Design Analysis and Optimization of a Four Stroke Single Cylinder Diesel Engine Piston
A piston is a component of reciprocating engines reciprocating pumps gas compressors and pneumatic cylinders among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas tight by piston rings In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/ or connecting rod In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder wall. The petrol enters inside the cylinder and the piston moves upwards and the spark plug produces spark and the petrol is set on fire and it produces an energy that pushes the piston downwards A four stroke engine (also known as four cycles) is an internal combustion (IC) engine in which the piston completes four separate strokes while turning a crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. According to the present scenario the automobile sector is adopting new trends in technologies in safety of the passengers and in the reduction of cost by increasing the performance of the vehicle. So in order to increase the performance of the engine the design analysis and optimization of a four stroke single cylinder diesel engine piston is considered for even cost reduction. The complete design and analysis of the engine is done by using CATIA V5. Optimization is done by reducing the mass of the material and by using best suitable material satisfying the properties of the piston.
