Abstract

The invention discloses an engineering vehicle, an engine oil consumption monitoring system and a method. Wherein, the engine oil consumption monitoring system includes: comprising: a first pressure obtaining device, which is used to obtain the first pressure value at the inlet of the control oil circuit of the hydraulic control valve in the hydraulic line connected between the engine and the oil pump; the second pressure obtaining device The device is used to obtain the second pressure value at the outlet of the executive oil circuit of the hydraulic control valve in the hydraulic line connected between the engine and the oil pump; the third pressure obtaining device is used to obtain the third pressure at the oil outlet of the oil pump value; a controller, configured to receive the first pressure value, the second pressure value and the third pressure value, and determine the fuel consumption of the engine according to the first pressure value, the second pressure value and the third pressure value. Compared with the existing power measurement system, the embodiment of the present invention can complete the measurement of engine oil consumption with three pressure sensors, the sensor type is single, and the arrangement is relatively simple.

Description

technical field

[0001] The invention relates to the field of engineering machinery, in particular to an engineering vehicle and an engine fuel consumption monitoring system and method. Background technique

[0002] At present, the fuel consumption of the engine is generally measured by arranging a fuel level sensor in the fuel tank, detecting the fuel remaining amount through the fuel level sensor, and then calculating the fuel consumption of the engine through the detected fuel remaining amount. This measurement method has high requirements for the installation of the fuel level sensor, and at the same time, the measured value is related to the vibration of the fuel tank and the temperature of the fuel, so there is a large error. Contents of the invention

[0003] In view of this, the present invention proposes an engineering vehicle and an engine fuel consumption monitoring system and method to solve the problem of high sensor installation requirements in existing engine...
