HYDROGEN FLAME ARRESTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18119655 titled 'HYDROGEN FLAME ARRESTOR
In an internal combustion engine, a flame arrestor is disclosed for insertion into intake runners of the intake manifold to prevent backfires.
- The flame arrestor comprises at least two substrates separated by an internal air gap of 3-9 millimeters.
- Each substrate consists of a metallic mesh with channels, with one substrate having unaligned channels with the other.
- The internal air gap and unaligned channels effectively quench backfires into the intake runners.
Potential Applications: - Automotive industry for internal combustion engines - Industrial machinery with internal combustion engines
Problems Solved: - Preventing backfires in internal combustion engines - Ensuring safety and efficiency in engine operation
Benefits: - Improved engine performance - Enhanced safety measures - Reduced risk of damage to the intake manifold
Commercial Applications: Flame arrestors can be used in various vehicles and machinery with internal combustion engines to enhance safety and prevent backfires.
Questions about Flame Arrestors: 1. How do flame arrestors improve engine safety?
- Flame arrestors prevent backfires from causing damage to the intake manifold, ensuring safe engine operation.
2. What are the key features of a flame arrestor?
- A flame arrestor consists of substrates with metallic mesh and channels, separated by an internal air gap to quench backfires effectively.
Original Abstract Submitted
In an internal combustion engine, the use of natural gas containing hydrocarbon or hydrogen may result in backfires into the intake manifold. Thus, a flame arrestor is disclosed for insertion into intake runners of the intake manifold. The flame arrestor may comprise at least two substrates, separated by an internal air gap of 3-9 millimeters (e.g., substantially 4 millimeters). The substrates may each comprise a metallic mesh with channels. The channel of one substrate may be unaligned with the channels of the other substrate. The internal air gap and/or unaligned channels of the disclosed flame arrestor effectively quench backfires into the intake runners.
