Title: | Efficiency of a new internal combustion engine concept with variable piston motion | Authors: | Dorić, Jovan Klinar I. |
Issue Date: | 14-Mar-2014 | Journal: | Thermal Science | Abstract: | This paper presents simulation of working process in a new internal combustion engine concept. The main feature of this new internal combustion engine concept is the realization of variable movement of the piston. With this unconventional piston movement it is easy to provide variable compression ratio, variable displacement and combustion during constant volume. These advantages over standard piston mechanism are achieved through synthesis of the two pairs of non-circular gears. Presented mechanism is designed to obtain a specific motion law which provides better fuel consumption of internal combustion engines. For this paper Ricardo/WAVE software was used, which provides a fully integrated treatment of time-dependent fluid dynamics and thermodynamics by means of 1-D formulation. The results obtained herein include the efficiency characteristic of this new heat engine concept. The results show that combustion during constant volume, variable compression ratio and variable displacement have significant impact on improvement of fuel consumption. | URI: | https://open.uns.ac.rs/handle/123456789/7283 | ISSN: | 3549836 | DOI: | 10.2298/TSCI110923020D |
