ABSTRACT:
An intermittent bypass system comprises an intake conduit including an intake passage leading to a cylinder in an engine and an intake controller connected to the intake passage adjacent to the cylinder. The intake controller enables, during different portions of the engine cycle, fluid flow from the intake passage into the cylinder, fluid back-flow from the cylinder into the intake passage, and obstruction of fluid flow between the intake passage and the cylinder. A check valve is located in the intake passage upstream of the intake controller with the check valve allowing fluid flow toward the cylinder and obstructing fluid back-flow in the reverse direction. A bypass port is located on the intake passage to provide a flow path to a downstream portion defined by the portion of the intake passage between the check valve and intake controller. A control valve is connected between a secondary fluid source and the bypass port enabling communication between the secondary fluid source and downstream portion during a portion of the engine cycle when the check valve is open. The control valve obstructs the communication during a portion of the engine cycle when the check valve is closed.
