ABSTRACT:
An intake and exhaust system for use with lean-burn combustion engines includes a first intake port and a second intake port that transfer a fuel-air mixture to a combustion chamber within a cylinder. At least one exhaust port allows combustion gases to exit the combustion chamber. Preferably, in the intake and exhaust system, a first exhaust port and a second exhaust port are located on diagonally opposite sides of the cylinder. The first intake port preferably transfers a fuel-air mixture to the combustion chamber in a direction opposite of the second intake port. When two exhaust ports are used, it is preferable that the first exhaust port transfers gas outside of the combustion chamber in a direction opposite of the second exhaust port. The location of the input and exhaust ports creates a strong swirl under a range of loads.
