Explanation:
Petrol engines work by burning fuel to create energy which powers the vehicle. During this process, several gases are produced, which are then exhausted out of the engine through the exhaust system.
The exhaust gases from a petrol engine typically consist of:
- Carbon dioxide (CO2)
- Carbon monoxide (CO)
- Water vapour (H2O)
- Nitrogen (N2)
- Oxygen (O2)
- Unburnt hydrocarbons (HC)
Of these gases, only nitrogen is exhausted out without burning and without transformation. This is because nitrogen is an inert gas that does not participate in the combustion process.
During combustion, the fuel and air mixture is ignited by a spark, which causes the oxygen and hydrocarbons to react and produce energy in the form of heat. The nitrogen in the air, however, remains unchanged and simply passes through the engine and out of the exhaust system.
In summary, the exhaust gases from a petrol engine contain several gases, including nitrogen, which is exhausted out without burning or transformation because it is an inert gas that does not participate in the combustion process.
