  2. Stud welding - Wikipedia

    en.wikipedia.org/wiki/Stud_welding

    Stud welding uses a flux tip and a ferrule, a ceramic ring which concentrates the heat, prevents oxidation and retains the molten metal in the weld zone. The ferrule is broken off of the fastener after the weld is completed. This lack of marring on the side opposite the fastener is what differentiates stud welding from other fastening processes ...

  3. Exhaust manifold - Wikipedia

    en.wikipedia.org/wiki/Exhaust_manifold

    When the exhaust valve opens, the high pressure exhaust gas escapes into the exhaust manifold or header, creating an "exhaust pulse" comprising three main parts: The high-pressure head is created by the large pressure difference between the exhaust in the combustion chamber and the atmospheric pressure outside of the exhaust system

  4. Ethernet frame - Wikipedia

    en.wikipedia.org/wiki/Ethernet_frame

    The SNAP header allows EtherType values to be used with all IEEE 802 protocols, as well as supporting private protocol ID spaces. In IEEE 802.3x-1997, the IEEE Ethernet standard was changed to explicitly allow the use of the 16-bit field after the MAC addresses to be used as a length field or a type field.

    The Ford GT40 is a high-performance mid-engined racing car originally designed and built for and by the Ford Motor Company to compete in 1960s European endurance racing.Its specific impetus was to best Scuderia Ferrari, which had won the prestigious 24 Hours of Le Mans race for six years running from 1960 to 1965.

  6. Exhaust brake - Wikipedia

    en.wikipedia.org/wiki/Exhaust_brake

    An exhaust brake is a means of slowing a diesel engine by closing off the exhaust path from the engine, causing the exhaust gases to be compressed in the exhaust manifold, and in the cylinder. Since the exhaust is being compressed, and there is no fuel being applied, the engine slows down the vehicle: the crankshaft (and, hence, the wheels ...

  7. Exhaust system - Wikipedia

    en.wikipedia.org/wiki/Exhaust_system

    Exhaust system of the Opel Corsa B 1.2 petrol Exhaust manifold (chrome plated) on a car engine. 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 ...

  8. Oldsmobile V8 engine - Wikipedia

    en.wikipedia.org/wiki/Oldsmobile_V8_engine

    The Oldsmobile engine was very similar to the Buick engine, but not identical: it had larger wedge combustion chambers with flat-topped (rather than domed) pistons, six bolts rather than five per cylinder head, and slightly larger intake valves; the valves were actuated by shaft-mounted rocker arms like the Buick and Pontiac versions, but the ...

  9. 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 .
