What is the stoichiometric air/fuel ratio?
about 14.7:1
How is stoichiometric air fuel ratio calculated?
Stoichiometric air means the minimum air in stoichiometric mixture. The stoichiometric air/fuel ratio (AFR) can be calculated from the reaction equation (g/g). For gas AFR is usually determined in m3/m3. The actual combustion air depends also on the assumed air excess (equivalence ratio or stoichiometric ratio).
What is meant by stoichiometric air fuel ratio in combustion?
The stoichiometric ratio is the exact ratio between air and flammable gas or vapor at which complete combustion takes place. The stoichiometric ratio of combustion varies for various fuels and oxidizers. If the engine has less air than the stoichiometric ratio, you have a rich mixture, because it is rich in gasoline.
What does the term stoichiometric mixture mean when used in relation to combustion of hydrocarbon fuels?
Stoichiometric combustion is a theoretical position in which the optimal amount of oxygen and fuel mix generates the most heat possible, and maximum combustion efficiency is achieved. There are no unburnt combustibles and no excess air.
What is the air fuel ratio at idle?
14.7:1
What happens if the fuel mixture is too rich?
When your engine is running rich, it will cause bad emissions. A rich air-fuel mixture will create black smoke, which will then come out from your exhaust pipe.
What is the difference between bank 1 and bank 2 on O2 sensor?
“Bank 1, Sensor 2” is the rear oxygen sensor. A V6 or V8 engine has two banks (or two parts of that “V”). Usually, the bank that contains the cylinder number 1 is called “Bank 1.”
Where is camshaft position sensor a bank 1 located?
The camshaft position sensor reacts to a toothed wheel on the camshaft, which gives the ECU constant information on its speed and position. Of course, the CMP is located on the engine, usually somewhere on the cylinder head, so it transmits CMP data to the ECU using wires.
Which side of engine is right bank?
If you were (theoretically) standing at the REAR of the engine, it would reveal: the opposite/opposing/far-side of the engine as being the FRONT, your right side Is The Right Side Of The Engine (also Bank 1), and your left side Is The Left Side Of The Engine (also Bank 2).
Which side is Bank 1 on GMC?
