Roll-on test benches are an important tool for functional testing in the automotive industry. The software from rd electronic enables multiple tasks to be performed sequentially on a single test bench. This includes the unique integration of an engine hot test.
After assembly, 100% of internal combustion engines undergo a cold test. During the cold test, the engine is filled with oil but not with coolant and is driven by the test bench. Torque, leak tightness, and air mass are measured during this process. To validate the cold test, the first n engines of a new engine series undergo a hot test. This means the engine is fully supplied with operating fluids and fired up. During this process, the engine drives the hot test bench. The goal is to identify any gaps in the test coverage of the cold test in order to close them.
Like the cold test, the hot test is conducted at the engine plant.
In “Completely Knocked Down” engine production, hot test benches are not always available at the CKD engine plant. Shipping the engines by air freight for hot testing is expensive and time-consuming. To reduce costs and time, the engine hot test is performed at the CKD vehicle assembly plant. Here, the engine is tested on the roller test bench while installed in the vehicle. In addition to the aforementioned savings, this also eliminates the setup and teardown effort for the hot test engine test bench and the simulation of the vehicle electrical system.
Battery-powered electric mobility will largely replace internal combustion engine technology. However, the internal combustion engine is not expected to disappear entirely. For this future scenario, rd electronic offers a solution that allows new or older roller test benches to be upgraded to fully and comprehensively test the smaller volumes of internal combustion engine vehicles.
rd electronic is currently testing the hot-run software on roller test benches in collaboration with an innovative German OEM.
