    Abstract
  • Focusing on the performance recovery and knock suppression of two-stroke gasoline engine after switching to aviation kerosene，a one-dimensional simulation model of kerosene engine was established by GT-power，and the knock of kerosene engine was predicted and optimized.The simulation results showed that delaying the ignition time，the mixture far below and far greater than the theoretical air-fuel ratio can yield a certain inhibitory effect on knock.The experimental results verified the correctness of the simulation results.The control strategy of collaborative delaying ignition and increasing fuel injection was proposed and used for experimental researches.The results showed that the knock can be effectively suppressed at low speed and heavy load，the power recovery was generally more than 90% when the throttle was fully open.When the engine speed was 5 500 r/min，the power recovery can even reach 95.7% of the original engine.
