Engine monitoring refers to the process of tracking and analyzing the performance and health of an engine, typically in vehicles or machinery. This involves using various sensors and diagnostic tools to collect data on parameters such as temperature, pressure, and fuel efficiency. By continuously monitoring these factors, potential issues can be identified early, helping to prevent costly repairs and ensuring optimal performance. Modern engine monitoring systems often include onboard computers that provide real-time feedback to the operator. These systems can alert users to abnormal conditions, such as overheating or low oil pressure, allowing for timely interventions. Technologies like OBD-II (On-Board Diagnostics) are commonly used in automobiles to facilitate this monitoring process.
