Fuel Nature Discriminating System for Working Machines, and Fuel Nature Discriminating Method for Working Machines

摘要

The fuel nature discriminating system of the present invention discriminates whether or not a fuel fed to a working machine is the normal one, and performs appropriate control operation by analyzing the result of discrimination. The fuel fed from a fuel supply nozzle flows into a fuel tank through a fuel catching portion. Fuel nature detecting means measures the nature of the fed fuel at a predetermined timing (or at the time of refueling). Measured data generating means generates measured data on the basis of the measurement result and also the remaining amount of fuel and the environmental temperature. And, in accordance with the result of analysis of the measured data, a measured data analyzing means executes restriction of the engine output, issues a warning to the user, and alteration of an evaluation of the user.
