Measurement of contaminant components in exhaust gas and reduction of excessive contaminant emissions during cold starts and while driving

摘要

This invention pertains to the emission control in motor vehicles but also in ships, airplanes and diesel locomotives. The control system may either be fitted into new vehicles by the manufacturer or be retrofitted by the driver in older vehicles. An adsorption system serves to reduce the vehicle emissions during the cold-start period, in case of malfunctions in the engine or in the exhaust gas after-treatment system and in times of high quantities of pollutants in the atmosphere. To regenerate the adsorbent masses, the pollutants will be desorbed, introduced into the combustion chamber and burned.
