2. Secondary air injection - Wikipedia

   en.wikipedia.org/wiki/Secondary_air_injection

   A sensitive reed valve assembly called the aspirator valve is placed in the air injection pumping, which draws its air directly from the clean side of the air filter. During engine idle, brief but periodic negative pressure pulses in the exhaust system draw air through the aspirator valve and into the exhaust stream at the catalytic converter.

3. Wastegate - Wikipedia

   en.wikipedia.org/wiki/Wastegate

   Wastegate. A wastegate is a valve that controls the flow of exhaust gases to the turbine wheel in a turbocharged engine system. [1] Diversion of exhaust gases regulates the turbine speed, which in turn regulates the rotating speed of the compressor. The primary function of the wastegate is to regulate the maximum boost pressure in turbocharger ...

4. Blowoff valve - Wikipedia

   en.wikipedia.org/wiki/Blowoff_valve

   A blowoff valve is designed to release pressure in the intake system when the throttle is closed. A "recirculating" type blowoff valve releases the pressurised air back into the non-pressurized section of the intake (i.e. upstream of the turbocharger), while an "atmospheric venting" type blowoff valve dumps the air directly into the atmosphere.

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. Scavenging (engine) - Wikipedia

   en.wikipedia.org/wiki/Scavenging_(engine)

   Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air/fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle. If scavenging is incomplete, the remaining exhaust gases can cause improper combustion for the next cycle, leading to reduced power ...

7. Oil filter - Wikipedia

   en.wikipedia.org/wiki/Oil_filter

   Oil filter. An oil filter is a filter designed to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. Their chief use is in internal-combustion engines for motor vehicles (both on- and off-road ), powered aircraft, railway locomotives, ships and boats, and static engines such as generators and pumps.
