An exhaust system associated with a power source is disclosed. The exhaust system may have an exhaust stack extending from the power source to an exterior of the exhaust system and a moisture collection device disposed within the exhaust stack to collect moisture from the exhaust stack. The exhaust system may also have a moisture entrainment device associated with the moisture collection device to facilitate entrainment of the collected moisture into an exhaust flow of the power source.

A system and method is provided for automatically priming a fuel system by bleeding/purging air or vapor therefrom. The system includes a bleed valve configured to automatically move between three positions in response to the pressure of the fuel in the system. When fuel pressure is in a first pressure range, the bleed valve automatically moves to a first-closed position for preventing fuel from draining to the fuel tank and thereby drawing air into the fuel system. When the fuel pressure moves to a second, higher pressure range, the bleed valve automatically moves to an open position for bleeding air out of the fuel system and into the tank, thereby priming the fuel system. When the fuel pressure moves to a third, still higher pressure range, the bleed valve automatically moves to a second-closed position so as to not interfere with the regulation of the pressure regulating valve.

Air laden with oil and blow-by gases is evacuated from an engine compartment such as a crankcase. The air is cleaned by removing oil and may be reused for engine combustion by routing it through a turbocharger inlet. The reclaimed oil may be returned to an oil pan for reuse in engine lubrication.
