2. Catalytic converter - Wikipedia

   en.wikipedia.org/wiki/Catalytic_converter

   Catalytic converter. A catalytic converter is an exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including ...

3. Exhaust system - Wikipedia

   en.wikipedia.org/wiki/Exhaust_system

   An exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, the exhaust gas may flow through one or more of the following: A turbocharger to increase ...

4. 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.

5. 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 ...

6. Turbocharger - Wikipedia

   en.wikipedia.org/wiki/Turbocharger

   Cut-away view turbocharger (turbine section on the left, compressor section on the right) In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in ...

7. Internal combustion engine - Wikipedia

   en.wikipedia.org/wiki/Internal_combustion_engine

   An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high- temperature and high- pressure gases produced by combustion ...
