An engine performance detection system and method for a heavy-duty transport vehicle

Abstract

The invention discloses a rapid engine performance detection system for a heavy duty truck and a method. A data acquisition sub system comprises a torque acquisition device which is mounted on a transmission shaft between a transmission case and a gearbox of a transmission system and is used for acquiring torque of a transmission shaft of a vehicle, a rotating speed acquisition device which is mounted on the transmission shaft between the transmission case and the gearbox of the transmission system and is used for acquiring a rotating speed of the transmission shaft of the vehicle, an oil consumption sensor which is connected in parallel with an oil pipeline between an oil case and an engine and is used for measuring real-time oil consumption amount of the engine, a throttle opening degree acquisition device which is mounted at a rotating shaft of a throttle opening degree pedal, realizes linkage along with the throttle opening degree pedal and is used for acquiring a throttle opening degree, and a gear acquisition device which is mounted on a gear lever and is used for acquiring a gear during a test. The detection system is advantaged in that engine performance detection can be rapidly carried out in real time, errors of the oil consumption sensor can be corrected by utilizing a rapid detection method, and measurement precision 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 system and method for detecting engine performance of a heavy-duty transport vehicle. Background technique [0002] The power unit is the power source of the heavy-duty vehicle equipment and the heart of the vehicle. Some basic technical performances of the heavy-duty vehicle equipment are directly or indirectly related to the relevant performance of the power unit. very important. [0003] The performance of the heavy-duty vehicle equipment power plant will decline with the increase of use time, especially the reduction of power performance will cause the heavy-duty vehicle equipment to reduce the maneuverability and affect the performance of its combat skills. Due to the shortage of monitoring equipment, troops cannot accurately Judging the degree of performance degradation of the power unit can only indirectly judge ...

AI Technical Summary

Problems solved by technology

Heavy-duty vehicles generally use mass-type fuel consumption sensors to measure fuel consumption, but there are two errors in mass-type fuel consumption sensors. One is that due to changes in the height of the oil level in the measuring cup in the measuring chamber, the reaction force of the buoyancy of the oil pipe extending under the liquid level in the measuring cup also changes, resulting in weighing The second is the measurement error caused by the fact that the device for measuring weight in the sensor is not kept level due to the driving of the vehicle
