Future exhaust emissions standards, such as Euro VII, are expected to introduce significantly stricter requirements for pollutant emissions. Today’s emissions aftertreatment systems function excellently at exhaust-gas temperatures above 200°C. However, during operating periods when exhaust temperatures are below this threshold, the pollutant conversion capabilities of the catalytic converters will be insufficient to meet future emissions standards. The eHeater developed by HJS cuts the length of such low-temperature periods by converting electrical energy from the vehicle’s electrical system to thermal energy that is then used to heat the exhaust gases.
