Abstract: A fuel delivery system of a machine capable of efficiently feeding fuel, where a time of feeding fuel to a construction machine is estimated based on operation information of the construction machine. Based on position information of the construction machine acquired by position information acquiring means and estimated time of feeding fuel, a delivery schedule, which has a short moving distance and capable of delivering and feeding fuel efficiently in a short period of time, is formed. The delivery schedule is notified to a controller of the construction machine. The delivery schedule is reconstructed by a set input of a change in the delivery schedule from the controller. A specified form for requesting expense of feeding fuel is automatically formed from a fuel feeding amount after fuel has been delivered and fed by the formed delivery schedule and confirming to feed fuel.

Abstract: A management system of a machine equipped with a driving-power source reads out maintenance conditions from a storage means of maintenance management information when data and conditions, concerned about a maintenance management of a machine, the features of the machine, and so on, including the maintenance conditions, are inputted from the input means. Then, information about predicted maintenance management under a certain operation time of the machine is predicted with reference to the maintenance conditions. Subsequently, the information about the predicted maintenance management is represented on a display means. Furthermore, a maintenance predicted value is previously stored in a data base or the like with respect to the maintenance within an operation time under the contract or within a contract term for each of a plurality of contract ranks. A maintenance actual result value of the machine being entered is accumulatively stored.

Abstract: To provide a fuel delivery system of a machine capable of efficiently feeding fuel, time of feeding fuel to a construction machine is estimated based on operation information of the construction machine acquired by operation information acquiring means and remaining amount information of fuel acquired by fuel remaining amount information acquiring means of a server. Based on position information of the construction machine acquired by position information acquiring means of the server and estimated time of feeding fuel, a delivery schedule having a short moving distance and capable of delivering and feeding fuel efficiently in a short period of time, is formed. The delivery schedule is notified to a controller of the construction machine. The delivery schedule is reconstructed by a set input of a change in the delivery schedule from the controller.

Abstract: The present invention relates to a water pump for an internal combustion engine, capable of effectively preventing the entry of dust into a bearing for an impeller shaft, and of providing a simply constructed and small-sized dustproof function. To this end, a fan (32) is mounted on a portion of an impeller shaft (18) which is positioned within a cup-shaped hood (30), and the inflow of dust into the bearings (22F, 22R) is prevented by the fan (32). The hood (30) is provided with blowout holes (44) in the portions thereof which are opposed to the outer circumference of the fan (32).

Abstract: According to the present invention, a power transmission apparatus for an internal combustion engine (2) having a supercharger (1) attached thereto is constructed such that thermal energy included in exhaust gas discharged from a turbine (T) in the supercharger is recovered by a waste heat recovering turbine (3) thereby to drive the waste heat recovering turbine (3), auxiliary units (9), (10) for a cooling system of the internal combustion engine (2) are driven by power generated by the waste heat recovering turbine (3) which has been driven and the power generated by the wasted heat recovering turbine (3) is then transmitted to a crankshaft (12) of the internal combustion engine (2) via a coupling (6) for interrupting power transmission in an operational region where the internal combustion engine is rotated at a low speed or in an operational region where the internal combustion engine is rotated under a low load.
