WebDec 2, 2024 · Sometimes, an (O2) sensor gets “lazy” because of old age or contamination. Then, the computer may not be able to adjust the fuel mixture quickly enough, as the engine’s operating conditions change. (O2) sensors that are failing tend to read lean, which causes the fuel system to run overly rich to compensate. Signs Of A Bad Oxygen Sensor WebOct 9, 2024 · When measuring air/fuel mixture using lambda, stoich will always equal one (1) for any fuel. Lean or Rich Mixtures. When an air/fuel mixture has too much fuel, it is rich. When there is not enough fuel, it is lean. An AFR higher than stoich = lean. An AFR lower than stoich = rich. A lambda value higher than 1 = lean. A Lambda value lower …

WebStoichiometric ratios are also denser - H2, methane, and RP-1 are all significantly less dense than LOX, and so running fuel rich decreases density and increases tank mass, and this especially shows with hydrogen, where a stoichio ratio is over 14% denser (a lot, when you consider the rocket equation's exponential nature). WebA mixture less than normal full rich for takeoff and climb below 5,000 feet DA would be too lean. In these operating modes insufficient fuel flow could invite detonation and internal heating. The climb above 5,000 feet DA to cruising level should be as rich as possible and still provide smooth engine operation.

• S1.5400—First staged combustion rocket engine used on the Blok L upper stage. • NK-33—Soviet engine developed for the never-flown upgraded version of the N-1 launch vehicle. Later sold to Aerojet Rocketdyne and refurbished/remarketed as the AJ-26 (used on Antares block 1 launch vehicles in 2013–2014). In use on the Soyuz-2-1v. If the flame has too much oxygen, an oxidizing flame is produced. When the amount of oxygen increases, the flame shortens due to quicker combustion, its color becomes a more transparent blue, and it hisses/roars. With some exceptions (e.g., platinum soldering in jewelry), the oxidizing flame is usually undesirable for welding and soldering, since, as its name suggests, it oxidizes the metal's surface. The same principle is important in firing pottery.
