Method and system for estimating injector fuel temperature
A fuel system for an engine is disclosed. The fuel system has a source of pressurized fuel, a plurality of fuel injectors, and a common manifold configured to distribute pressurized fuel from the source to the plurality of fuel injectors. The fuel system also has a first sensor located upstream of the common manifold, and a second sensor associated with the engine. The first sensor is configured to generate a first signal indicative of a fuel temperature. The second sensor is configured to generate a second signal indicative of a speed of the engine. The fuel system further has a controller in communication with the first and second sensors. The controller is configured to estimate a fuel temperature at each of the plurality of fuel injectors based on the first signal, the second signal, and the position of the plurality of fuel injectors along the common manifold.
