The industry is moving towards using alternative fuel sources such as electricity, hydrogen and solar power. Flex-fuel cars are the intermediate category between conventional and alternate-fuel cars. They can operate on a mixture of ethanol and petrol which can have a ratio percentage of up to 83% to 85%. This results in a significant reduction of carbon emissions because of the addition of ethanol to petrol.&nbsp;<\/p>\n\n\n\n<p>Let\u2019s go further into the details of flex-fuel cars, their function, advantages and drawbacks.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-function-of-a-flex-fuel-car\">The Function of a Flex-Fuel Car<\/h2>\n\n\n\n<p>A flex-fuel car is equipped with a flex-fuel engine which is a counterpart of a conventional <a href=\"https:\/\/www.dubizzle.com\/blog\/cars\/combustion-chamber-parts\/\" target=\"_blank\" rel=\"noreferrer noopener\">combustion engine<\/a>. These fuel tanks can store a mixture of ethanol and petrol and also enable the vehicles to run 100% on either of them. The blend of the fuel system is made resistive to ethanol since its effect can be corrosive and has higher octane. The most used type of ethanol oxygenate is E85. the working of a flex-fuel car is carried out by a <strong>flex-fuel composition sensor<\/strong> and<strong> electronic control module (ECM)<\/strong> which senses and adjusts the ratio of the fuels. The ECM is modified to withstand the higher content of oxygen in ethanol.<\/p>\n\n\n\n<p>Now that you are familiar with how flex-fuel car functions, let&#8217;s take a look at the components that are involved in the working.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-components-of-a-flex-fuel-car\">Components of a Flex-Fuel Car<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img
