Intake reservoir for an engine having a check valve

Patent ·
OSTI ID:5128132
This patent describes an intake reservoir for an engine having an intake passage leading to a cylinder, a check valve in the intake passage to allow fluid flow toward the cylinder and obstruct fluid backflow in the reverse direction, an intake valve seated in the intake passage between the check valve and cylinder, and a bypass port located on the intake passage so that the bypass port communicates with a trapped volume defined by the portion of the intake passage between the check valve and intake valve. It comprises a reservoir cavity having a single cavity port, a port passage connected between the cavity port and the bypass port enabling fluid flow between the trapped volume and the reservoir cavity, and a control valve connected to the port passage enabling active adjustment of the flow area of the port passage throughout a range of engine operating conditions to regulate fluid flow between the trapped volume and the reservoir cavity.
