  2. Exhaust gas recirculation - Wikipedia

    en.wikipedia.org/wiki/Exhaust_gas_recirculation

    In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1] EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. The exhaust gas displaces atmospheric air and reduces O 2 in ...

  3. Exhaust heat recovery system - Wikipedia

    en.wikipedia.org/wiki/Exhaust_heat_recovery_system

    Exhaust heat recovery system. An exhaust heat recovery system turns waste heat energy in exhaust gases into electric energy for batteries or mechanical energy reintroduced on the crankshaft. The technology is of increasing interest as car and heavy-duty vehicle manufacturers continue to increase efficiency, saving fuel and reducing emissions.

  4. Diesel exhaust - Wikipedia

    en.wikipedia.org/wiki/Diesel_exhaust

    Diesel exhaust is the gaseous exhaust produced by a diesel type of internal combustion engine, plus any contained particulates. Its composition may vary with the fuel type or 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 ...

  5. Heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Heat_exchanger

    Heat exchanger. A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. [1] The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. [2]

  6. Cummins X-series engine - Wikipedia

    en.wikipedia.org/wiki/Cummins_X-series_engine

    The Cummins X-series engine is an Inline (Straight)-6 diesel engine produced by Cummins for heavy duty trucks and motorcoaches, replacing the N14 in 2001 when emissions regulations passed by the EPA made the engine obsolete. Originally called the "Signature" series engine, the ISX uses the "Intellect System" (hence the "IS" which is the moniker ...

  7. Exhaust system - Wikipedia

    en.wikipedia.org/wiki/Exhaust_system

    Exhaust heat management helps reduce exhaust heat radiating from the exhaust pipe and components. One dominant solution to aftermarket upgrades is the use of a ceramic coating applied via thermal spraying as a heat shield. This not only reduces heat loss and lessens back pressure, but also provides an effective way to protect the exhaust system ...

  8. Exhaust gas - Wikipedia

    en.wikipedia.org/wiki/Exhaust_gas

    e. Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, [1] or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle. It often disperses downwind in a pattern ...

  9. Bharat stage emission standards - Wikipedia

    en.wikipedia.org/wiki/Bharat_stage_emission...

    Bharat stage emission standards (BSES) are emission standards instituted by the Government of India to regulate the output of air pollutants from compression ignition engines and Spark-ignition engines equipment, including motor vehicles. The standards and the timeline for implementation are set by the Central Pollution Control Board under the ...
