ADIABATIC SPARK-PLUG Russian patent published in 2011 - IPC F02B23/02 H01T13/00 

FIELD: engines and pumps.

SUBSTANCE: ignition system of energy carrier of combustion engine contains a groove and support that during piston movement towards cylinder head provide pressure increase between them till energy carrier flash-point temperature in the space between groove and support. Mating groove and support are performed as projecting into combustion chamber and they can interact at piston movement towards cylinder head. Groove space is equipped with channels that connect it with over-piston space. The support in a form of a solid cylinder is installed at the thread along piston axis. The groove is performed in a form of cylinder with open cylindrical cavity and installed by thread into cylinder head coaxially the support and equipped with radially directed cylindrical and conical channels.

EFFECT: structure simplification, improvement of combustion process and increase of ignition system safety, extension of ignition zone that allows working with low and highly enriched mixtures improving engine start and operation at inaccurate adjustment of carburettor.
