The assembly frame 60 protrudes more than the fuel cell apparatus group 61, toward the radiator 11 at the front side. The fuel cell assembly 12 is installed in the front room 10 such that a height of a front edge part A of the assembly frame 60 at a front side approximately matches a height of a center of gravity P of the entire fuel cell assembly 12.

A fuel control system obtains a measured amount of fuel consumed by an engine and one or more corresponding operating parameters of the engine and determines a fuel consumption modeled amount based at least in part on a fuel consumption model of the engine and the one or more operating parameters. The fuel consumption model associates different amounts of fuel that, when supplied to the engine, generate corresponding designated outputs of the engine. The system also determines one or more differentials between the measured amount of fuel and the modeled amount and, responsive to the one or more of the differentials exceeding a threshold value, the system identifies one or more components of the powered system that contribute or cause the one or more differentials and/or changes an amount of fuel supplied to the engine according to the fuel consumption model to obtain a desired output of the engine.
