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.

How much co2 does a car emit per gallon?

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.

Does mpg improve over time?

A vehicle that is properly maintained will retain its efficiency for many years. The EPA tests vehicles with about 5,000 miles on the odometer to account for the break-in period since a vehicle’s fuel economy will typically continue to improve over the first several years of ownership.

Why is mpg so low?

A bad fuel injector or dirty/old fuel filter can drastically affect the flow of fuel into the engine. A fuel system problem is one of the most common causes of poor gas mileage. The more you run your A/C, the lower gas mileage you will get.

At what speed is mpg calculated?

Vehicles are tested at a top speed of 80 mph in order to calculate the highway mpg estimates. EPA utilizes five test cycles to represent real-world driving conditions.

How does 1 gallon of gas become 20 lb of CO2?

Each carbon atom in the gasoline combines with two oxygen atoms already in the air. So the carbon in a gallon of gasoline (weighing 6.3 pounds) weighs 5.5 pounds (. 87 x 6.3 pounds = 5.5 pounds). So, multiply the weight of the carbon times 3.7, which equals 20 pounds of carbon dioxide!

How much CO2 does a gallon of jet fuel produce?
