8-stroke low heat rejection engine

In a combustion engine, 25% of the energy present in the fuel is wasted as heat; this heat is dissipated to avoid overheating and prevent damages. This article presented a simulation work developed to study an internal combustion engine with a low heat rejection index. The engine is based on a 4-str...

description In a combustion engine, 25% of the energy present in the fuel is wasted as heat; this heat is dissipated to avoid overheating and prevent damages. This article presented a simulation work developed to study an internal combustion engine with a low heat rejection index. The engine is based on a 4-stroke cycle, but it reduces engine heat losses by extracting the heat absorbed by the walls during combustion and gas expansion; this reduces the need to dissipate heat through the cooling system. The engine can obtain more of the heat energy produced by the fuel than in conventional machines. This engine also works at higher temperatures than usual engines, thus promoting better combustion and emissions. Theoretical foundation and results obtained from a computational simulation are presented in this work.
