Device and method for monitoring engine power performance of a heavy-duty vehicle

Abstract

The invention discloses a device and method for monitoring engine power performance of a heavy vehicle.The device comprises a data acquisition sub-system; the data acquisition sub-system comprises a torque acquisition device, a rotation speed acquisition device, a fuel consumption acquisition device, an accelerator opening acquisition device and a gear acquisition device, wherein the torque acquisition device is mounted on a transmission shaft between a transmission case and a gearbox in a transmission system and used for acquiring the torque of the transmission shaft of the vehicle; the rotation speed acquisition device is mounted the transmission shaft between the transmission case and the gearbox in the transmission system and used for acquiring the rotation speed of the transmission shaft of the vehicle; the fuel consumption acquisition device comprises a fuel inlet sensor and a fuel return sensor, the fuel inlet sensor is mounted at a fuel inlet of a fuel filter, the fuel return sensor is mounted on a fuel return line of a fuel injection pump, and the fuel consumption acquisition device acquires real-time fuel consumption of an engine; the accelerator opening acquisition device is mounted at a rotating shaft of an accelerator opening step plate and is in linkage with the accelerator opening step plate and used for acquiring accelerator opening; the gear acquisition device is mounted on a gear shift lever and acquires the gear during a test.By means of the performance detection device, changes of the technical condition of a power device are monitored in real time, and timeliness of equipment guarantee is improved.

Description

technical field [0001] The invention relates to the field of performance detection of heavy vehicles. More specifically, the present invention relates to a device and method for monitoring engine power performance of a heavy vehicle. Background technique [0002] The power unit is the power source of the armored equipment and the heart of the vehicle. Some basic technical performances of the armored equipment are directly or indirectly related to the relevant performance of the power unit. Therefore, the performance detection of the power unit is crucial to the performance of the vehicle. important. [0003] The performance of armored equipment power units will decline with the increase of use time, especially the reduction of power performance will cause the reduction of armored equipment's maneuverability and affect its combat performance, and the troops cannot accurately judge due to the shortage of monitoring equipment. The degree of performance degradation of the powe...

AI Technical Summary

Problems solved by technology

The performance of the armored vehicle's power plant cannot be monitored in real time, which will affect its training, combat, postponement of service, and even accidental failure (damage) due to incorrect use

In addition, the detection system can also be used as a test instrument for field tests of armored equipment to carry out real vehicle testing of power plants, solving the problem of lack of experimental equipment for field real vehicle tests
