The paper considers the elements of the control system of fuel injection, allowing to adjust the response time of high speed electromagnets, depending on the operating mode of internal combustion engine. The aim of the study is to improve operational characteristics of the control system, allowing to reduce response time of solenoid injectors. The response time, especially at high engine speeds, affects the completeness of combustion and environment ecology. Dosing the amount of fuel depends on the duration of electric pulse supplied to the winding of solenoid injectors electronic control system. The duration of an electrical pulse injector control is calculated by the microcontroller of the electronic system of engine control module (ECM) based on signals of sensor values of throttle opening, air temperature, engine temperature, engine speed,
load, and other sensors. Stability of indicators of the injector is largely determined by the performance of its valve. For this reason, when designing high-speed electromagnets reducing response time and time of the release is said to be a high priority. 

Key words: the control system, the internal combustion engine, the fuel injection system, performance, spray nozzle, converter parameters of electric energy, the response time of the injector rise time current travel time of the armature of the injector, exhaust gas toxicity.
