Review article

The design of the nozzle on the gas injector for gas and gas-diesel engines with distributed and phased gas supply is proposed to increase the uniformity of the gas-air mixture entering the engine cylinders during the intake process. A method for calculating the flow capacity of the nozzle through the pressure drop is given, which adequately assesses the effect of the nozzle design on the gas supply conditions, which will allow adjusting the settings of the gas fuel supply system in a real engine.
