Engine Bench Testing
Engine bench testing is an essential step in engine development, maintenance, and repair. This type of testing provides valuable insight into the performance, efficiency, and reliability of engines being developed or diagnosed since these operations are performed in simulated real-world operating conditions.
In short, a bench test helps engineers identify potential issues and optimize engine performance before deployment. However, these tests are only as good as the equipment used to perform them, which is why we’re discussing bench testing engines.
Types of Engine Test Benches
Not all test benches for engines are the same. Test benches often come in various configurations, each designed to evaluate the specific aspect of engine performance. Almost universally, these include dynamometer testing, emissions testing, and durability testing. Here’s what you need to know about them:
Dynamometer Testing
Dyno testing is one of the most common testing methods, as it measures an engine's power output, torque, and rotational speed by applying a controlled load. This type of testing provides important data on engine efficiency, power curves, and fuel consumption under various conditions.
Furthermore, dyno testing and data loggers allow engineers to fine-tune engine parameters for optimal performance and efficiency, especially when developing high-performance engines and ensuring they meet performance specifications.
Emissions Testing
Emission testing is important for testing the environmental impact of a particular engine model. It measures the levels of pollutants emitted by the engine, including carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter.
Emission test benches often come equipped with advanced sensors to accurately capture and quantify these emissions. They’re also used to identify and mitigate the sources of excessive emissions, allowing engineers to ensure that the product complies with environmental regulations and standards. This helps manufacturers avoid fines and penalties and contributes to a cleaner and more sustainable environment.
Durability Testing
Durability testing assesses the long-term reliability and robustness of an engine, and this particular type of testing involves running the engine continuously for extended periods of time, exposed to different loads. This approach simulates real-world use, and it’s often employed to identify potential wear and tear issues associated with the current prototype iteration.
Durability engine bench testing is designed to monitor various parameters, including temperature, pressure, and vibration, to detect early signs of component degradation or failure. Conducting these tests allows manufacturers to ensure that their engine maintains performance and reliability over its expected service life, thus reducing the risk of unexpected failures and costly repairs.
Elevating Engine Reliability Through Bench Testing
As previously stated, engine bench testing plays a crucial role in enhancing engine reliability and performance, mostly by providing engineers with detailed and accurate data on engine behavior. This allows engineers to identify and address any potential issues before the engines are even deployed.
A proactive approach helps prevent costly failures and recalls, improves fuel efficiency, and reduces environmental impact. Additionally, engine bench testing also dives into continuous improvements in engine design and automotive manufacturing processes, leading to the development of better and more efficient engines.
Best Equipment for Bench Testing
While there is no universal testing bench for engine bench testing, KEYENCE’s NR-X Series multi-point data loggers provide an easy and reliable way for engineers to read and record several parameters from various critical points within the engine or the vehicle. Furthermore, the system can be wired to multiple remote units, significantly reducing the need for complex wiring of the test points often associated with different measurements.
