The Role of Low Temperature Chemistry in the Autoignition of N-Butane

摘要: The authors studied the chemical aspects of compression ignition n-butane experimentally in a spark engine and theoretically using computer simulations with detailed kinetic mechanism. results these studies demonstrate effect initial charge composition on autoignition. Experimentally, when consisted 80% fresh 20% recycled products combustion, observed that autoignition was inhibited. On other hand, charging partial oxidation from previous motored cycle resulted enhanced low-temperature chemistry (with associated heat release temperature increase) They assessed how well model could predict modified to better simulate experimental observations. also preconditioning fuel-air affected process.
