We support our customers right from the planning stage and are familiar with the legal requirements, practical necessities, and economic aspects of test chamber projects.
Test chamber for performance tests and emission tests on complete vehicles
Vehicles must reliably meet strict environmental and performance standards under all climatic conditions. To verify that vehicles can consistently meet these standards, manufacturers require precise and versatile test equipment that can simulate real driving situations under various environmental conditions, including extreme ones.
Weiss Technik develops customized dynamometer test chambers in which the efficiency of the drive train is tested under climatic stress during typical vehicle driving cycles. These dynamometer test benches are used to test the performance and emissions of complete vehicles, ensuring that they comply with national and international automotive industry standards.
Performing emission tests under extreme conditions
International guidelines stipulate rigorous vehicle emission testing under various climatic conditions. These range from Arctic cold, with temperatures well below freezing, to tropical heat, with high humidity. These tests must be carried out under precisely defined conditions, be reproducible, and comply with national and international automotive industry standards.
Ensuring temperature and humidity control
Temperature and humidity values are precisely defined for the prescribed emission and performance tests. These values must be maintained throughout the entire test period, and depending on the respective test standard, only minor deviations are permitted.
Capturing measurement data comprehensively
To make the best possible use of the data and measurements recorded during a test cycle, the dyno chambers operate with integrated measurement systems. These systems capture the required data and transmit it to connected analysis software.
Using sustainable and efficient refrigerants
The European F-Gas Regulation regulates the use of refrigerants that have a significant impact on the cooling capacity of air conditioning systems. It is therefore important to use innovative refrigeration systems with sustainable refrigerants in order to ensure that the required cooling capacity is available at all times.
Dyno chambers for measuring performance, exhaust gas and fuel consumption on the dynamometer
In dynamometer test rigs, the drive and braking torque of the wheels is transferred to a dynamometer in order to simulate driving cycles and measure performance values. The test rigs are equipped with high-precision measuring devices to record the required performance values. For special emission tests, the chambers are also equipped with an exhaust gas analysis system.
We plan, build, and implement chassis dyno chambers from a single source. The ventilation technology, dehumidification system, and refrigeration technology we implement comply with the latest standards. This also includes the use of the environmentally friendly refrigerant CO2 with a GWP of 1.
