なる副室式エンジンの燃焼室。In the auxiliary chamber nozzle, which is composed of a main nozzle and at least one auxiliary nozzle that communicate the main combustion chamber and the auxiliary combustion chamber, the outflow angle from the main combustion chamber to the main combustion chamber and the inflow angle from the auxiliary combustion chamber to the main auxiliary nozzle are respectively θ1. When expressed as θ2, θ has a relationship such that θ2, and furthermore, the outflow angle from the auxiliary nozzle to the main combustion chamber located outward from the cylinder center line B-B with respect to the open end of the main nozzle is, θ1. A combustion chamber of a pre-chamber engine has a relationship of θ11>θ1 when expressed as θ11>θ1.
