SYSTEM AND METHOD FOR FUEL PUMP SHUTDOWN

The present disclosure provides systems and methods for fuel pump shutdown. Methods and systems for operating an engine including two fuel pumps are described. In one example, a first fuel pump may be activated or kept activated in response to an engine shutdown request, such that a second fuel pump may be cooled prior to deactivating the first fuel pump in response to the engine shutdown request. 本公开提供了"用于燃料泵关闭的系统和方法"。描述了用于操作包括两个燃料泵的发动机的方法和系统。在一个示例中，第一燃料泵可以响应于发动机停机请求而被激活或保持激活，使得第二燃料泵可以在响应于所述发动机停机请求而停用第一燃料泵之前被冷却。
