Abstract
Abstract An intake and exhaust flow improvement device for internal combustion engines is disclosed. The invention provides an anti-reversion chamber having a gas-redirecting profile on the intake side as well as providing a gas-redirecting profile on the exhaust side. The device also provides for toroidal loops placed within the exhaust and intake manifolds to have a swirling flow-enhancing effect by which the intake charge is continued to be held ready for the next opening of the intake valve and whereby the exhaust gases are smoothly exited from the exhaust manifold by providing a loop pathway to continue the one-way energy of the exhaust gases.
