Abstract

The invention discloses a system and a method for monitoring oil consumption of an engineering vehicle and an engine. The system for monitoring the oil consumption of the engine comprises a first pressure acquiring device, a second pressure acquiring device, a third pressure acquiring device and a controller, wherein the first pressure acquiring device is used for acquiring a first pressure value of an inlet of a control oil circuit of a hydraulic control valve in a hydraulic pipeline connected between the engine and an oil pump; the second pressure acquiring device is used for acquiring a second pressure value of an outlet of an executing oil circuit of the hydraulic control valve in the hydraulic pipe connected between the engine and the oil pump; the third pressure acquiring device is used for acquiring a third pressure value of an oil outlet of the oil pump; and the controller is used for receiving the first pressure value, the second pressure value and the third pressure value and determining the oil consumption of the engine according to the first pressure value, the second pressure value and the third pressure value. Compared with the conventional power measuring system, the system for monitoring the oil consumption of the engine in an embodiment has the advantages that the oil consumption of the engine can be measured by the three pressure sensors, and the sensors are single in type and simple in arrangement mode.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a construction vehicle and an engine fuel consumption monitoring system and method. Background technique [0002] At present, the fuel consumption measurement of the engine is generally by arranging the fuel level sensor in the fuel tank, detecting the remaining fuel quantity through the fuel level sensor, and then calculating the fuel consumption of the engine through the detected fuel remaining quantity. This measurement method has high requirements on the installation of the oil level sensor, and the measurement value is related to the vibration of the fuel tank and the fuel temperature, and there is a large error. SUMMARY OF THE INVENTION [0003] In view of this, the present invention proposes an engineering vehicle and an engine fuel consumption monitoring system and method, so as to solve the problem of high requirements for sensor installation in the existing engin...
