  2. Piston - Wikipedia

    en.wikipedia.org/wiki/Piston

    A slipper piston is a piston for a petrol engine that has been reduced in size and weight as much as possible. In the extreme case, they are reduced to the piston crown, support for the piston rings, and just enough of the piston skirt remaining to leave two lands so as to stop the piston rocking in the bore.

    en.wikipedia.org/wiki/Reciprocating_engine

    In some designs the piston may be powered in both directions in the cylinder, in which case it is said to be double-acting. Steam piston engine A labeled schematic diagram of a typical single-cylinder, simple expansion, double-acting high pressure steam engine. Power takeoff from the engine is by way of a belt.

  4. Piston motion equations - Wikipedia

    en.wikipedia.org/wiki/Piston_motion_equations

    The angle domain equations above show that the motion of the piston (connected to rod and crank) is not simple harmonic motion, but is modified by the motion of the rod as it swings with the rotation of the crank. This is in contrast to the Scotch Yoke which directly produces simple harmonic motion.

  5. Component parts of internal combustion engines - Wikipedia

    en.wikipedia.org/wiki/Component_parts_of...

    A piston is a component of reciprocating engines. It is located in a cylinder and is made gas-tight by piston rings. Its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In two-stroke engines the piston also acts as a valve by covering and uncovering ports in the cylinder ...

  6. Four-stroke engine - Wikipedia

    en.wikipedia.org/wiki/Four-stroke_engine

    The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy. A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of ...

    Diagram showing the operation of a 4-stroke SI engine. Labels: 1 ‐ Induction 2 ‐ Compression 3 ‐ Power 4 ‐ Exhaust. The top dead center (TDC) of a piston is the position where it is nearest to the valves; bottom dead center (BDC) is the opposite position where it is furthest from them.

  8. Axial piston pump - Wikipedia

    en.wikipedia.org/wiki/Axial_piston_pump

    Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.

  9. Piston pump - Wikipedia

    en.wikipedia.org/wiki/Piston_pump

    Piston pump compared to a plunger pump. A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston. [1] Piston pumps can be used to move liquids or compress gases. They can operate over a wide range of pressures. High pressure operation can be achieved without adversely affecting flow rate.
