To ensure the proper functioning of the diesel engine after a repair, it is necessary and essential to subject it to a dynamometric test on a test bench, in order to verify that the power and parameters recommended by the manufacturer are met. This article aims to demonstrate the importance of using a test dynamometer as a quality tool to study fuel consumption in a CATERPILLAR C9 diesel engine when subjected to different angular speed regimes. The research type is applied, with a quantitative approach, and the research design is experimental. The goal is to determine the actual fuel consumption and the variation in engine efficiency during a dynamometer test. These tests will provide data to manage, monitor, and control the resources to be used during the dynamometer testing processes. To achieve this, information has been collected such as fuel consumption, injection frequencies, injection duration, and the average current of the IAP control valve solenoid. All these parameters will be measured and interpreted through spectra of the actuator signals of the injectors and solenoid valve when the CATERPILLAR C9 diesel engine is subjected to different speed regimes. The results of fuel consumption at low idle speeds of 800 RPM to a maximum speed of 2000 RPM were analyzed and verified, finding a directly proportional relationship with fuel consumption. Additionally, the relationship between fuel consumption and the actuator signals of the IAP valve solenoids and injectors was determined. This article confirms the importance of studying and analyzing fuel consumption in relation to the mechanical and electronic actuation of the C9 diesel engine, using a test dynamometer. In conclusion, this tool allows verification of how fuel consumption is directly related to different speed regimes, as well as other parameters such as engine temperatures and pressures.
