Underhood Thermal Management & Engine Cooling Analysis - Application Note

Malaysian automobile manufacturer Proton needed to test the underhood thermal management and engine cooling performance in their new manual 5-speed Proton Persona 1.6 M/T Line. The thermal test program was designed to check underhood part performance in order to ensure that the parts were working within design requirements after being exposed to high temperatures during driving and climbing. Engine cooling analysis testing was performed to verify cooling performance under various types of driving patterns including high-speed runs, idling, and hot soak and dead soak. To collect enough temperature data to get a complete picture of the Persona’s thermal distribution and engine cooldown, Proton’s automotive engineers needed a high-performance, flexible data acquisition device for use in their test setups which supported large numbers of channels and was able to connect to the very broad range of thermocouple types the program would use.
