Abstract
An exhaust system includes a reverse flow heat exchanger having a plate separating an intake chamber and an exit chamber, each chamber having an inlet and an outlet located at opposing ends to allow flow therethrough. The plate can include a vane connected to the end of the plate in the vicinity of an inlet or an outlet. The vane is configured to reduce resistance to fluid flow near the intake chamber inlet. The exhaust system includes a heating manifold, such as a combustion chamber, configured to receive an exhaust stream from the intake chamber, further heat the exhaust stream, and return the exhaust stream to the exit chamber. Embodiments of the system can be configured to additionally perform as a catalytic converter and/or a muffler.
Claims27
An exhaust system comprising:
- an engine configured to propel a vehicle and to produce exhaust gas;
- a first exhaust manifold configured to receive exhaust gas from the engine;
- a reverse flow heat exchanger coupled to the first exhaust manifold, the reverse flow heat exchanger including a plate defining a plane and separating an exit chamber and an intake chamber, the intake chamber having an intake chamber inlet and an intake chamber outlet located at opposing ends to allow flow therethrough, the exit chamber having an exit chamber inlet and an exit chamber outlet, the intake chamber inlet in fluid communication with the first exhaust manifold and configured to receive exhaust gas from the first exhaust manifold, the intake chamber outlet configured to communicate exhaust gas to the exit chamber inlet and;
- a vane within the first exhaust manifold disposed relative to the intake chamber inlet so as to reduce resistance to fluid flow near the intake chamber inlet.
A vehicle exhaust system comprising:
- an exhaust manifold configured to receive exhaust gas from an internal combustion engine;
- and
- a reverse flow heat exchanger coupled to the exhaust manifold, the reverse flow heat exchanger including
- a transverse plane, and
- a plurality of parallel plates separating a number of chambers, the chambers comprising a set of intake chambers alternating with a set of exit chambers, each intake chamber having an inlet and an outlet and each exit chamber having an inlet and an outlet, the inlets of the intake chambers being in fluid communication with the exhaust manifold and configured to receive exhaust gas from the exhaust manifold and the outlets of the intake chambers being in fluid communication with the inlets of the exit chambers and configured to communicate exhaust gas to the inlets of the exit chambers.
A vehicle comprising:
- an internal combustion engine;
- and
- an exhaust system configured to receive exhaust gas from the internal combustion engine and to remove particles from exhaust gas, the exhaust system including
- an exhaust manifold and
- a reverse flow heat exchanger coupled to the exhaust manifold and including a plurality of parallel plates separating a number of chambers, the chambers comprising a set of intake chambers alternating with a set of exit chambers, each intake chamber having an inlet and an outlet, each exit chamber having an inlet and an outlet, the inlets of the intake chambers being in fluid communication with the exhaust manifold and configured to receive exhaust gas from the exhaust manifold and the outlets of the intake chambers being in fluid communication with the inlets of the exit chambers and configured to communicate exhaust gas to the inlets of the exit chambers.
