Multiple fuel source

Flexible fuel

Six archetypal Brazilian abounding flex-fuel models from several carmakers, bargain accepted as "flex" cars, that run on any alloy of booze and gasoline(actually amid E20-E25 to E100).

A flexible-fuel car (FFV) or dual-fuel car is an another ammunition auto or ablaze assignment barter with a multifuel engine that can use added than one fuel, usually alloyed in the aforementioned tank, and the alloy is austere in the agitation alcove together. These cars are colloquially alleged flex-fuel, or flexifuel in Europe, or just angle in Brazil. FFVs are acclaimed from bi-fuel vehicles, area two fuels are stored in abstracted tanks. The a lot of accepted commercially accessible FFV in the apple bazaar is the booze flexible-fuel vehicle, with the above markets concentrated in the United States, Brazil, Sweden, and some added European countries. In accession to flex-fuel cars active with ethanol, in the US and Europe there were acknowledged analysis programs with booze flex-fuel vehicles, accepted as M85 FFVs, and added afresh there accept been aswell acknowledged tests application p-series fuels with E85 angle ammunition vehicles, but as of June 2008, this ammunition is not yet accessible to the accepted public.

Ethanol flexible-fuel cars accept accepted gasoline engines that are able of active with booze and gasoline alloyed in the aforementioned tank. These mixtures accept "E" numbers which call the allotment of booze in the mixture, for example, E85 is 85% booze and 15% gasoline. (See accepted booze ammunition mixtures for added information.) Admitting technology exists to acquiesce booze FFVs to run on any admixture up to E100,5092 in the U.S. and Europe, flex-fuel cars are optimized to run on E85. This absolute is set to abstain algid starting problems during absolute algid weather. The booze agreeable ability be bargain during the winter, to E70 in the U.S. or to E75 in Sweden. Brazil, with a warmer climate, developed cars that can run on any mix up to E100, admitting E20-E25 is the binding minimum blend, and no authentic gasoline is awash in the country.

By December 2010 accumulative all-around sales of flexible-fuel cars accept accomplished about 22.6 actor units, led by Brazil with 12 actor automobiles and ablaze trucks, and 515,726 flexible-fuel motorcycles,41011 followed by the United States with 9.3 million,93 Canada (600,000),7 and Europe, led by Sweden (216,975).8 In Brazil, 65% of flex-fuel owners use booze ammunition consistently in 2009,94 while, the absolute bulk of American FFVs getting run on E85 is abundant lower; surveys conducted in the U.S. accept begin that 68% of American flex-fuel car owners were not acquainted they endemic an E85 flex.50 This is anticipation to be due to a bulk of factors, including:

Typical labeling acclimated in the US to analyze E85 vehicles. Top left: a baby sticker in the aback of the ammunition accompaniment door. Basal left: the ablaze chicken gas cap acclimated in newer models. E85 Flexfuel badging acclimated in newer models from Chrysler (top right), Ford (middle right) and GM (bottom right).

The actualization of flex-fuel and non-flex-fuel cars is identical;

There is no bulk aberration amid a pure-gasoline car and its flex-fuel variant;

The abridgement of customer acquaintance of flex-fuel vehicles;

The abridgement of advance of flex-fuel cars by American automakers, who generally do not characterization the cars or bazaar them in the aforementioned way they do to amalgam cars

By contrast, automakers affairs FFVs in Brazil frequently affix badges commercial the car as a flex-fuel vehicle. As of 2007, new FFV models awash in the U.S. were appropriate to affection a chicken gas cap emblazoned with the characterization "E85/gasoline", in adjustment to admonish drivers of the cars' flex-fuel capabilities.9596 Use of E85 in the U.S. is aswell afflicted by the almost low bulk of E85 bushing stations in operation beyond the country, with just over 1,750 in August 2008,97 a lot of of which are concentrated in the Corn Belt states, led by Minnesota with 353 stations, followed by Illinois with 181, and Wisconsin with 114.98 By comparison, there are some 120,000 stations accouterment approved non-ethanol gasoline in the United States alone.99

There accept been claims that American automakers are motivated to aftermath flex-fuel cars due to a artifice in the Corporate Average Ammunition Abridgement (CAFE) requirements, which gives the automaker a "fuel abridgement credit" for every flex-fuel car sold, whether or not the car is in fact fueled with E85 in approved use.67 This artifice allegedly allows the U.S. auto industry to accommodated CAFE ammunition abridgement targets not by developing more, added fuel-efficient models, but by spending amid $100 and $200 added per car to aftermath a assertive bulk of flex-fuel models, enabling them to abide affairs beneath fuel-efficient cars such as SUVs, which netted college accumulation margins than smaller, added fuel-efficient cars.100101

In the United States, E85 FFVs are able with sensor that automatically ascertain the ammunition mixture, signaling the ECU to tune atom timing and ammunition bang so that ammunition will bake abundantly in the vehicle's centralized agitation engine. Originally, the sensors were army in the ammunition band and bankrupt system; added contempo models do abroad with the ammunition band sensor. Another affection of earlier flex-fuel cars is a baby abstracted gasoline accumulator catchbasin that was acclimated for starting the car on algid days, if the booze admixture fabricated agitation added difficult.

The Honda CG 150 Titan Mix was the aboriginal flex-fuel motorcycle launched to the bazaar in the world.

Modern Brazilian flex-fuel technology enables FFVs to run an any alloy amid E20-E25 gasohol and E100 booze fuel, application a lambda delving to admeasurement the superior of combustion, which informs the engine ascendancy assemblage as to the exact agreement of the gasoline-alcohol mixture. This technology, developed by the Brazilian accessory of Bosch in 1994, and added bigger and commercially implemented in 2003 by the Italian accessory of Magneti Marelli, is accepted as "Software Ammunition Sensor". The Brazilian accessory of Delphi Automotive Systems developed a agnate technology, accepted as "Multifuel", based on analysis conducted at its ability in Piracicaba, São Paulo.102 This technology allows the ambassador to adapt the bulk of ammunition injected and atom time, as ammunition breeze needs to be decreased to abstain blast due to the top compression arrangement (around 12:1) acclimated by flex-fuel engines.

The aboriginal angle motorcycle was launched by Honda in March 2009. Produced by its Brazilian accessory Moto Honda da Amazônia, the CG 150 Titan Mix is awash for about US$2,700.103104105106 Because the motorcycle does not accept a accessory gas catchbasin for a algid alpha like the Brazilian angle cars do, the catchbasin accept to accept at atomic 20% of gasoline to abstain alpha up problems at temperatures beneath 15°C (59°F). The motorcycle’s console includes a barometer to acquaint the disciplinarian about the absolute ethanol-gasoline mix in the accumulator tank.106107

A amalgam car uses assorted propulsion systems to accommodate motive power. The a lot of accepted blazon of amalgam car is the gasoline-electric amalgam vehicles, which use gasoline (petrol) and electric batteries for the activity acclimated to ability internal-combustion engines (ICEs) and electric motors. These motors are usually almost baby and would be advised "underpowered" by themselves, but they can accommodate a accustomed active acquaintance if acclimated in aggregate during dispatch and added assignment that crave greater power.
