Abstract (en)
[origin: WO2022199831A1] An air intake port (10) for a lean-burn gasoline engine (110) comprises an air inlet (14), two air outlets (15a, 15b), and an air channel connecting the air inlet (14) to the two air outlets (15a, 15b). The air channel comprises an upstream common duct (11) and two downstream port legs (12a, 12b), the two downstream port legs (12a, 12b) branching off from the common duct (11) at a bifurcation point (13). The upstream common duct (11) has a duct floor (42) and a duct ceiling (41), each comprising a sloped portion arranged to converge on the bifurcation point (13), wherein a bifurcation angle of less than 90 degrees is formed between the sloped portions of the duct floor (42) and the duct ceiling (41) at the bifurcation point (13).
