Liquid cooled fuel injection valve and method of operating a liquid cooled fuel injection valve |
摘要 |
A liquid cooled fuel injection valve is operable to inject fuel directly into a combustion chamber through a nozzle orifice provided in an injector tip. The fuel injection valve further comprises a cooling system for draining fuel from a fuel cavity disposed within the injector tip and a drain valve that opens when pressure within the fuel cavity is greater than a predetermined set point. Fuel drained through the cooling system is directed to a drain system that may be combined with drain passages typically found in fuel injection valves. In a preferred embodiment, the drain valve is disposed within the fuel injection valve. |
