Full working condition passage-separated and time-separated supercharged intake internal combustion engine variable compression ratio technology

摘要

Passage-separated intake of the present invention refers to that a separate supercharged intake passage and a separate supercharged intake supply apparatus are provided such that natural intake is separated from supercharged intake to implement respective intake without mutual interference. Time-separated intake refers to that in order to avoid a cylinder C from becoming a passage between natural intake and supercharged intake, natural intake is performed first in an intake stroke, and supercharged intake is performed after a bottom dead center of the intake stroke at the end of the natural intake.
