2. Exhaust system - Wikipedia

   en.wikipedia.org/wiki/Exhaust_system

   Part of the pipe between the engine and the silencer is often flexible metal industrial ducting, which helps to avoid vibration from the engine being transferred into the exhaust system. Sometimes, a large diesel exhaust pipe is vertical to blow the hot, toxic gas well away from people; in such cases, the end of the exhaust pipe often has a ...

3. Diesel exhaust - Wikipedia

   en.wikipedia.org/wiki/Diesel_exhaust

Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...

4. Back pressure - Wikipedia

   en.wikipedia.org/wiki/Back_pressure

   Two similar pipings with same pressure distance and head. The second pipe contains some obstructions for flow resulting in less discharge. A common example of backpressure is that caused by the exhaust system (consisting of the exhaust manifold, catalytic converter, muffler and connecting pipes) of an automotive four-stroke engine, which has a negative effect on engine efficiency, resulting in ...

5. Tuned exhaust - Wikipedia

   en.wikipedia.org/wiki/Tuned_exhaust

   The pipe lengths and merging locations are designed to assist in filling the cylinder with the next intake charge using exhaust scavenging. [1] Locations where exhaust pipes from individual cylinders merge are called "collectors". The diameters of the exhaust system are designed to minimise back-pressure by optimising the gas velocity.
