Abstract: Provided is a configuration which prevents an engine from being unable to start in the state in which dew condensation occurred in a fuel injection pump and froze. The present invention relates to a fuel injection pump which is provided with a pump body and a hydraulic head and driven by an engine, and is characterized in that while the engine is in operation, the temperature of the hydraulic head is increased to a dew-point temperature or higher. Consequently, it is possible to increase the temperature of the hydraulic head and remove water in the fuel injection pump while the engine is in operation. Accordingly, the engine can be prevented from being unable to start in the state that dew condensation occurred in the fuel injection pump and froze.

Abstract: 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).

Abstract: A fuel pressure sensor/ sensor mount assembly for use in a fuel injection system equipped with fuel injectors which inject fuel, as supplied from an accumulator (CL) through fuel pipes (50), into a multi-cylinder internal combustion engine mounted in an engine compartment of a vehicle. The assembly includes a connector unit (70) and fuel pressure sensors (60). The connector unit (60) has formed therein a plurality of communication paths (70a) each of which is to establish a connection between one of the fuel injectors and the accumulator (CL) through one of the fuel pipes (50). The connector unit (60) also has formed therein sensor mounts exposed to the communication paths (70a). Each of the fuel pressure sensors (60) is disposed in the sensor mount to measure the pressure of the fuel in the communication path (70a). This structure permits steps of installing the fuel pressure sensors within the engine compartment to be decreased and ensures desired measurement accuracy of the fuel pressure sensors (60).
