Claims

[Scope of utility model registration request]

In a diesel engine, the combustion chamber is equipped with an approximately spherical pre-combustion chamber that communicates with the combustion chamber through a nozzle at the top of the cylinder.
A subchamber structure for a diesel engine, characterized in that a protrusion is formed at the bottom of the subchamber to divert the fuel jet in order to expand the fuel jet within the subchamber.
