MANUFACTURING TECHNOLOGY Name Tutor Course College Date Automotive piston An automotive piston is one of the most important parts of an engine. Its function is to compress gasses that are within the combustion chamber or the combustion cylinder of an engine.
The fuel is then compressed and burnt after which it is expelled. Al the fuel is then moved through the cam or pop shaft, this is then moved to the gear and finally to the tires. An automotive piston that is found in the gasoline engine can withstand temperatures of up to 573K. There is a coolant that runs through the engine block and it always has a temperature of 363K. The piston must be cold when it is fixed into the cylinder. The piston can withstand high pressure of up to 10KPa inside the cylinder. It can withstand different atmospheres; it is able to do well in high latitude as well as low latitude. However in high humidity the engine uses less fuel as compared to low humidity. 1 There are several materials that can be used to make an automotive piston. Some of this include aluminum and copper alloys. The material to be used should be able to withstand high temperatures to start with. This is because the temperature of the engine is too high and so the material has to be able to withstand this without melting or having to expand a lot. The material also has to be able to withstand high pressure. A material that does not withstand high pressure cannot be used in the engine because of the high pressure that is experienced in the engine. Due to its high melting point and its ability to withstand high pressure and stress, the ideal material to be used is aluminum. ...
