More Information
Summary:A condensed liquid outlet port 50, 70 is provided at the lowest point of the gas inlet passage of an i.c. engine 12. The intake air may pass through a cooler, eg an intercooler 24 and a small (eg 0.5mm diameter) orifice 50, fig. 1, may be provided beneath the cooler allowing condensation products, eg water, to escape while minimizing loss of intake air. The water may be discharged or may be fed to a container or tray. Alternatively, the outlet port may be in the inlet manifold 14. The intake passage may receive exhaust gases from an EGR system having an EGR cooler 40 and the outlet port 70, fig.2, may be connected to the exhaust system 30 by drain passage(s) 72-78 which terminate upstream of, or between, exhaust after-treatment devices 32-36. An orifice 50 as in fig.1 may also be provided.
