Discussion Overview
The discussion centers around the feasibility of eliminating lubrication in an internal combustion hydrogen engine by using magnetic levitation to separate engine parts. Participants explore the technical challenges and implications of this concept, including the necessary voltage and current to achieve such levitation.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant proposes using a magnetic field to keep engine parts separated, potentially eliminating the need for lubrication.
- Another participant expresses skepticism about the suitability of internal combustion engines for this application, citing the need for sealing to prevent combustion product escape and the complexity of engine motion.
- A participant seeks to further develop their idea and asks if they can post additional questions and diagrams related to the design challenges posed by a hydrogen engine.
- One participant agrees that a seal would be necessary, implying that lubrication would still be required to prevent excessive wear.
- Another participant mentions that while magnetic levitation has been tried in rotating machinery, the varying loads in a piston engine present greater challenges.
- A participant suggests that the Wankel engine might be better suited for the proposed concept of using magnetic levitation.
Areas of Agreement / Disagreement
Participants express differing views on the feasibility of using magnetic levitation in internal combustion engines, with some supporting the idea while others highlight significant challenges and limitations. The discussion remains unresolved regarding the practicality of the proposed concept.
Contextual Notes
Participants note the need for sealing in internal combustion engines and the complications arising from varying loads in piston engines, which may affect the viability of magnetic levitation as a lubrication alternative.
