| Video Discription | What Is Air Fuel Ratio? The explanation of this Air Fuel Ratio is Comparison between air and fuel As we know that, in the engine the power produced comes from a combustion Where the combustion process occurs due to the reaction of oxidizing agents Oxygen, fuel and activation energy This activation energy is generated by the release of heat in the form of fire We can see, so the fuel and air will mix Because the compression will cause heat The petrol fuel system is assisted with spark plugs This spark plug will give off a spark, thus triggering combustion in the engine The difference in composition greatly affects the results of combustion Next we short this term with AFR A burning is said to be stochiometric if Air and fuel are mixed at the right composition Example in the type of engine that runs on gasoline The ideal stochiometry is 14.7: 1 So simply put For 1 gram of fuel, it takes 14.7 grams of oxygen for combustion This ideal combustion will produce perfect combustion Even though in fact the combustion product is very difficult to achieve in perfect condition Incomplete combustion, will leave the remaining exhaust gas in the combustion chamber So that it will affect the performance of the engine Then, if the comparison is not reached, is it possible for combustion to occur? Actually the burning is still possible With a minimum of 12: 1 AFR, and a maximum of 20: 1 AFR There are coefficients that we can calculate, symbolized by Lambda Having a formula, the actual AFR is divided by the Ideal AFR When Lambda less than 1, it is called Rich or fat When Lambda = 1, we call it ideal Then when Lambda greater than 1, we call this Lean or skinny For Rich's condition, where there is not enough burned air So that there is residual fuel that does not burn and is wasted into the exhaust channel And for Lambda = 1, this means there is no remaining oxygen and fuel wasted For the Lean condition, Lambda greather 1, this means there is more oxygen than needed Then how does it affect engine performance? We can see this graph This is Rich's condition And this is the Lean condition The red line is power The black line is fuel consumption This line is an ideal condition where Lambda = 1, AFR 14,7: 1 Looking at this graph, we can conclude that AFR greatly affects power and fuel consumption For Lean conditions, we will get the most economical fuel consumption As for Rich's condition, we will get the maximum energy So indirectly, we cannot get maximum power With economical fuel consumption [XHF00kHwsyY] |
