Preheating components with metal hydrides or lime – Small, high power, no additional energy

Operation temperature of vehicle components in internal combustion engines is far above ambient temperature, in particular compared to winter ambient temperatures of down to -20 °C. At the cold start phase at the beginning of a driving cycle, the systems’ performance is highly inefficient, which leads to increased pollutants (NOx, CO, HC) and degradation of the components. 60-80% of all pollutants of the whole driving cycle are generated during this cold start phase. It takes several minutes until the system reaches operation temperature.
