In order to combust this carbon to CO 2 1920 grammes of oxygen is needed. The sum is then 720 + 1920 = 2640 grammes of CO 2 /liter diesel. An average consumption of 5 liters/100 km then corresponds to 5 l x 2640 g/l / 100 (per km) = 132 g CO 2 /km. Petrol: 1 liter of petrol weighs 750 grammes. Petrol consists for 87% of carbon or 652 grammes ...

How to Calculate the Stoichiometric Air-fuel Ratio ...

One oxygen molecule weighs: 2 * 16 = 32. The oxygen-fuel mass ratio is then: 2 * 32 / 1 * 16.042 = 64 / 16.042. So we need 3.99 kg of oxygen for every 1 kg of fuel. Since 23.2 mass-percent of air is actually oxygen we need : 3.99 * 100/23.2 = 17.2 kg air for every 1 kg of methane. So the stoichiometric air-fuel ratio of methane is 17.2.

Chapter 11: Combustion (Updated 5/31/10) - Ohio University

Atmospheric Air contains approximately 21% oxygen (O 2) by volume. The other 79% of "other gases" is mostly nitrogen (N 2) so we will assume air to be composed of 21% oxygen and 79% nitrogen by volume. Thus each mole of oxygen needed to oxidize the hydrocarbon is
