The discussion centers on the energy loss associated with the deceleration of a piston in an internal combustion engine, particularly at bottom dead center (BDC) and top dead center (TDC). Participants explore the implications of piston speed, the role of the flywheel, and the mechanics of energy transfer within the engine, with a focus on theoretical and practical aspects of engine design and efficiency.
Participants express differing views on the extent of energy loss during piston deceleration and the effectiveness of the flywheel and counterweights. There is no consensus on the implications of these factors, and the discussion remains unresolved with multiple competing perspectives.
Participants note limitations in the discussion, such as the need for specific calculations and theoretical models to quantify energy loss. The complexity of engine dynamics and the dependence on various design parameters are acknowledged but not fully explored.
This discussion may be of interest to those studying mechanical engineering, automotive design, or thermodynamics, particularly in relation to internal combustion engines and energy efficiency.
The issue here is that reciprocating internal combustion engine technology is extremely mature, having well over a century of technological progress and billions of production examples. This area is very well understood and there is an objectively right or wrong answer here. It's not up for a debate or an 'exchange of ideas' in the sense that you can just claim something and have an inherent right to have people seriously consider your idea. If you're going to propose something and then disagree when people correct you, please have a valid reference supporting you.JAlda333 said:I posted the topic for discussion. My goal is not to prove anyone wrong but to exchange ideas/views. If we do not openly share our thoughts, then there will be no discussion. Hopefully, we can all arrive on one conclusion. And if we still cannot agree, I will definitely not be the judge... but perhaps the readers may be able to. Thanks again.
