This master's thesis describes the improvement and automation of a test bench for an internal combustion engine at the Universidad Politécnica de Madrid. Installed in the late 70s and initially used for engine testing, the test bench was recently adapted for educational purposes. However, outdated instrumentation presented issues regarding mostly the lack of automatization and poor data visualization that hindered the students' learning experience during laboratory experiments. The objective of the thesis was to modernize and automate the test bench while making it more suitable for teaching purposes. The improvements made to the test bench can be broken down into three categories, the first one being hardware improvements, which include the installation of a new atmospheric pressure sensor, reorganization of thermocouples’ wirings and recalibration of sensors.
