Embodiment Construction

[0025] Below in conjunction with embodiment, the present invention is further described, but does not constitute any restriction to the present invention, anyone makes the limited number of amendments in the scope of claims of the present invention, still within the scope of claims of the present invention.

[0026] The specific embodiment of the present invention is like this: with reference to Figure 1-Figure 8 As shown, an engine performance detection and comparison device includes a connecting assembly that is coaxially connected with the flywheel 1 and outputs torque to the outside. A sensor 2 that can transmit torque is coaxially installed on the connecting assembly. The matching processing device is coaxially installed on the outside of the sensor 2 with a drive shaft assembly that can be connected to the load. Connected to drive the load to rotate, the sensor 2 can detect the received torque, speed and other parameters, through the processing device for data analysis ...

Abstract

An engine performance testing and comparing apparatus, comprising a connecting component coaxially connected to a flywheel (1) and outputting a torque, a torque transferring sensor (2) coaxially mounted on the connecting component, a processing device provided at the periphery of the sensor (2) and paired with the sensor (2), and a load-connecting transmission shaft component coaxially mounted outside of the sensor (2). The engine performance testing and comparing apparatus is structurally reasonable, quick to mount, quick and accurate in testing, economical and practical, of a short assembled length, and structurally compact, effectively saves mounting space, allows stable and reliable torque transfer, and has high torque transfer efficiency.

Description

technical field [0001] The invention relates to the field of engines, more specifically, it relates to an engine performance detection and comparison device. Background technique [0002] In the performance test of the engine, the engine is connected to the dynamometer through the intermediate shaft, and the engine drives the main shaft of the dynamometer to rotate, so that the water in the vortex cavity of the dynamometer generates a vortex, and the brake of the dynamometer absorbs the output power of the engine. Passed to the sensor on the dynamometer, the dynamometer is equipped with a speed sensor, and the torque and power of the engine at a certain speed can be calculated. [0003] In the technical solution of the prior art, due to the water eddy current generated by the dynamometer, the water will generate heat, convert the input mechanical energy into heat energy, and consume a part of the input power, so there is a certain error. Contents of the invention [0004]...
