  2. Hypereutectic piston - Wikipedia

    en.wikipedia.org/wiki/Hypereutectic_piston

    However, hypereutectic pistons experience less thermal expansion than forged pistons. For this reason, hypereutectic pistons can run a tighter piston to cylinder clearance than forged pistons. This makes hypereutectic pistons a better choice for stock engines, where longevity is more important than ultimate performance.

  3. Gudgeon pin - Wikipedia

    en.wikipedia.org/wiki/Gudgeon_pin

    The gudgeon pin is typically a forged short hollow rod made of a steel alloy of high strength and hardness that may be physically separated from both the connecting rod and piston or crosshead. [1] The design of the gudgeon pin, especially in the case of small, high-revving automotive engines is challenging.

  4. Ford 335 engine - Wikipedia

    en.wikipedia.org/wiki/Ford_335_engine

    The forged pistons were changed to flat-top style and the heads to open chamber heads, but retained the same large ports, valves, and adjustable valve train used in 1971. [5] This resulted in a compression ratio decreased to 9.2:1 while the cleaner-burning open-chamber heads helped meet the new emissions regulations. [1]

  5. Ford straight-six engine - Wikipedia

    en.wikipedia.org/wiki/Ford_straight-six_engine

    Only the block, crankshaft, pistons and conrods were carried over from the old engine. [19] Whereas the previous integral "log head" engine borrowed from the Ford FE engine family design, the new crossflow engine borrowed from the Cleveland V8 family, which was manufactured alongside the straight six at Ford Australia's Geelong Engine Plant.

  6. Hyundai Theta engine - Wikipedia

    en.wikipedia.org/wiki/Hyundai_Theta_engine

    The turbo used is a Mitsubishi TD04 model, the block used is very similar to the 4B11T engine found in Mitsubishi Lancer Evolution X, however most of the rotating assembly is different, with different rod lengths, bearing sizes, and piston compression heights. Additionally the 4B11T is a semi-closed deck block, where the Theta is an open deck ...

  7. Chevrolet small-block engine (first- and second-generation)

    en.wikipedia.org/wiki/Chevrolet_small-block...

    The pistons used in the 4.3 L V8 were the same as the Vortec 5000's, but longer 5.94 in (150.9 mm) connecting rods were used to compensate for the shorter stroke. The L99 featured updated Generation II block architecture, and is externally identical to the larger 5.7 L LT1 Generation II V8.

  8. List of Subaru engines - Wikipedia

    en.wikipedia.org/wiki/List_of_Subaru_engines

    For the first time in a Subaru engine, the centerlines of the cylinder bores do not intersect with the crankshaft axis to reduce friction during the piston downstroke; instead, there is a crank offset of 8 mm (0.31 in). Overall thermal efficiency is 40% due to the adoption of lean-burn combustion with an excess air ratio (λ) of 2. [32]

  9. 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.
