1. An apparatus comprising:
- a charge air cooling chamber, the cooling chamber having a lower wall with an orifice in the lower wall;
a condensate pipe that is fluidly connected to drain condensate from the orifice into a collection tank;
a vent pipe that is fluidly connected to vent fumes from an upper opening of the collection tank to an exhaust stack; and
a loop seal that is fluidly connected to drain the condensate from a lower opening of the collection tank.

Abstract
A charge air cooling chamber has a lower wall with an orifice in the lower wall. A condensate pipe is fluidly connected to drain exhaust fume condensate from the orifice into a collection tank. A vent pipe is fluidly connected to vent fumes from an upper opening of the collection tank to an exhaust stack. A loop seal is fluidly connected to drain condensate from a lower opening of the collection tank. Exhaust gas moisture condensate drains from the cooling chamber into the collection tank, via the continuously open orifice. Exhaust gas moisture condensate fumes vent from the collection tank to the exhaust stack.
