Owing to the stricter legislation in the USA, the engines for the US market have an OBD concept "pressure sensor". With a differential pressure sensor in the tank ventilation system and the hot film air mass meter, leaks in the crankcase ventilation, tank ventilation, as well as the blow-by lines can be identified. Via a feed-in point at the exhaust turbocharger the blow-by gases are fed back into the clean air line of the air intake system.
