  2. 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 ...

  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. Tuned exhaust - Wikipedia

    en.wikipedia.org/wiki/Tuned_exhaust

    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. Extractors/headers usually have equal length pipes for each cylinder, whereas a more basic exhaust manifold may have unequal length pipes.

  5. Manifold (fluid mechanics) - Wikipedia

    en.wikipedia.org/wiki/Manifold_(fluid_mechanics)

    Exhaust manifold An engine part that collects the exhaust gases from multiple cylinders into one pipe. Also known as headers. Hydraulic manifold A component used to regulate fluid flow in a hydraulic system, thus controlling the transfer of power between actuators and pumps Inlet manifold (or "intake manifold")

  6. Reverse-flow cylinder head - Wikipedia

    en.wikipedia.org/wiki/Reverse-flow_cylinder_head

    The inlet manifold of a reverse-flow cylinder head may be connected to the exhaust by a heat riser to transfer further heat, improving low rpm response and emissions as a result. Costs can be reduced in production engines by casting the inlet and exhaust manifolds as one unit. This also transfers further heat to the inlet eliminating the need ...

  7. Expansion chamber - Wikipedia

    en.wikipedia.org/wiki/Expansion_chamber

    The vacuum wave arrives in the cylinder during the transfer cycle and helps suck in fresh mixture from the crankcase into the cylinder, and/or prevent the suction of exhaust gases into the crankcase (due to crankcase vacuum). [3] However, the wave may also suck fresh mixture out the exhaust port into the header of the expansion chamber.

    Also gas pedal. A throttle in the form of a foot-operated pedal, or sometimes a hand-operated lever or paddle, by which the flow of fuel to the engine (and thereby the engine speed) is controlled, with depression of the pedal causing the vehicle to accelerate. admission stroke See induction stroke. aftermarket air brake 1. A type of brake in which the force that actuates the brake mechanism is ...

    Header The structural roof beam above the windshield. [3] Alternatively, header can refer to the section of exhaust piping attached to the cylinder head. The Hofmeister kink at the base of the C-pillar of this BMW 3.0 CS is adorned with a BMW roundel Hofmeister kink BMW's trademark reverse-sweep kick at the bottom of last roof pillar.
