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.
