Divided chamber diesel combustion system

摘要

A combustion system for a divided chamber engine that incorporates a pre-combustion chamber disposed to one side of the cylinder and that communicates with the main combustion chamber through two diverging transfer passages the open ends of which are aimed to direct the discharge from the pre-combustion chamber towards the sides of the combustion chamber and not at the center of the piston or the exhaust valve wherein the localized temperature at the piston's center is reduced and the exhaust valve temperature is not elevated.
