Witryna8 kwi 2013 · second-stage ignition and reducing unburned hydrocarbons from the injector region. Because of limitations in the fuel injection system, only two-injection schedules were tested, one with a short, close-coupled post injection (injection dwell ≈ 1 °CA) and one with a longer post-injection duration and dwell (injection dwell ≈ 3 °CA). WitrynaAlkynes: Alkynes are unsaturated hydrocarbons containing C≡C triple covalent bonds in their molecules.They are represented by a general formula C n H 2n-2. Acetylene (C 2 H 2) (IUPAC name: ethyne) is the simplest alkyne molecule.. A C≡C triple covalent bond consists of 1 sigma and 2 pi bonds, respectively.It is stronger and thus shorter than a …
