Embodiment 1

[0107] The first embodiment of the present invention will be described. figure 2 It is a diagram of the entire system. Such as figure 1 As shown, the fuel property discrimination system of this embodiment can be configured to include: construction work machine 10; management server 12 of network management department 11 set on the side of the construction work machine manufacturer; customer set on the side of leasing company 13 Server 14; and the communication network 17 connecting them together.

[0108] The communication network 17 includes: a satellite communication line connecting the construction machinery 10 and the satellite ground station 16 via a communication satellite 15; a dedicated ground communication line connecting the satellite ground station 16 and the management server 12 of the network management department 11; connecting the management server 12 and customers The internal network of the server 14 or a computer network such as the Internet. The purpose of usi...

Embodiment 2

[0154] Refer now Picture 10 The second embodiment will be described. In this embodiment, in the construction work machine 10, temperature correction and analysis of the measured value of the fuel property are performed. Picture 10 It is a process flow chart for executing the fuel property discrimination system of this embodiment.

[0155] When the construction work machine 10 removes the fuel cap 151 (S51: YES) and outputs a detection signal from the fuel property detection sensor 140 (S52: YES), the fuel property is measured (S53), and the measurement result is temperature-corrected (S54). Then, the construction work machine 10 (electronic controller 100) analyzes the composition ratio and the like of the fuel in the fuel tank 150 based on the temperature-corrected measurement value (S55).

[0156] The construction work machine 10 transmits the analysis result to the management server 12 (S56). In addition, the construction work machine 10 determines whether it is necessary to ...

Embodiment 3

[0161] Refer now Picture 11 The third embodiment will be described. In this embodiment, it can be diagnosed whether the fuel property detection sensor 140 is working normally. Picture 11 It is a flowchart for executing the fuel property discrimination system of this embodiment.

[0162] If the construction work machine 10 detects that the fuel filler cap 151 is removed based on the detection signal from the fuel filler cap sensor 143 (S71: YES), it is determined whether the fuel in the fuel tank 150 is increasing (S72).

[0163] When the remaining amount of fuel is increasing (S72: YES), the construction work machine 10 determines whether or not a detection signal is output from the fuel property detection sensor 140 (S73). When the detection signal is output from the fuel property detection sensor 140 (S73: YES), since the fuel property detection sensor 140 operates normally, the construction work machine 10 measures the fuel property (S74). The construction work machine 10 cre...

Abstract

The present invention relates to a system for discriminating the property of engineering operation mechanical fuel and a method thereof. The fuel property discrimination system, discriminating the fuel given to engineering operation machinery whether regular fuel or not, based on analysis of discrimination result to take appropriate control action. The fuel added from filler nozzle flow into fuel tank via fuel reception part. Before the prescribed measuring time ( filling time ), fuel property detection apparatus detect property of added fuel. Measured data is given by measuring data generation apparatus according to measurement result, residual fuel and ambient temperature. According to the measurement data, the measuring data analysis apparatus restrict output of engine, warning users, change evaluation of user.

Description

Technical field [0001] The invention relates to a system and a method for judging the fuel properties of engineering work machines. Background technique [0002] As construction work machines, various construction machines such as hydraulic excavators and wheel loaders, and transportation vehicles such as dump trucks are known. In order to reduce fuel costs, these construction machinery are equipped with diesel engines and use diesel as fuel. Most users of construction machinery use regular diesel, but there are cases where diesel is mixed with other fuels such as kerosene and used improperly. This is because kerosene is cheaper than diesel. [0003] However, in recent years, due to the strong demand from the society to take measures to deal with environmental problems, manufacturers of construction machinery and others have highly controlled diesel engines when designing major components to further reduce the impact on the environment. Carrying out this kind of high-level engine...
