Method and device for exhaust gas management

Abstract

A system and method for increasing the performance of an internal combustion engine having a stock exhaust manifold. An exhaust insert affixed to or positioned downstream from the cylinder exhaust ports, in the exhaust conduits, in the stock manifold, in the collector, before or after the catalytic converter, before or after any Y-pipe, or any location in the exhaust system. The exhaust insert having a pre-determined size and shape to optimize performance, including, but not limited to, fuel efficiency, emissions, and power.

Description

TECHNICAL FIELD[0001]Exemplary embodiments of the invention relate to exhaust system inserts from internal combustion engines (e.g., gasoline, diesel, biodiesel, compressed natural gas, alcohol, ethanol, and other similar combustion engines). More particularly, exemplary embodiments relate to the placement of an insert into an original manufacturers exhaust system of an internal combustion engine in order to improve engine performance, including, but not limited to, fuel efficiency, emissions control, and power.BACKGROUND[0002]The performance and efficiency of internal combustion engines depends on the efficient movement of gases through the engine, from the introduction of air and fuel through the intake ports into the cylinders of the engine to exhaust of the combustion by-products through the exhaust ports. The exhaust system performs a critical role in this process and has a significant impact on efficiency of the engine. The exhaust system operates to provide complete and effic...

Problems solved by technology

While exhaust inserts were used to increase horsepower in race cars with headers specifically designed for inclusion of an exhaust insert it was believed, by those skilled in the art, that exhaust inserts would produce detrimental results when applied to stock exhaust systems.

Those of ordinary skill in the art cited several reasons including throttle conditions, differing computer systems and the physical length of racing headers which are much longer and tuned differently from stock exhaust manifolds for the expectation that exhaust inserts would produce a detrimental effect on stock exhaust systems.

Those of ordinary skill in the art believed insertion of an exhaust insert would cause poor engine performance and result
