Automotive exhaust system

Abstract

The automotive exhaust system includes a plurality of exhaust pipes that feed into a common collector. The collector includes a venturi at the point where the exhaust gases enter the collector from the multiple exhaust pipes. The exhaust gases accelerate through the venturi by virtue that the venturi has a cross-sectional area smaller than that of the exhaust pipes and the collector. A plurality of vanes located in the venturi further accelerate the exhaust gases into a spinning vortex along the interior surface of the main body of the collector to efficiently and quickly expel the exhaust gases out from within the automotive exhaust system. The diameter of the venturi relative to the collector is specific to each diameter of tubing as matched with the corresponding vehicle specifications.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to an automotive exhaust system. More particularly, the invention relates to an automotive exhaust system having an improved collector that accelerates the expulsion exhaust gases out the tailpipe.[0002]Over the years, various exhaust systems have been designed to improve the efficiency and power output of four-stroke internal combustion (“IC”) engines. Improvements in engine components and “super tuning,” as is more typically done in racing systems, have produced significant increases in engine power, especially with respect to the exhaust system. The efficiency of expelling exhaust gases resultant from the combustion process in an IC engine is important to the overall efficiency of the engine. For example, increasing exhaust system efficiency can reduce fuel consumption of the IC engine while maintaining and improving output power.[0003]The exhaust gases in an IC engine exit the piston cylinder chamber through an exhau...

Benefits of technology

[0008]The improved automotive exhaust system of the present invention includes a plurality of exhaust pipes at the proximal end that join into a common collector at the distal end. The collector includes a venturi at the point of entry of the exhaust gases from the multiple exhaust pipes. The venturi has a cross-sectional area smaller than that of the cross-sectional area of the pipes or the cross-sectional area of the main body of the connector. In turn, exhaust

Problems solved by technology

This directly affects vehicle performance, fuel consumption, efficiency and power.

Any exhaust gases remaining in the exhaust system may have a tendency to stagnate or even reverse direction due to a change in vacuum.

Ultimately, this force may exert back pressure on the piston, thereby preventing efficient escape of the exhaust gases from within the cylinder.

Additional power is wasted if the piston has to push against t
