Air Fuel Ratio of Petrol Engine
An experimental investigation was undertaken to examine air-to-fuel AF ratio effects on performance and emission of a fuel injected lean-burn natural gas engine. For a gasoline petrol engine the stoichiometric air fuel ratio is around 1471. Air Fuel Requirement In Si Engines Automobile The combustion is possible even is the AFR is different than stoichiometric. . 1 to 17. The scientifically perfect mixture for normal petrol is 1471 that is 147 times the mass of air to fuel but that doesnt mean a car should run at that far from it. The following figure shows the. The limit is around lambda 125 rich and there is no limit for lean as little needed to run the engine. 1 is the correct mixture of air and petrol which would result in burning without leaving an excess of air and fuel. This means that in order to burn completely 1 kg of fuel we need 147 kg of air. Step 1 Find the chemical equation of the oxidation
