Design analysis of a piston for compressed natural gas (CNG) engine

Engine pistons are one of the most complex components among all automotive or other industry field components. The engine can be called the heart of a car and the piston may be considered the most important part of an engine. There are lots of research works proposing for engine pistons, new geometr...
