The high population growth of the planet led to a need for technological development for food production. The increase in the use of agricultural machines with diesel cycle engines has become indispensable in this process, which contributes to the emission of gases that pollute our planet. Therefore, conducting tests fuels from non-fossil renewable energies is of paramount importance for analyzing the performance of diesel cycle engines. Thus, this work aimed to develop a system to perform tests with the use of diesel and biodiesel with controlled temperatures in diesel cycle engines. Highlighting issues related to the use of alternative fuels in engines, with their main design characteristics, which influence the performance, efficiency and damage generated to diesel cycle engines. The work consists of the dimensioning of the heating system and materials used in the construction of the workbench, according to the schematic drawing of the system's operation and practical project execution. Functional tests were performed to calibrate the temperatures recorded by the sensors used in the water reservoir and at the fuel outlet. Tests were also performed with diesel and biodiesel to verify the heating time and temperature control. In general, the system proved to be effective to perform tests on diesel cycle engines, which after calibrated showed no variations in the temperature recorded by the display with that shown by the thermometer. The 1700 Watt resistances achieved shorter heating times than the 1000 Watt resistances which resulted in greater practicality of the tests.
