  2. Oil pump (internal combustion engine) - Wikipedia

    en.wikipedia.org/wiki/Oil_pump_(internal...

    The oil pump is an internal combustion engine part that circulates engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. This lubricates the bearings, allows the use of higher-capacity fluid bearings , and also assists in cooling the engine.

  3. Distributor - Wikipedia

    en.wikipedia.org/wiki/Distributor

    In older distributors, adjusting the ignition timing is usually achieved through both mechanical advance and vacuum advance. Mechanical advance adjusts the timing based on the engine speed (rpm), using a set of hinged weights attached to the distributor shaft. These weights cause the breaker points mounting plate to slightly rotate, thereby ...

  4. Head gasket - Wikipedia

    en.wikipedia.org/wiki/Head_gasket

    In an internal combustion engine, a head gasket provides the seal between the engine block and cylinder head(s). Its purpose is to seal the combustion gases within the cylinders and to avoid coolant or engine oil leaking into the cylinders. [1] Leaks in the head gasket can cause poor engine running and/or overheating.

  5. Crankcase ventilation system - Wikipedia

    en.wikipedia.org/wiki/Crankcase_ventilation_system

    Gaskets and shaft seals were intended to limit the leakage of oil, but they were usually not expected to entirely prevent it. The blow-by gases would diffuse through the oil and then leak through the seals and gaskets into the atmosphere, causing air pollution and odors. The first refinement in crankcase ventilation was the road draught tube.

  6. Seal (mechanical) - Wikipedia

    en.wikipedia.org/wiki/Seal_(mechanical)

    A type of washer with integral gasket, widely used to provide a seal at the entry point of a screw or bolt [2] [3] Bridgman seal, a piston sealing mechanism that creates a high pressure reservoir from a lower pressure source; Split seals [4] are innovative sealing solutions designed to enhance efficiency and convenience in various mechanical ...

  7. Gasket - Wikipedia

    en.wikipedia.org/wiki/Gasket

    Sheet gaskets are simple, they are cut to size either with bolt holes or without holes for standard sizes with various thickness and material suitable to media and temperature pressure of pipeline. Ring gaskets also known as RTJ. They are mostly used in offshore oil- and gas pipelines and are designed to work under extremely high pressure. They ...

  8. Automobile engine replacement - Wikipedia

    en.wikipedia.org/wiki/Automobile_engine_replacement

    A long block does not include the fuel system, electrical, intake, and exhaust components, as well as other components. A long block may include the balancer/damper, timing cover, oil pan and valve covers. [5] A long block engine replacement typically requires swapping out parts from the original engine to the long block.

  9. Dry sump - Wikipedia

    en.wikipedia.org/wiki/Dry_sump

    The dry-sump system uses two or more oil pumps and a separate oil reservoir, as opposed to a conventional wet-sump system, which uses only the main sump (U.S.: oil pan) below the engine and a single pump. A dry-sump engine requires a pressure relief valve to regulate negative pressure inside the engine, so internal seals are not inverted.
