Abstract: The article presents experimental and numerical analysis of the diesel and aviation fuel Jet A-1 injection characteristics. The injection experiments were conducted using a high pressure common rail injection system. The injection characteristics were analyzed using an injection rate measuring instrument according to the Bosch method. The injection rate, cycle injection quantity, injection delay and injection duration were analyzed at 85.0 MPa, 115.0 MPa and 140.0 MPa injection pressures and 1.3 ms injection energizing time. As the results show, the peak mass injection rate of jet fuel was at 85.0 MPa injection pressure lower by 2.3 % only compared to diesel fuel. By increasing the injection pressure this difference decreases. However, the volumetric injection rates were slightly lower for diesel fuel. The injection delay was 0.3 ms for diesel fuel and 0.27 ms for jet fuel at 85.0 MPa and 115.0 MPa injection pressure, and 0.3 ms for both fuels at 140.0 MPa injection pressure. The injection duration in all cases was longer than the energizing duration of the injector. The discharge coefficient of jet fuel was by 6.5 % higher than that of diesel fuel. The experimental results were compared with the numerical simulation results. The common rail injector model was created with AVL BOOST Hydsim software. The measured pressure in the injection duct was used to validate the model in addition to the discharge coefficient and injection rate. The comparison of the simulated injection rate with the experimental data shows that the Boost-Hydsim common rail injector model gives good results for both standard diesel fuel and jet fuel
