Performance analysis of a novel six-stroke Otto cycle engine

چکیده
In this study, a simulation model with finite time thermodynamics was presented for an Otto cycle six-stroke engine. engine, two free strokes occur after the exhaust stroke. These cause engine to have higher thermal efficiency. Due high efficiency, these engines can be used in hybrid electric vehicles. effect of residual gas fraction and stroke ratio on effective power efficiency were investigated. addition, heat balance obtained use fuel energy examined help performance fractions. model, results are quite realistic as working fluid assumed consist fuel-air-residual gases mixture.

متن کاملPerformance analysis a gas turbine cycle equipped with a double acting type stirling engine in a power generating unit
The aim of this study is to investigate the performance of a gas turbine cycle equipped with a Stirling engine from the thermodynamic point of view. In this system, part of the heat loss from the gas turbine is transmitted to a Stirling engine to generate more power. In the proposed system analysis, the governing equations of the hybrid cycle are modeled in MATLAB software and Schmidt and ideal...

متن کاملThe Quantum Harmonic Otto Cycle
The quantum Otto cycle serves as a bridge between the macroscopic world of heat engines and the quantum regime of thermal devices composed from a single element. We compile recent studies of the quantum Otto cycle with a harmonic oscillator as a working medium. This model has the advantage that it is analytically trackable. In addition, an experimental realization has been achieved, employing a...
