Abstract
An air bypass system for an internal combustion engine is provided. The internal combustion engine includes an air intake system defining a first air intake chamber and a second air intake chamber coupled in flow communication with the first air intake chamber. The air bypass system includes at least one bypass assembly controlling flow communication between the first air intake chamber and the second air intake chamber, said at least one bypass assembly facilitating air flow from the second air intake chamber into the first air intake chamber during an expansion stroke of the internal combustion engine.
Claims6
An apparatus for use in an internal combustion engine having a piston supported in a bore for reciprocal motion including a compression stroke and an expansion stroke, the apparatus comprising:
- an air intake system configured to deliver air to the bore in the cylinder, including a first air intake chamber, a second air intake chamber between the first air intake chamber and the bore, and a one-way valve operative between the first and second air intake chambers, wherein the one way valve permits air to flow through the one way valve only in a direction from the first air intake chamber to the second air intake chamber;
- wherein the air intake system further includes a bypass assembly including a two way valve which, in a closed condition, blocks air flow between the first air intake chamber and the second air intake chamber through the two way valve and, in an open condition, permits air flow between the first air intake chamber and the second air intake chamber through the two way valve.
