摘要： Methods and systems are provided for operating a vehicle including an engine and a fuel system. In one embodiment, a water drainage system for a fuel system comprises a fuel tank, a fuel-water separator, a separator water sensor, a drain valve, a purge tank, a purge tank water sensor, and a purge port. The fuel tank is in fluid communication with the fuel-water separator which is in fluid communication with the fuel-water separator which is in fluid communication with the drain valve which is in fluid communication with the purge tank. The purge tank is enclosed within and in fluid communication with the fuel tank. The separator water sensor may be operably disposed in the fuel-water separator and the purge tank water sensor may be operably coupled to the purge tank. The purge port is in fluid communication with the purge tank.

摘要： A system for automated water drainage in a fuel system includes a fuel-water separator, a water sensor, first and second drain valves, a drain pressure sensor, and a control system, which is operably connected to the first and second drain valves, the water sensor, and the drain pressure sensor. The water sensor is disposed in the fuel-water separator for detecting the presence of water. The first drain valve is in fluid communication with the fuel-water separator, and the second drain valve is in fluid communication with the first drain valve; a fluid duct connects the first and second drain valves. The drain pressure sensor is positioned in the fluid duct, for detecting pressure levels in the fluid duct. The control system automatically operates the first and second drain valves, for removing purge liquid from the fuel-water separator, based on signal outputs of the water sensor and the drain pressure sensor.
