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.
