Title:
AUXILIARY CHAMBER-TYPE INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2020/196684
Kind Code:
A1
Abstract:
In this auxiliary chamber-type internal combustion engine, by moving a closing wall relative to a partition wall of an auxiliary chamber in response to progress of the intake, compression, expansion and exhaust strokes, the opening area of a communication passage is changed, and the opening area of the communication passage in the exhaust stroke and the intake stroke is widened to be greater than the opening area of the communication passage in the compression stroke and the expansion stroke. The partition wall has two communication passages of different cross-sectional areas. The closing wall carries out the relative movement, closing the one communication passage while exposing the other communication passage. In this way, the communication passage opening area changes.
