TRAP DEVICE FOR PREVENTING FLAME OF INTERNAL COMBUSTION ENGINE

摘要

A trap device for preventing the flame of an internal combustion engine is provided to reduce the amount and the impact of flame emitted outside by maximizing flame heat absorbing space with a first escape duct and a second flame escape duct. A trap device for preventing the flame of an internal combustion engine comprises: first and second flame escape ducts(10,30) absorbing flame through escape holes(10b,30b) formed between straps(10a,30a); a decompression diffusion space(20) reducing the pressure of the flame which becomes weak through the first flame escape duct; and a plurality of flame heat absorbing nets(40) absorbing the flame flowed into the decompression diffusion space. The first and second flame escape ducts are installed at the circumference of an opening of a crankcase in which flame is emitted. The second flame escape duct is installed at the outside of the decompression diffusion space. The flame heat absorbing net is installed inside the decompression diffusion space.
