The difficulty in designing internal combustion piston is determined by complex operating conditions. Piston is the busiest engine part. Combined mechanical and thermal loads work on it. Profiling the piston in two mutually perpendicular planes is a major part of its design. The shape of the piston in a cold state is quite different from the cylindrical one. The aim is, despite the varying amount of material in the various zones, when the working temperature reaches the piston to take cylindrical form, thus providing minimal clearance to the engine cylinder. Because it is a moving part, the parameters at work are hard to determine. There are studies of the piston temperature state, some of which are described and analysed. |
