Abstract (en)
[origin: WO2013037542A1] The invention relates to a high-pressure fuel pump (5) for an injection system of a combustion engine, having a pump housing (16), and a pump piston (14) which is guided in a pump cylinder and can be moved up and down by translation, wherein a temperature sensor (22) is provided for determining the temperature of the fuel conveyed by the high-pressure fuel pump (5). According to the invention, a high-pressure fuel pump (5) having increased robustness is provided. This is achieved by arranging the temperature sensor (22) in the area of the high-pressure fuel pump (5). In particular, the pump piston (14) is moved by a plunger (17) which is guided in a receptacle (13) and delimits an upper plunger space (20) in said receptacle, and the temperature sensor (22) is arranged in the area of the upper plunger space (20) or of a connecting line (21) between two upper plunger spaces (20). The temperature detected by the temperature sensor (22) is preferably used for controlling a low pressure pump (2) and thus for regulating the cooling of the high-pressure fuel pump (5).
