Abstract
A precombustion type diesel engine having a modified and improved flame cup and precombustion chamber arrangement wherein a single side-opening passage in the floor of the flame cup is provided with dual throats connecting with the prechamber. The primary opening or throat controls swirl development during gas inflow to the prechamber while the secondary opening or throat allows early discharge of initial combustion products to the main combustion chamber for improved secondary mixing and reduced particulate emissions.
