Modelling of a Conventional Piston of a Single Cylinder Four-Stroke Diesel Engine by Using SolidWorks

Abstract

This paper presents a 3D modelling of a conventional piston of a single cylinder four-stroke diesel engine using ZS1115NM diesel engine specification. Piston in internal combustion engine (ICE) is a circular piece of metal which converts the rotary movement of the crankshaft into reciprocating motion thereby exerting a force on the air-fuel mixture in the cylinder. It converts thermal energy into mechanical energy in an internal combustion engine (ICE). The methodology applied was analytical design and modelling of the piston using SOLIDWORKS 2013 3D Computer Aided Design (CAD) software. This method was used because it provided a step by step designing of the various elements of the piston. The material chosen for the piston is an aluminium alloy designated as A92618 or simply A2618, due majorly to its high coefficient of thermal expansion (CTE) which enables the piston withstand high thermal stress without cracking or failure.high thermal conductivity (approximately 3 times than that of cast iron). It is seen that with given engine specification a suitable material for designing a conventional piston is chosen and the model manufactured.
