COMBUSTION CHAMBER SYSTEM OF ENGINE

摘要

An internal combustion piston engine has a prechamber or auxiliary chamber associated with each main combustion chamber and connected thereto by a plurality of torch openings. Ignition of a relatively rich mixture in the auxiliary chamber causes flames to be projected through the torch openings to ignite the relatively lean mixture in the main combustion chamber. A plurality of torch openings are provided between the auxiliary combustion chamber and the main combustion chamber and are positioned such that they direct torch flame both toward the valves in the main combustion chamber as well as towards the region of the main combustion chamber remote from the valves.
