Petrol : 2 C8H18 + 25 O2 –> 16 CO2 + 18 H2O + energy
1 litre of Petrol produce 2.22 kg of CO2. (3087.72*0.7197=2224.64)
An average consumption of 5 liters/100 km then corresponds to 5 l x 2392 g/l / 100 (per km) = 120 g CO2/km.
Diesel C12H23: 4 C12H23 + 71 O2 –> 48 CO2 + 46 H2O + energy
1 litre of Diesel produce 2.63 kg of CO2. (3155.8*0.832=2625.6)
An average consumption of 5 liters/100 km then corresponds to 5 l x 2640 g/l / 100 (per km) = 132 g CO2/km.
LPG GPL: C3H8 + 5 O2 –> 3 CO2 + 4 H2O + energy
1 litre of LPG GPL produce 1.66 kg of CO2.
An average consumption of 5 liters / 100 km then corresponds to 5 l x 1665 g/l / 100 (per km) = 83 g of CO2/km
