- Abstract
In this research work an attempt has been made to investigate the scavenging performance of a novel spark ignited two stroke free piston engine with spring system using three different spring materials as a rebound device. Free piston engines do not have a conventional crank shaft. The connecting rod of the free piston engine is fixed rigidly to the piston and the other end is attached to the spring. FPE with linear generator has been identified as novel technology for hybrid vehicle. The objective of the work is to analyze the scavenging performance to optimize important parameters namely geometry of spring and material of spring. 3D model of engine has been simulated for the combustion process to identify the scavenging efficiency by using spring pressure. Computational fluid dynamic analysis is carried out by varying the parameters to find out better scavenging efficiency in order to achieve fuel economy. The optimum of scavenging efficiency was seen for the free piston engine employed with chrome vanadium alloy steel spring.
