Problems solved by technology

[0008] ②Weighing method Due to the limited capacity of the metering fuel tank, the time for measuring fuel consumption is limited, so it cannot be continuously measured for a long time;
[0009] ③Due to the large fuel consumption of high-power diesel engines, the capacity of the measuring fuel tank is large, the size of the weight detector is large, the measurement accuracy is reduced, and it takes up a lot of space, so it is not suitable for on-board measurement
[0010] ④During the diesel engine test run, the ground vibration will affect the measurement accuracy

Embodiment 1

[0049]This embodiment is applied to the measurement of the fuel consumption of the diesel engine during the test run of the diesel engine platform. The diesel engine test platform requires a relatively large site and a long oil transmission line, so the fuel circulation line is also long, and the diesel cycle in the fuel circuit requires relatively high pressure, which requires multiple pressurization of the fuel in the cycle.

[0050] Please refer to Fig. 2, Fig. 2 is a schematic diagram of a measuring device using a single mass flow meter in the fuel consumption measuring device of a diesel engine according to the present invention. It can be seen from the figure that the diesel engine fuel consumption measurement device using a single mass flowmeter consists of fuel oil tank 1→fuel supply pump 2→first mass flow meter 3→circulation pump 5→diesel engine 6→fuel oil tank 1 to form a large main fuel oil tank. circuit. The electrical signal output by the first mass flow meter 3 ...

Embodiment 2

[0064] This embodiment is applied to the measurement of fuel consumption of diesel engines on ships. This embodiment and embodiment 1 are similar technical solutions based on the same invention purpose, but they cannot replace each other, and each has its own advantages.

[0065] Please refer to Fig. 3, Fig. 3 is a schematic diagram of a measuring device using dual mass flowmeters in the fuel consumption measuring device of a diesel engine according to the present invention. As can be seen from the figure, the diesel engine fuel consumption measurement device in the present invention includes fuel oil tank 1→fuel supply pump 2→circulation pump 5→first mass flow meter 3→diesel engine 6→second mass flow meter 12→fuel oil tank 1 composed of a large fuel circuit. The electrical signals output by the first mass flow meter 3 and the second mass flow meter 12 are respectively connected to different input ports of the fuel consumption meter 4 through wires.

Abstract

The invention relates to a diesel engine fuel consumption measurement device, and the device installs mass flow meter on the original fuel system, and transmits the signals of the mass flow meter output and the signals of the original diesel engine output power to the fuel oil consumption device to conduct operations, and outputs the diesel engine output power, fuel consumption volume and fuel consumption rate. The diesel engine fuel consumption measurement device of the invention greatly enhances the measurement precision, and it can real-time monitor the diesel fuel consumption status, applied to the diesel on the land or water.

Description

technical field [0001] The invention relates to a diesel engine, in particular to a diesel engine fuel consumption measuring device. Background technique [0002] Before the diesel engine products leave the factory, the fuel consumption index of the diesel engine must be provided. The method of measuring the fuel consumption index of the diesel engine in the prior art generally adopts the method of weighing. Weight counter composition. The measurement feature of the system is to directly measure the weight change of the fuel stored in the fuel metering tank to determine the fuel consumption. The advantage of this is that the weight data can be obtained directly without temperature compensation and weight conversion. [0003] Fig. 1 is a schematic structural diagram of a system for measuring fuel consumption of a diesel engine by weighing method in the prior art. It can be seen from the figure that the main structure of the system for measuring diesel engine fuel consumpti...
