The paper presents the the new internal combustion engine working process and a new design of an electronically controlled engine injector in accordance with the requirements for environmental, technical and economical characteristics of automobile engines. One of the main requirements for the electronically-controlled injectors is a high operating speed. There has been considered a possibility to improve the operating speed of the injector. There has been studied the influence of pressure at the outlet of the high-pressure fuel pump on the operating speed of the developed electronically-controlled injector at different values of the electrical control impulse fed on the piezoelectric actuator. The investigation was carried out by the method of numerical experiment using a mathematical model. The results of numerical investigations are presented and analyzed; in the result, the optimal value of the pressure at the outlet of the high-pressure fuel pump is determined in terms of the operating speed of the developed injec
