Contrasting Hot Cold testing technique's for I.C Engine's

摘要

It is imperative to test the functionality of an engine prior to installing in a vehicle. A hot test system is a 100% production test used to check all the engine operating parameters as they would function real-time in an actual vehicle whereas a cold test consists of a leak test, which includes the testing of all cavities and systems that must not leak, such as oil, water, fuel and air. The second feature of a cold test procedure is dynamic cold testing; where all engine functions are tested while the engine is driven by an electric motor at various speeds. In this study, co-relation is drawn between both the techniques with the present fault finding methods in cold testing and its subsequent enhancements which leads to refining the manufacturing or assembly processes.
