Title:
METHOD AND DEVICE FOR EXECUTING FUNCTIONAL TEST OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS58131533
Kind Code:
A
Abstract:
The invention relates to a process and apparatus for carrying out function tests on internal combustion engines using the idle-acceleration method. In such a test, the engine is subjected to at least one acceleration cycle, in a condition of being disconnected from the load. The various moments of inertia of the engine, including clutch plates and flywheel, cause effective loading on the engine. In this way loading cycles may be simulated by varying the positive or negative acceleration value. The invention now proposes a preparation cycle before the actual test cycle. During the preparation cycle, the acceleration values which depend on the individual engine power output are measured and the actual test cycle is corrected in dependence on the result of the measurement operation, in such a way that the predetermined acceleration values and thus also the loading values are maintained.
