To provide a piston for a prechamber-type gas engine and a prechamber-type gas engine taking into consideration the shape of the piston top surface portion so that the region where flame propagation due to torch jet is delayed, a piston for a prechamber-ty...

The pre-chamber system (1) has a pre-chamber volume (4) including an ignition region (3) and a flow transfer region (7) separated from each other by an intermediate wall (9). A flow transfer passage (5) connects the flow transfer region of the pre-chamber ...

A pre-combustion chamber tip (76) of an internal combustion engine (10) exposed to high thermal and mechanical stress may be limited in space for arranging orifices (190, 290) fluidly communicating with a main combustion chamber (26) of the internal combus...

Disclosed are an adiabatic engine, an engine capable of reusing exhausted energy, and a high pressure jet assembly. The adiabatic engine has: a cylinder (10) having an inner side surface, on which the adiabatic member (12) is formed extending longer than a...
