Abstract

The invention provides an engine external characteristic data adjusting method and device, equipment and a storage medium. The engine external characteristic data adjusting method comprises the stepsthat the current actual output torque corresponding to a current rotation speed point is obtained; according to a preset mapping relation between each rotation speed point and the maximum output torque, the maximum output torque corresponding to the current actual output torque is determined; the current actual output torque is compared with the corresponding maximum output torque, so that whetherthe current actual output torque meets the engine torque adjustment requirement or not is determined; if the engine torque adjustment requirement is met, the external characteristic torque correctionvalue corresponding to the current actual output torque is determined; according to the external characteristic torque correction value, the external characteristic torque of the engine is adjusted,so that the current actual output torque meets the engine delivery requirement. By the adoption of the engine external characteristic data adjusting method and device, the method for conducting spot check and adjustment of the external characteristic data of the engine is easy to operate, risk of misoperation is avoided, the efficiency of spot check and adjustment is greatly improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of engine test run, and in particular to a method, device, equipment and storage medium for adjusting external characteristic data of an engine. Background technique [0002] With the rapid development of manufacturing industry, the production of engines has also developed rapidly. Before the engine completes production and leaves the factory normally, a test run of the engine is required. An important link in the process of engine test run is the random inspection and adjustment of performance indicators. One of the important performance indicators of random inspection is whether the external characteristic data of the engine meet the requirements of the engine. The external characteristic data of the engine is the maximum required torque corresponding to each rotational speed point when the throttle is maximum. [0003] In the prior art, when determining whether the external ch...
