Diesel engine test method

Abstract

A diesel engine test method comprises the following steps: (A) program-controlled running-in of the diesel engine; (B) program-controlled test of the diesel engine. The running-in sequence of the diesel engine is optimized to avoid operation stop of the diesel engine in the test process; the test sequence and the test time of the diesel engine are optimized to reduce the test cost and improve the work efficiency. The diesel engine is pre-adjusted in the test process to reduce the test steps; the diesel engine performance is pre-adjusted in the program-controlled running-in stage and the program-controlled test stage of the diesel engine to save energy, reduce emission and improve productivity. A diesel engine test process verification means is established to simulate the running state of a whole vehicle to solve the problem of poor power performance of the whole vehicle, and can realize 100% timely verification of the test quality of Deutz diesel engines while lowering the maintenance cost. A diesel engine speed controller database is established to unify the position of diesel speed controller function limit screws; the speed controller is simplified from a complex trail state to a standardized table lookup, thereby solving the technical difficulty in adjusting the diesel engine performance.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a test method for diesel engines. Background technique [0002] The process of running-in test with the power generated by the diesel engine itself is usually called hot test. It is to check whether the diesel engine has reached the proper assembly performance, and at the same time, it is used for the engine to run and close before the car runs, so as to ensure the normal use of the engine. Large diesel engines have high requirements on parameters and performance. Hot test has become the last key process in the production process, which plays a very important role in the quality of diesel engine manufacturing. The main content is to record and Analyze and judge whether it is qualified or not, and can detect and eliminate faults in time. [0003] At present, the gradually warming global climate and the increasingly depleted oil resources are directly related to the emissi...
