The invention relates to a SOx concentration detection device of the engine having a limiting current type sensor. The device of the invention comprises a detecting part for detecting the concentration of the SOx included in the exhaust gas by using an output current of the sensor while lowering a voltage applied to the sensor from a predetermined voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"SOx concentration detection device of internal combustion engine","description":"The object of the invention is to detect a concentration of a SOx included in an exhaust gas of an internal combustion engine easily and accurately by a limiting current type sensor.
