  2. Timing belt (camshaft) - Wikipedia

    en.wikipedia.org/wiki/Timing_belt_(camshaft)

    In a piston engine, either a timing belt (also called a cambelt) or timing chain or set of timing gears is a perishable component used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons.

  3. Turbo timer - Wikipedia

    en.wikipedia.org/wiki/Turbo_timer

    A turbo timer in a Toyota Celica GT-Four. A turbo timer is a device designed to keep an automotive engine running for a pre-specified period in order to automatically execute the cool-down period required to prevent premature turbo wear and failure. Most turbo timers are based on digital electronics.

  4. Ignition timing - Wikipedia

    en.wikipedia.org/wiki/Ignition_timing

    Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.

  5. Timing mark - Wikipedia

    en.wikipedia.org/wiki/Timing_mark

    A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel. [1] These have the largest radius rotating at crankshaft speed and therefore are the place where marks at one degree intervals will be farthest apart.

  6. Big-bang firing order - Wikipedia

    en.wikipedia.org/wiki/Big-bang_firing_order

    This is achieved by changing the ignition timing, changing or re-timing the camshaft, and sometimes in combination with a change in crankpin angle. The goal is to change the power delivery characteristics of the engine. A regular-firing multi-cylinder engine fires at approximately even intervals, giving a smooth-running engine.

  7. Antilag system - Wikipedia

    en.wikipedia.org/wiki/Antilag_system

    The anti-lag system (ALS) is a method of reducing turbo lag or effective compression used on turbocharged engines to minimize turbo lag on racing or performance cars. It works by retarding the ignition timing and adding extra fuel (and sometimes air) to balance an inherent loss in combustion efficiency with increased pressure at the charging side of the turbo.

  8. Turbocharger - Wikipedia

    en.wikipedia.org/wiki/Turbocharger

    In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement .

  9. Aircraft engine starting - Wikipedia

    en.wikipedia.org/wiki/Aircraft_engine_starting

    Turning the engine" with the ignition and switches accidentally left "on" can also cause injury, as the engine can start unexpectedly when a spark plug fires. If the switch is not in start position, the spark will occur before the piston hits top dead center, which can force the propeller to violently kick back.
