Abstract
A machine includes an internal combustion engine mounted on a chassis and having an intake manifold. An air intake system extends from an air inlet to the intake manifold and includes a condensate collection location. The machine also includes a liquid system having a pump that is mechanically coupled to the internal combustion engine. A drain valve is positioned in the air intake system at the condensate collection location and includes a valve member having a closed position and an open position. In the closed position of the valve member, a closing surface of the valve member is exposed to pressurized liquid within the liquid system and the condensate collection location is fluidly blocked from a discharge opening in the air intake system. In the open position of the valve member, the condensate collection location is fluidly connected to the discharge opening.
