Abstract

The invention provides a method and a device for testing the effective thermal efficiency of an engine. The method comprises the following steps: acquiring oil consumption data, rotating speed data and torque percentage data collected by the engine at each sampling moment in a preset time period; and according to the oil consumption data, the rotating speed data and the torque percentage data, the effective heat efficiency of the engine in the preset time period is determined. According to the method and the device for testing the effective thermal efficiency of the engine, the fuel consumption data, the rotating speed data and the torque percentage data of the engine are acquired in the preset time period, the effective thermal efficiency of the engine in different working states can be accurately calculated based on the data, and the effective thermal efficiency of the engine can be accurately tested in different working states. The online real-time test of the effective thermal efficiency of the whole-vehicle-level engine is realized.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a method and device for testing the effective thermal efficiency of an engine. Background technique [0002] The effective thermal efficiency is one of the important indicators to measure the economic performance of the engine and the whole machine. By accurately testing the effective thermal efficiency of the engine under various working conditions of the construction machinery, and studying the characteristics of the engine and its matching with the construction machinery, it is not only possible to evaluate the engine and the whole machine It can provide a basis for the correct selection of engines for construction machinery. At the same time, through the analysis of various factors affecting engine fuel consumption, technical measures to improve the characteristics of the engine to meet the matching requirements can be proposed to optimize the performance of the...
