Construction machinery
First Claim
1. A construction machine comprising:
- a detecting means for measuring a fuel consumption ratio of the construction machine, said fuel consumption ratio being the fuel consumption per mechanical machine work done, andan indicating means for providing a first indication for communicating a difference between the measured fuel consumption ratio and a set fuel consumption ratio.

Abstract
Construction machinery is capable of prompting an operator to control or operate the machinery to improve fuel consumption. The fuel consumption per time or the fuel consumption per work amount is measured, and an image showing a difference between the measured fuel consumption per time and a set fuel consumption per time or between the measured fuel consumption per work amount and a set fuel consumption per work amount is displayed on a display device (30). When the measured fuel consumption per time is larger than the preset fuel consumption per time or the measured fuel consumption per work amount is larger than the set fuel consumption per work amount, an indication for prompting the operator to improve the fuel consumption is displayed on the display device (30).

19. A construction machine, comprising:
-
measurement means which measures a fuel consumption ratio; storage means which stores a plurality of reference fuel consumption ratios which are set in advance, corresponding to different work loads; selection means which selects the reference fuel consumption ratio which corresponds to the work load from the storage means; comparison means which compares the fuel consumption ratio measured by the measurement means and the reference fuel consumption ratio selected by the selection means; output means which outputs the result of comparison by the comparison means, and control means which has a plurality of selective work modes having respectively different reference load values, and controls an operation of the construction machine so that the work load thereof matches the reference load value corresponding to the selected work mode, wherein the storage means stores the reference fuel consumption ratios which correspond to the work modes; and the selection means selects the reference fuel consumption ratio which corresponds to the selected work mode.
