  • In considering the deficiency of adjusting fuel injection amount or ignition advance angle to suppress knock on two-stroke kerosene engine, the coordinated injection-ignition control strategy for suppressing engine knock was proposed. A two-stroke spark ignition engine was taken as the test engine for comparative study, and its modeling and simulation analysis were carried out by using one-dimensional simulation platform. The MAPs of fuel injection amount and ignition advance angle were obtained by the method of design of experiment (DoE) after adopting the coordinated control strategy. The corresponding experimental investigations were conducted. The results showed that, at engine speed of 4800 r/min, compared with the single parameter of adjusting ignition advance angle to suppress knock intensity of kerosene engine, the optimized strategy was more effective. The specific fuel consumption showed a modest increase with reduced power loss and decreased exhaust temperature. The power recovery of kerosene engine can reach at least 88.3% of the burning gasoline at different loads; meanwhile, the power recovery can reach 96.2% under the condition of full load at engine speeds of 5000—6500 r/min, and the exhaust temperature can be controlled within 475 ℃, effectively promoting the performance of kerosene engine.
