“…In the ECU's hard drive, values are set based on the degree of motor warming, the time it takes to open, the time the injector remains open, and the amount of fuel injected. [1] Depending on the type of fuel system, the injector can be installed in a variety of locations, including: [2] • The central injector is a mono injector, which means that the fuel-injection system uses a single injector, which is mounted on the admissions galleria before the inlet valve of acceleration. It serves as a bridge between a carburetor and a full-fledged injector.…”

The paper presents a control circuit made in Xilinx and which allows the adjustment of the frequency and the duty cycle of the control signal of an injector. The control circuit contains an oscillator and a selection circuit that provide specific commands to a counter. The oscillator that provides the clock frequency of a counting circuit uses the Nexis 4 DDR module’s own frequency. This is to be divided to the desired value by means of a divider implemented soft which makes changing the frequency easy. The signal obtained at its output commands a counter at which the maximum value of numbers is changed by a circuit selection. Thus, the variable duty cycle of the output signal of the development board is obtained, which is amplified both in voltage and in current, for compatibility with the injector parameters. The paper presents waveform obtained when resistive load operation as well as quantities of fuel injected in a given time interval.
