A1
Abstract:
A small-sized diesel engine. An EGR valve (4) is provided in an EGR gas flow path (3), and an exhaust gas flow divider (5) is provided in an exhaust gas route (1). The exhaust gas flow divider (5) divides exhaust gas (6) into a flow of high PM concentration gas (7) and a flow of low PM concentration gas (8) that have different concentrations of particle matter, and the high PM concentration gas (7) is used as an EGR gas (9). Preferably, an exhaust gas flow dividing and swirling path having a helical shape is provided in the exhaust gas flow divider (5), so that the exhaust gas (6) swirls by energy of the exhaust gas itself in the exhaust gas flow dividing and swirling path.
