Intake reservoir system for an engine having a check valve
Patent
·
OSTI ID:5199047
This patent describes an intake reservoir system 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 back-flow in the reverse direction, and a bypass port located on the intake passage. The bypass port communicate with a trapped volume defined by the portion of the intake passage between the check valve and cylinder. The intake reservoir system comprises inflow means for enabling fluid to flow into the trapped volume when the pressure therein is at least equal to the pressure upstream of the check valve. The intake reservoir system further comprises a reservoir cavity, a port passage connected between the reservoir cavity and the bypass port enabling communication between the reservoir cavity and the trapped volume, and a volume control means enabling adjustment of the volume of the reservoir cavity.
