Title:
INTERNAL COMBUSTION ENGINE WITH FAST COMBUSTION AND METHOD FOR CONTROLLING INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2022125010
Kind Code:
A
Abstract:
To provide an innovative solution for an internal combustion engine which is characterized by both high operating efficiency and an extremely simple structure.SOLUTION: An engine includes at least one cylinder, and a first intake valve and a second intake valve that control flows of intake air from a first intake duct and a second intake duct, respectively. The two intake ducts communicate with a common intake manifold so as to receive air at the same pressure. During the intake stage, in each cylinder operating cycle, initially an opening and closing movement of only the first intake valve is activated while the second intake valve remains closed, and subsequently an opening and closing movement of only the second intake valve is activated while the first intake valve remains closed. In this way, the two air flows at the same pressure entering the cylinder give rise to a high turbulent kinetic energy (TKE), to the advantage of combustion efficiency and reduction of harmful exhaust emissions.SELECTED DRAWING: Figure 4
