In Brazil, 65% of flex-fuel car owners were using ethanol fuel regularly in 2009, [25] while, the actual number of American FFVs being run on E85 is much lower; surveys conducted in the U.S. have found that 68% of American flex-fuel car owners were not aware they owned an E85 flex.

[B]y 2025 the last hold outs should likely be retiring their fuel cell dreams.” [151] A 2019 video by Real Engineering noted that using hydrogen as a fuel for cars does not help to reduce carbon emissions from transportation. The 95% of hydrogen still produced from fossil fuels releases carbon dioxide, and producing hydrogen from water is an ...
This type is actually electric vehicle that is powered by electric energy generated using onboard fuel cell. Fuel cell uses hydrogen stored in hydrogen tanks and oxygen from the air to create water and electricity. Water is discarded but electricity is used for propulsion. Similarly to Hybrid Electric Vehicle, there is a small traction battery.
When gas prices soar, the Sentra's small fuel tank can make filling up less heartbreaking than larger cars with even bigger ones. Base price: $21,745 EPA combined/city/highway: 34/30/40 mpg
This means that a bicycle will use between 10 and 25 times less energy per distance travelled than a personal car, depending on fuel source and size of the car. This figure does depend on the speed and mass of the rider: greater speeds give higher air drag and heavier riders consume more energy per unit distance. In addition, because bicycles ...
Therefore, depending on how the fuel is metered, the maximum output for a hydrogen engine can be either 15% higher or 15% less than that of gasoline if a stoichiometric air/fuel ratio is used. However, at a stoichiometric air/fuel ratio, the combustion temperature is very high and as a result it will form a large amount of nitrogen oxides ( NO ...
There are other methods to increase the amount of oxygen available inside the engine; one of them, is to inject nitrous oxide, (N 2 O) to the mixture, and some engines use nitromethane, a fuel that provides the oxygen itself it needs to burn. Because of that, the mixture could be 1 part of fuel and 3 parts of air; thus, it is possible to burn ...
The heart of the Mitsubishi's MVV system is the linear air–fuel ratio exhaust gas oxygen sensor. Compared with standard oxygen sensors, which essentially are on-off switches set to a single air/fuel ratio, the lean oxygen sensor is more of a measurement device covering the air/fuel ratio range from about 15:1 to 26:1.
