A survival belt buckle configured to be worn around the user's waist that may make a fire under different environmental conditions. The belt buckle includes a rigid body made of high carbon steel. The body includes a plurality of striking points that when stuck against a flint, chert rock, or quartz produces a spark to ignite dry tinder or other combustible material. On a perimeter edge of the body is a ferrocerium rod that can be used with a steel knife or stone to produce spark. Also, on a perimeter edge of the body is a magnesium bar that produces small shavings that can be ignited. Also, in the rigid body is a magnifying lens used to ignite tinder with sun rays. The belt buckle is waterproof, easily transported and can be use with a knife, hard stone, other metal pieces, or with similar belt buckles worn by others.

An internal combustion engine with a piston having a piston head with a resonance cavity opening onto the head, and where a fuel nozzle located in a cylinder head is positioned to inject a fuel such as natural gas into the combustion chamber where resonance formed within the resonance cavity will ignite the fuel without the need of a spark plug. Inlet and exhaust ports in the cylinder head allow for air and combustion gas enter or leave the combustion chamber.

A push-button type flint ignition mechanism that is capable of automatic reset, including: a built-in flint, a grinding wheel abutting the flint, an energy storage member that stores energy through deformation, a driving wheel rotating in the same direction as the grinding wheel when the energy storage member releases energy, a wheel axle about which the driving wheel rotates, a driving body pushed by the energy storage member when the energy storage member releases energy, a plucking portion located on the driving body and capable of plucking the driving wheel to make the driving wheel rotate, a blocking member capable of blocking the movement of the driving body, a moving member capable of making linear movements back and forth inside the mechanism and capable of squeezing the energy storage member to cause elastic deformation in the latter, and a reset member capable of pushing the moving member to reset; wherein, when no external force is exerted on the mechanism, the projections of the plucking portion and the driving wheel, respectively onto the plane perpendicular to the direction of movement by the moving member, do not overlap. Moreover, and optionally, when the energy storage member finishes releasing energy, the projections of the plucking portion and the driving wheel, respectively onto the plane perpendicular to the direction of movement by the moving member, do not overlap.
