No, it is not. Carbon monoxide is produced by the incomplete combustion of petrol in air. Petrol is octane (C8H18), containing no oxygen atoms, whereas carbon monoxide, CO, has an oxygen atom. Complete combustion of octane goes: C8H18 + 12.5(O2 +3.76N2) --> 8CO2 + 9H2O + 47N2 Petrol Air Carbon dioxide Nitrogen Water Thus in a petrol fire with plenty of oxygen, no carbon monoxide is produced. However in a car's cylinder, there is likely to be more fuel and less oxygen than in this idealised combustion situation. There will still be mostly carbon dioxide and water as combustion products, but some of the carbon will partially oxidise carbon to carbon monoxide rather than dioxide. Although CO2 is a greenhouse gas, it is a less immediately dangerous substance than CO, which sticks to your red blood cells tighter than oxygen does - so tightly, in fact, that it won't let go, and the capacity of your blood to carry much-needed oxygen to your cells. Instead of bright red oxyhaemoglobin, CO combines with blood to produce cherry-pink carboxyhaemoglobin. A sign of CO poisoning is a cherry-pink complexion.

Carbon dioxide is not in fossil fuel. Burning fossil fuels releases carbon monoxide as the result of a chemical reaction.
