What precaution should we take to prevent incomplete combustion of fuel
Answers
Proper air to fuel ratio: For complete combustion of the fuel each droplet should be surrounded by air which is equal or greater to the air-fuel ratio.
Proper atomisation of fuel: Fuel should be sprayed in the form of mist so that it can mix with air for proper combustion.
Heat: Heat required for combustion of different fuels are also different. Petrol or Gasoline need very less heat to ignite as it vaporises but not the diesel fuel. It needs much higher heat than the gasoline counterparts. Proper heat should be provided for complete combustion.
Engine timing: Engine timing is very crucial for complete combustion as early spark can lead to a flame travelling into the intake valve and also it can lead to knocking.
After-burning: Prevent afterburning by introduction of multiple spark plugs so that the entire charge ignites simultaneously because there are chances that fuel exits the chamber unburnt. So make sure all the parts in the combustion chamber gets equal heat.
