Abstract
An internal combustion engine includes a combustion chamber, a chamber portion, and a communication passage for communicating the combustion chamber to the chamber portion. A valve for opening/closing the passage allows a high compression gas to be charged into the chamber portion and an air-fuel mixture to be injected from the chamber portion into the combustion chamber. A lubricating system keeps the opening of the passage to the combustion chamber and a surface of a piston facing to the opening well lubricated. The lubricating system includes an oil supply hole opening in a same direction as the opening of the passage to the combustion chamber. The oil supply hole may be positioned under the opening of the passage, or may be provided between a lower edge of the opening of the passage and a piston ring of the piston, when the piston is located at a bottom dead center.
