  2. Two-stroke power valve system - Wikipedia

    en.wikipedia.org/wiki/Two-stroke_power_valve_system

    All power valve systems vary the duration of the exhaust port open time, which gives the engine usable low end power combined with excellent top end power. Manufacturers have also included sub exhaust chambers that extend the 'tuned length' of the expansion chamber. Power valve actuation can be by mechanical (RPM dependent) or electric (servo ...

  3. Valve actuator - Wikipedia

    en.wikipedia.org/wiki/Valve_actuator

    The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator. Another valve actuator is visible in the background, with windows to indicate the valve position. A valve actuator is the mechanism for opening and closing a valve. Manually ...

  4. Multi-valve - Wikipedia

    en.wikipedia.org/wiki/Multi-valve

    A cylinder head of a four valve Nissan VQ engine engine. A multi-valve or multivalve engine is one where each cylinder has more than two valves (an intake, and an exhaust).A multi-valve engine has better breathing, and with more smaller valves (having less mass in motion) may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.

  5. Power take-off - Wikipedia

    en.wikipedia.org/wiki/Power_take-off

    A PTO at the rear end of a farm tractor A PTO (in the box at the bottom) in the center of the three-point hitch of a tractor. A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.

  6. Four-stroke power valve system - Wikipedia

    en.wikipedia.org/wiki/Four-stroke_power_valve_system

    A four-stroke power valve is a device fitted to four-stroke engines that constantly adjusts the internal diameter of the exhaust system to better suit the speed of the engine. Yamaha was the first to develop such a system, called the Exhaust Ultimate Power Valve (EXUP). [1] It first appeared on the Yamaha FZR EXUP and was later used on many ...

  7. Valvetrain - Wikipedia

    en.wikipedia.org/wiki/Valvetrain

    Cutaway of a dual overhead camshaft engine 1969 AMC V8 overhead valve engine. The rocker cover has been removed, so elements of the pushrods, rocker arms, valve springs, and valves are visible. A valvetrain is a mechanical system that controls the operation of the intake and exhaust valves in an internal combustion engine. [1]

  8. Reciprocating engine - Wikipedia

    en.wikipedia.org/wiki/Reciprocating_engine

    Ray-traced image of a piston engine. There may be one or more pistons. Each piston is inside a cylinder, into which a gas is introduced, either already under pressure (e.g. steam engine), or heated inside the cylinder either by ignition of a fuel air mixture (internal combustion engine) or by contact with a hot heat exchanger in the cylinder (Stirling engine).

  9. Blowoff valve - Wikipedia

    en.wikipedia.org/wiki/Blowoff_valve

    A blowoff valve is designed to release pressure in the intake system when the throttle is closed. A "recirculating" type blowoff valve releases the pressurised air back into the non-pressurized section of the intake (i.e. upstream of the turbocharger), while an "atmospheric venting" type blowoff valve dumps the air directly into the atmosphere.
