Title: Control device of internal combustion engine
Inventor: KAWACHI MASATO
IPC: F02D13/02
Filed: 2017-10-18
Abstract: To reduce unburned HC generated on a clevis when a catalyst is in an inactive state.SOLUTION: In a case where an inactive state of a catalyst is determined, a first exhaust port and a second exhaust port are opened in an exhaust stroke and an expansion stroke of the same cycle. In the expansion stroke, the second exhaust port is opened after the first exhaust port is closed. When only the first exhaust port is opened during an expansion stroke intermediate period, gas flow in a fixed direction generates in the combustion chamber. When only the second exhaust port is opened in an expansion stroke latter period thereafter, gas flow of a direction opposite to the gas flow in opening the first exhaust port, generates in the combustion chamber. Thus gas turbulence in each part of the combustion chamber is increased, and mixing of unburned HC generated on a clevis and oxygen is enhanced.SELECTED DRAWING: Figure 5
