Cold Start Improvements With a Heat Store 910305

The Heat Battery, a latent heat store, accumulates waste heat of the engine and preserves it by efficient heat insulation. On the next cold start, after a day or a weekend, the heat is released with an initial power of 50 to 100 kW.
This energizes the vehicle heating system within seconds, allowing for hot air to flow instantly to the cabin and to the windshield. The passenger comfort is immediately felt, and the windshield can be defrosted or demisted without manual help.
Due to the high heating power the engine will warm up within 30 seconds so that the tailpipe emissions of carbon monoxide are reduced up to 50% and unburnt hydrocarbons up to 30% in the first bag of the CVS-Test.
