Lubrication Systems and Methods of Lubrication used in IC Engine! Introduction to Lubrication in I.C. Engine: The machine parts which have relative motion rub against each other. The rubbing surfaces are never perfectly smooth, even when they are highly polished. If they are observed under a microscope, small depressions and elevations can be seen. These depressions and elevations get interlocked [...]
In this article we will discuss about the Otto Cycle and Diesel Cycle of IC engine. The question arises of these engines, which are most efficient and what are the factors that impose limitation on the maximum efficiency. Sadi Carnot was the first scientist to study this problem and he found that the maximum possible efficiency of an engine, working [...]
The testing of I.C. Engines is the process of assessing the performance and operation of the engine in the efficient manner. There are various parameters which can be measured for testing of I.C. Engines. The testing of the engine is necessary for understanding the efficient operation of the engine and the engine components. The operation of the new engine depends [...]
