Fuel injection system for diesel-internal combustion engine, has temperature sensor detecting fuel temperature in flow pipe, and controller controlling delivery rate of low pressure fuel pump based on fuel temperature detected by sensor

摘要

The system (10) has a high pressure-fuel pump (18) comprising a high pressure outlet (24) and a fuel inlet (20) connected with an outlet of a low pressure fuel pump (14). A fuel return line (22) is connected with a fuel tank (12) over a fuel return-flow pipe (46). A temperature sensor (60) is arranged such that the sensor detects fuel temperature in the fuel return-flow pipe. A controller (56) controls delivery rate of the low pressure fuel pump based on the fuel temperature detected by the temperature sensor. A pressure sensor (54) is connected with a high pressure fuel storage (38). An independent claim is also included for a method for operating a fuel injection system for an internal combustion engine.
