Mitsubishi will begin selling a flex-fuel vehicle in Brazil sometime later this year, and is developing a flex-fuel vehicle for launch in the States sometime in 2009, the company said today. Flex-fuel vehicles account for more than four-fifths of the Brazilian auto market, and are gaining popularity with automakers in the United States.
Mitsubishi states that its FFV system will use sensors to measure oxygen in the exhaust gases, which allows the system to infer the concentration of ethanol in the fuel. The system will modify both the amount of fuel injected and spark timing вЂ" allow for any blend of ethanol between zero and 100 percent. The system will deliver similar engine performance, as well as fuel consumption and emissions on a par with gas-only vehicles. This allows users to get the same performance expected from a traditional gasoline engine, along with similar emissions and fuel consumption, reports Trend.
Concentration of ethanol in the fuel to be inferred, so that the amounts of fuel injected and the ignition spark timing can be optimized. As a result, the engine can handle gasoline-ethanol fuel mixtures with proportions of ethanol between 0% and 100%. The overall design achieves dynamic (engine) performance and environmental performance (fuel consumption and exhaust emissions) on a par with gasoline vehicles.
