  2. Compression release - Wikipedia

    en.wikipedia.org/wiki/Compression_release

    The most common kind of small engine compression release uses a camshaft mounted mechanical lever that pushes the exhaust valve tappet slightly, venting engine compression through the exhaust valve. Once the engine spins to starting speed, centrifugal force causes the lever to move out of the way, and the exhaust valve is allowed to seat fully.

  3. Compression release engine brake - Wikipedia

    en.wikipedia.org/wiki/Compression_release_engine...

    A compression release engine brake, compression brake, or decompression brake is an engine braking mechanism installed on some diesel engines. When activated, it opens exhaust valves to the cylinders, right before the compression stroke ends, releasing the compressed gas trapped in the cylinders, and slowing the vehicle.

  4. Engine braking - Wikipedia

    en.wikipedia.org/wiki/Engine_braking

    A compression release brake (also known as a Jacobs brake or "jake brake"), is the type of brake most commonly confused with real engine braking; it is used mainly in large diesel trucks and works by opening the exhaust valves at the top of the compression stroke, so the large amount of energy stored in that compressed air is not returned to ...

    In 2016, the Milwaukee-Eight engines became available on Touring and Trike models of the 2017 model year. The Softail models started using the Milwaukee-Eight the following year. The most significant change from the Twin Cam are the two extra valves per cylinder head which produce 10 percent more torque.

  6. Desmodromic valve - Wikipedia

    en.wikipedia.org/wiki/Desmodromic_valve

    A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases at the end of the cycle. In a conventional ...

    This had a compression release added to the front left exhaust tappet cover resulting in a square versus triangular cover found on the other exhaust and intake covers. Upon removal of the compression release mechanism in 1974 due to updated starter, the square cover at the left exhaust valve was continued. Brake modification notes:

    en.wikipedia.org/wiki/BSA_B40

    The BSA B40 was a series of 350 cc (21 cu in) unit construction single-cylinder OHV four-stroke motorcycles made by the Birmingham Small Arms Company.Developed from the BSA C15, the machines were produced between 1961 and 1967 for civilian use.

  9. Suzuki Hayabusa - Wikipedia

    The compression ratio was boosted from 11:1 to 12.5:1 and the cylinder head was made more compact and was given lighter titanium valves, saving 14.1 g (0.50 oz) and 11.7 g (0.41 oz) on each intake and exhaust valve, respectively. The valves were driven by a chain with a new hydraulic tensioner.
