The system provides a means to discharge and treat the exhaust gas from the engine. It should do this without exhibiting vibrations that are transmitted to the vehicle structure and manifest themselves as NVH (noise, vibration, and harshness) issues.
A system of components that directs burned gases from the engine, to the rear of the vehicle, and out into the atmosphere. Typical components of the exhaust system include the exhaust manifold (bolted to the engine), exhaust pipes (connecting the exhaust components to each other), and exhaust muffler (the device that reduces the engine exhaust noise). All vehicles built since 1988 (and most built since 1975) also have a catalytic converter in the exhaust. The catalytic converter is the only component of the exhaust system that reduces harmful emissions (the oxygen sensor is attached to the exhaust system but is not generally considered to be a part of the exhaust system).
This system conducts the exhaust gases from the exhaust manifold to the rear of the car and into the air. Component such as catalytic converters and mufflers help reduce pollution causing elements and loud noises along the way out.
The exhaust system consists of the exhaust manifold, exhaust pipe, catalytic converter, muffler and tailpipe. The system performs three important jobs: it carries exhaust gases away from the engine, it quiets the engine (See Muffler), and it helps control
An exhaust system conveys burnt gases from an internal combustion engine and typically includes a collection of exhaust pipes. In the most basic sense, the exhaust system simply vents waste gases from the engine. Depending on the overall system design, the exhaust gas may flow through a turbocharger to increase engine power, a catalytic converter to reduce air pollution, and a muffler to reduce noise.
