Abstract

See full text

A work machine evaluates the fuel consumption for the whole engine running period including the time of operation and the time of non-operation of a work implement and informs an operator of the evaluation in real time to prompt fuel-consumption-savings. The work machine has an engine, a hydraulic pump driven by the engine, an actuator driven by a hydraulic fluid delivered by the hydraulic pump, and an operation device that operates the actuator. A display apparatus for the work machine includes a fuel consumption index calculating section that calculates a first fuel consumption index by dividing the operation time of the operation device by the fuel consumption amount of the engine or dividing the fuel consumption amount of the engine by the operation time of the operation device. The first fuel consumption index calculated by the fuel consumption index calculating section is displayed on a display section in real time.
