Abstract

A pre-combustion chamber system is presented. The pre-combustion chamber system includes a pre-combustion chamber housing defining a pre-combustion chamber, a cooling chamber housing surrounding the pre-combustion chamber housing, a cooling chamber defined between the pre-combustion chamber housing and the cooling chamber housing. The pre-combustion chamber system includes a flow agitator arranged in the pre-combustion chamber housing protruding into the pre-combustion chamber. The flow agitator increases flow disturbance in the pre-combustion chamber for improving mixture of fuel and air. Cooling of the pre-combustion chamber system is improved by dividing the cooling chamber into a cooling inner chamber and a cooling outlet chamber or by arranging cooling fins in the pre-combustion chamber housing extending into the cooling chamber.

Dependent claims

A pre-combustion chamber system comprising:

a pre-combustion chamber housing surrounding an interior cavity for defining a pre-combustion chamber;
a cooling chamber housing surrounding the pre-combustion chamber housing and sealed together with the pre-combustion chamber housing at two longitudinal ends forming a top portion and a bottom portion;
a cooling chamber defined between the pre-combustion chamber housing and the cooling chamber housing;
a flow agitator arranged in the pre-combustion chamber housing protruding into the pre-combustion chamber, wherein the flow agitator is configured to increase flow disturbance in the pre-combustion chamber;
and
a panel arranged between the pre-combustion chamber housing and the cooling chamber housing, wherein the panel is configured to divide the cooling chamber into a cooling inlet chamber and a cooling outlet chamber, wherein the panel is sealed together with the pre-combustion chamber housing and the cooling chamber housing at the top portion, wherein the panel leaves an opening at a bottom of the cooling chamber, and wherein the cooling inlet chamber and the cooling outlet chamber communicate with each other through the opening at the bottom of the cooling chamber.
