WebJun 18, 2024 · An engine running either lean or rich can lead to reduced fuel economy, increased tailpipe emissions, and engine performance problems (e.g., misfiring). … 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.

WebStoichiometric or Theoretical Combustion is the ideal combustion process where fuel is burned completely. A complete combustion is a process burning all the carbon (C) to (CO 2), all the hydrogen (H) to (H 2 O) and all the sulphur (S) to (SO 2).. With unburned components in the exhaust gas such as C, H 2, CO, the combustion process is uncompleted and not … WebDon't know if this is why they made the choice, but O-rich let's you have a gas-gas combustion rather than a gas-liquid combustion. Gas-gas has significantly better mixing, which can result in dramatically simpler injectors. Gas-gas occurs because the oxygen is gas from the preburner. The fuel is gas from being used to regeneratively cool the ...
