FUEL PROPERTY DETECTION APPARATUS FOR CONSTRUCTION MACHINE

摘要

Provided is an apparatus for detecting property of fuel in a construction machine, with use of a sub-tank, the apparatus being capable of minimizing an influence on the detection given by water contained in fuel. The apparatus includes a sub-tank between an engine and a fuel tank of the construction machine, a fuel introducing pipe through which fuel is introduced to the sub-tank from the fuel tank, a fuel discharger through which fuel in the sub-tank is discharged to the engine, and a sensor. The sub-tank has a bottom section having a bottom fuel outlet for discharging fuel from the bottom section. The fuel discharger includes a bottom fuel discharging pipe connected to the bottom fuel outlet.
