How do you calculate CO2 emissions from fuel consumption?
How do you calculate CO2 emissions from fuel consumption?
1 liter of petrol weighs 750 grammes. Petrol consists for 87% of carbon, or 652 grammes of carbon per liter of petrol. In order to combust this carbon to CO2, 1740 grammes of oxygen is needed. The sum is then 652 + 1740 = 2392 grammes of CO2/liter of petrol.
What means fuel consumption?
Fuel consumption is the rate at which an engine uses fuel, expressed in units such as miles per gallon or liters per kilometer. Engine designers strive for more power, lower fuel consumption, lighter weight, and better reliability.
What is a good CO2 g km?
What is considered a ‘good’ CO2 emission level for a car? Anything less than 100g/km can be considered low – or good – CO2 emissions. Cars that produce 99g/km or less, and that were registered before 1 April 2017, owe no road tax.
How do I calculate CO2 emissions for my car?
The simplest way to calculate tailpipe emissions of CO2 is to measure fuel consumption. Just add your fuel bills each period to see how much CO2 you have produced. Burning a litre of diesel produces around 2.62 kgs of carbon dioxide, whereas petrol has a lower carbon content and produces about 2.39 kgs.
How do I find out my CO2 emissions?
Where do I find the CO2 emissions rating for my car? If you look in your V5C registration certificate for your car, the emissions rating is listed there. Or, you can find the fuel consumption and emissions information for a new or used car on the government certificate agency website.
How do you calculate CO2?
Carbon dioxide emissions per barrel of crude oil are determined by multiplying heat content times the carbon coefficient times the fraction oxidized times the ratio of the molecular weight of carbon dioxide to that of carbon (44/12).
How much petrol does a car use per km?
The actual formula to get km per litre is 100 divided by 8 = 12.5, meaning that your car will give you 12.5 km on one litre.
