  • optimisation of a model internal Combustion Engine with linear phenomenological heat transfer law
    International journal of ambient energy, 2010
    Co-Authors: Lingen Chen, Hanjiang Song, Fengrui Sun
    Abstract:

    SYNOPSIS The optimal motion of a model internal Combustion Engine with a piston fitted inside a cylinder containing an ideal gas is examined. The gas is heated at a given rate f(t) and coupled to a heat bath with linear phenomenological heat transfer law q ∝ Δ(T−1) for a finite amount of time. The optimal motion of the model internal Combustion Engine with linear phenomenological heat transfer law and maximum power output objective is obtained, as well as the optimal motion of the model internal Combustion Engine with linear phenomenological heat transfer law, fixed power output and maximum useful work output objective. The maximum useful work output per cycle, the maximum power output and the corresponding efficiency are obtained. Numerical examples are provided and the obtained results are compared with those obtained with Newton's heat transfer law. The results presented herein can provide the basis for both determination of optimal operating conditions and design of real systems operating with linear ...

  • Optimisation of a model external Combustion Engine with linear phenomenological heat transfer law
    Journal of the Energy Institute, 2009

    Abstract:

    Abstract The optimal motion of a model external Combustion Engine with a piston fitted inside a cylinder containing an ideal gas is examined. The gas is heated at a given rate f(t) and coupled to a heat bath with linear phenomenological heat transfer law q∝Δ(T –1) for a finite amount of time. The optimal motion of the model external Combustion Engine with maximum power output objective is comprised of fully cyclic operation and semicyclic operation. The maximum work output per cycle and the corresponding efficiency are obtained respectively. Furthermore, the finite optimal compression ratio of such Engine with special working condition is obtained. Numerical examples are provided, and the obtained results are compared with those obtained with Newton's heat transfer law. The results presented herein can provide the basis for both determination of optimal operating conditions and design of real systems operating with the linear phenomenological heat transfer law.

  • hydrogen fueled internal Combustion Engine
    Progress in Energy and Combustion Science, 2009
    Co-Authors: Tomohiro Shinagawa, Takashi Atsumi
    Abstract:

    The present invention relates to a system that is capable of freely selecting one or two or more types of fuel and supplying the selected types of fuel to an internal Combustion Engine. Disclosed is a hydrogen-fueled internal Combustion Engine that operates upon receipt of one or more types of fuel that are selected from hydrogenated fuel and a dehydrogenated product and hydrogen, which are obtained by dehydrogenating the hydrogenated fuel. The hydrogen-fueled internal Combustion Engine comprises: a hydrogenated fuel storage section; reaction means for invoking a dehydrogenation reaction; separation means for separating hydrogen-rich gas and dehydrogenated product; and a dehydrogenated product storage section for storing the separated dehydrogenated product.

  • the hydrogen fueled internal Combustion Engine a technical review
    International Journal of Hydrogen Energy, 2006
    Co-Authors: Christopher White, Richard R. Steeper, Andrew E. Lutz
    Abstract:

    A review is given of contemporary research on the hydrogen-fueled internal Combustion Engine. The emphasis is on light- to medium-duty Engine research. We first describe hydrogen-Engine fundamentals by examining the Engine-specific properties of hydrogen and surveying the existing literature. Here it will be shown that, due to low volumetric efficiencies and frequent preignition Combustion events, the power densities of premixed or port-fuel-injected hydrogen Engines are diminished relative to gasoline-fueled Engines. Significant progress has been made in the development of advanced hydrogen Engines with improved power densities. We discuss several examples and their salient features. Finally, we consider the overall progress made and provide suggestions for future work.
