The control system incorporates a feedback loop with strategically placed temperature sensors, ensuring uniform temperature distribution throughout the chamber. The user-friendly control panel allows for precise programming of temperature profiles, including rapid temperature changes and extended soak times, mimicking real-world driving conditions like cold starts in winter or heat soak in traffic.
  • Humidity Control: The humidity control system can achieve humidity levels from 10% to 95% RH, with an accuracy of ±3% RH. It employs a combination of steam injection and dehumidification techniques, along with a carefully designed air circulation pattern. Humidity sensors continuously monitor the internal environment, and the control system adjusts accordingly to create the desired humidity levels. This is crucial for testing the effects of moisture on engine components, such as corrosion of metal parts or the performance of intake systems in humid conditions.
  • Altitude Simulation: The chamber can simulate altitudes up to 5000 meters. By adjusting the air pressure and density, it replicates the reduced oxygen levels and lower atmospheric pressure at high altitudes. This enables the evaluation of how engines and powertrains perform in mountainous regions or during high-altitude driving, including changes in combustion efficiency, power output, and turbocharger performance.
  • Dust and Particulate Injection: To assess the impact of dirty and dusty environments, the chamber is equipped with a dust and particulate injection system. It can introduce controlled amounts of various types of dust, sand, and other particulates into the testing environment, allowing for the study of how engines and powertrains handle the ingress of such contaminants. This is especially important for off-road and commercial vehicle applications.
• Advanced Instrumentation and Data Acquisition
  • The chamber is outfitted with a comprehensive suite of sensors and instrumentation. In addition to temperature, humidity, and pressure sensors, it includes sensors for measuring engine performance parameters such as torque, horsepower, fuel consumption, and exhaust emissions. These sensors are connected to a high-speed data acquisition system that records and stores all the relevant data. The data acquisition system offers a sampling rate of up to 1000 samples per second, ensuring that even the most rapid changes in engine performance or environmental conditions are accurately captured. The collected data can be accessed and analyzed in real-time or retrieved later for in-depth studies. The system is also compatible with automotive engineering software, enabling detailed reports and graphical representations of the test results.

This allows for the accommodation of different sizes and types of engines and powertrains, from small automotive engines to large commercial or industrial power units.
• Temperature Cycling Rate: Can perform temperature cycles at a rate of 2 to 5 cycles per hour, depending on the specific test requirements. For example, it can rapidly cool from +80°C to -20°C in a matter of minutes and then heat back up, subjecting the engine or powertrain to significant thermal stress, which is essential for evaluating thermal fatigue resistance.
• Humidity Cycling Rate: The humidity can be cycled within 15 to 30 minutes, allowing for the simulation of rapid changes in moisture conditions, such as transitioning from a dry desert environment to a humid rainforest-like atmosphere.
• Altitude Change Rate: The chamber can simulate changes in altitude at a rate of up to 1000 meters per minute, replicating the rapid ascents and descents that vehicles may experience in mountainous terrains.
• Dust and Particulate Concentration: The dust and particulate injection system can introduce concentrations ranging from 10 milligrams per cubic meter to 1000 milligrams per cubic meter, depending on the desired test severity.
• Data Acquisition Rate: The high-speed data acquisition system samples sensor data at a rate of 500 to 1000 samples per second, providing detailed and accurate information about the engine and powertrain performance during testing.

4. Product Functions

• Realistic Environmental Simulation for Engine and Powertrain Evaluation
  • The primary function of this chamber is to provide a highly accurate and realistic simulation of the environmental conditions that engines and powertrains face. By precisely controlling temperature, humidity, altitude, and particulate levels, it allows for the assessment of how these components perform in different scenarios. For example, it can determine if an engine's fuel injection system needs to be adjusted for optimal performance at high altitudes or if a powertrain's cooling system is sufficient to handle extreme heat. This information is invaluable for automotive engineers to optimize designs, improve efficiency, and enhance the overall reliability of engines and powertrains.
  • The ability to conduct repeatable tests with different environmental profiles is also a crucial function. This helps in comparing the performance of different engine models or powertrain configurations and identifying the most suitable design for specific applications. For instance, a manufacturer can test multiple prototypes of an engine under the same set of temperature and altitude cycling conditions and analyze the results to select the best-performing version.
• Enhanced Product Quality and Research Capabilities
  • Through comprehensive testing in the Customized Walk-In Environmental Chamber, automotive product developers can identify and address potential issues in their designs. If an engine shows signs of reduced power output or increased emissions during a particular environmental test, appropriate modifications can be made, such as adjusting the air-fuel mixture, improving the turbocharger design, or enhancing the filtration system. This leads to the development of higher-quality engines and powertrains, reducing the risk of failures in the field and improving customer satisfaction. In the research and development field, it allows for the exploration of new technologies and materials, providing valuable data on their performance under different environmental conditions. For example, researchers can study the effects of using new lightweight alloys in engine components or the impact of advanced lubricants on powertrain performance in extreme temperatures.
