Hyundai tests 42.5 lakh engines using cold bed tech. Here's what it means

Hyundai Motor India Limited (HMIL) has reached a milestone for its production operations with over 42.5 lakh engine tests through the Cold Bed Engine Testing method. The Cold Bed Engine Testing method uses electric power instead of fuel alternative verification, looking to reduce emissions and use of resources in engine quality checking. Cold Bed Engine Testing is a non-combustion engine testing technique that allows manufacturers to test engine performance without running the engine on fuel. The technology has been up and running since 2013, suggesting a larger trend within the industry to address greening of production related practices. Gopalakrishnan CS, Whole-time Director and Chief Manufacturing Officer, HMIL, stated that by testing over 42.5 lakh engines using zero-emission Cold Bed Engine Testing technology, the company has significantly advanced its commitment to eco-friendly manufacturing - curbing over 2 million kg of CO₂ emissions and optimizing efficiency with US $1 million in operational savings.

Cold Bed Engine Testing is a non-combustion engine testing technique that allows manufacturers to test engine performance without running the engine on fuel. Rather than using combustion, the crankshaft of the engine is turned with an electric motor. A sensor network captures high-level performance data—involving crankshaft angle, compression pressure, and cylinder performance. This enables precise engine integrity analysis without releasing pollution or needing coolant and water. How the system works Each engine is installed on a Cold Bed test stand, where a crankshaft is driven by an electric motor. High-accuracy sensors track numerous internal parameters when the engine is cold—that is, not started or cycled through heat—while the engine is being tested. Also watch: Hyundai Creta EV unveiled. What does it offer? Launch timeline, range, battery, charging explained All information collected is digitally documented, making it potentially retrievable and usable at some point in the future. This approach realizes Industry 4.0 technologies and removes some of the need for manual monitoring to reduce the time required for testing. Operational and environmental impact The Cold Bed process has allowed HMIL to eliminate the consumption of fuel, coolant, and water resorted to in the validation process by completely avoiding combustion in engine testing. The company says this has avoided a total of 2 million kilograms of CO₂ emissions and resulted in saving about $1 million in operational costs. Apart from emissions and cost, the process is also safer, as it eliminates the risk of handling fuel and running the engine live during quality checks.
