Title: Exhaust gas purification system for hybrid engine and hybrid vehicle
Inventor: KIMURA KOICHI
IPC: B60L50/16
Filed: 2001-06-22
Abstract: PROBLEM TO BE SOLVED: To decrease the amount of air-polluting substances emitted into atmosphere from a hybrid engine. SOLUTION: A purification unit having the following configuration is mounted on a hybrid engine provided with an internal combustion engine and an electric motor. Namely, the purification unit is provided with: a purification catalyst that purifies air pollutants contained in exhaust emissions; a first exhaust passageway that allows an inflow of the exhaust emissions from one side of the purification catalyst; a second exhaust passageway that allows an inflow of the exhaust emissions from the other side of the purification catalyst; an exhaust passageway selector mechanism that selects either the first exhaust passageway or the second exhaust passageway; and a bypass passageway through which the exhaust emissions bypass the purification catalyst when the exhaust passageway is selected.  When the purification unit selects the exhaust passageway, operating conditions of the internal combustion engine are varied so as to decrease the amount of air-polluting substances emitted. This suppresses the amount of air-polluting substances that are not purified by the purification catalyst and that are discharged directly into the atmosphere together with the exhaust emissions through the bypass passageway when the exhaust passageway is selected.
