The function of the fuel system in an IC engine is to transfer the fuel from the storage tank to the engine cylinder in proper quantity to meet the load and speed requirement of the engine.
Since the SI engine and CI engine have different types of fuel requirements at the time of injection in the cylinder, there is a considerable difference in the fuel supply of these engines.
Generally, 9 to 10 m3 of air is required for consuming 1 liter of fuel by a four-stroke engine.
Air - Fuel ratio for petrol engine:
- Starting: 4 to 6
- Idling: 11 to 12
- Normal working: 14 to 18
- Acceleration: 9 to 11
