A throttleable exhaust venturi is described herein that generates strong suction pressures at an exhaust outlet by accelerating an incoming ambient fluid stream with the aid of a venturi to high gas velocities and injecting a combustion exhaust stream into the ambient fluid stream at an effective venturi throat. A mixing element downstream of the venturi throat ensures that the mixed fluid stream recovers from a negative static pressure up to local atmospheric pressure. A physical and the effective throat of the venturi are designed to promote mixing and stabilize the ambient fluid flow to ensure that high velocity is achieved and the effective venturi is operable over a variety of combustion exhaust stream mass flow rates. |

An extendible exhaust system is disclosed for preventing exhaust gas seepage into the passenger compartment of a vehicle utilizing a pipe extender that slides along the tailpipe. The pipe extender has a retracted position and an extended position. The pipe extender moves from the retracted position to the extended position when the vehicle travels forward at a predetermined speed. When in the extended position, exhaust flows through the additional length of the pipe extender before exiting the exhaust system. Movement of the pipe extender from the retracted to the extended position may be by airflow traveling past the moving vehicle pushing on a flange acting as a sail against a tension spring. An electromagnet or motor drive system with a movement sensor may also be used to move the pipe extender from the retracted to the extended position. |

The exhaust tube system also includes a center brace having dimensions which span the length and height of the sideways openings. The sideways openings of the first and second half-shells are coupled together around the center brace to form a flattened elongate exhaust tube having an inlet end and an outlet end for directing exhaust gases from the internal combustion engine. In one aspect the first and second half-shells are selected from a group of interchangeable and modular half-shells having different substantially U-shaped cross-sectional profiles that are reversible top-to-bottom and end-to-end. |
