What means tank to wheel?
The term Tank-to-Wheel (TTW) refers to a subrange in the energy chain of a vehicle that extends from the point at which energy is absorbed (charging point; fuel pump) to discharge (being on the move). The generic term that subsumes Tank-to-Wheel and Well-to-Tank is Well-to-Wheel (WTW).
How do you calculate co2 fuel consumption?
An average consumption of 5 liters/100 km then corresponds to 5 l x 2640 g/l / 100 (per km) = 132 g CO2/km. Petrol: 1 liter of petrol weighs 750 grammes. Petrol consists for 87% of carbon, or 652 grammes of carbon per liter of petrol.
How much CO2 does a car emit?
A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year. Every gallon of gasoline burned creates about 8,887 grams of CO2.
Are hybrids better for the environment?
They emit a lot of harmful pollutants as well as waste such as nitrogen gas, carbon dioxide, and carbon monoxide. Even these vehicles run on gas, which is an important, non-renewable, rare resource. Thus, hybrid cars are becoming more efficient in controlling against pollution.
What are the wheels on a tank called?
Tanks use high power engines to turn a toothed metal wheel called a sprocket. These sprocket teeth connect to corresponding grooves in the tanks’ linked metal tracks which the tanks road wheels run along.
How much gas does it take to make 1 megawatt?
Second: A high efficiency, natural gas-fired combined-cycle power plant might consume about 7000 Btus of gas to produce one kilowatt-hour of electricity. That would be about 7 cubic feet of natural gas. It would therefoe take about 7000 cubic feet of gas to produce one megawatt-hour.
How much CO2 do trees remove?
Pollution Reduction A mature tree absorbs carbon dioxide at a rate of 48 pounds per year. In one year, an acre of forest can absorb twice the CO2 produced by the average car’s annual mileage.
How much CO2 is produced by well to wheel?
In the following picture, we have considered BEV considering the current EU energy mix (106 g CO2/MJ) and what JEC (JRC, EUCAR, CONCAWE) are projecting in 2030, corresponding to 72g CO2/MJ. Well-To-Wheel emissions generated by the BEV in 2030 correspond to 37 g CO2/km.
What are the emissions of a well to wheel car?
Well-To-Wheel emissions generated by the BEV in 2030 correspond to 37 g CO2/km. A CNG car, with 94 g CO2/km tailpipe emissions, generates 114 gCO2/km at WtW level when fed with natural gas (fossil).
What are the objectives of the well to Wheels analysis?
The well-to-wheels analyses by JEC pursue the objectives of estimating: 1 greenhouse gas emissions, 2 energy efficiency and 3 industrial costs More
How does wheel to well analysis of EVs work?
These analyses are known as well to wheel studies. From these analyses, EVs have been shown to reduce energy consumption by up to 50% and GHG emissions by up to 60%.
