  2. Wide open throttle - Wikipedia

    en.wikipedia.org/wiki/Wide_open_throttle

    Wide open throttle or wide-open throttle (WOT), also called full throttle, is the fully opened state of a throttle on an engine (internal combustion engine or steam engine). The term also, by extension, usually refers to the maximum-speed state of running the engine, as the normal result of a fully opened throttle plate/ butterfly valve .

  3. Four-stroking - Wikipedia

    en.wikipedia.org/wiki/Four-stroking

    Four-stroking is a condition of two-stroke engines where combustion occurs every four strokes or more, rather than every two. Though normal in some instances at idle, extremely high engine speeds, and when letting off the throttle, such firing is uneven, noisy and may, in cases of malfunction, damage the engine if allowed to continue unabated.

  4. Two-stroke engine - Wikipedia

    en.wikipedia.org/wiki/Two-stroke_engine

    Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringent emissions regulation, two-stroke engines have been phased out in ...

  5. Two- and four-stroke engines - Wikipedia

    en.wikipedia.org/wiki/Two-_and_four-stroke_engines

    The four-stroke engine is more efficient when running at full throttle, while the opposite is the case for the two-stroke engine. When a small car under heavy load runs at half speed, the engine automatically switches to the two-cycle mode, which is then more efficient. The research on this showed a 27% reduction in fuel consumption. [8] [9]

  6. Engine efficiency - Wikipedia

    en.wikipedia.org/wiki/Engine_efficiency

    The engine efficiency is less than when the engine is operating at full throttle. One solution to this issue is to shift the load in a multi-cylinder engine from some of the cylinders (by deactivating them) to the remaining cylinders so that they may operate under higher individual loads and with correspondingly higher effective compression ratios.

  7. Two-stroke power valve system - Wikipedia

    en.wikipedia.org/wiki/Two-stroke_power_valve_system

    The only moving parts inside simple two-stroke engines are the crankshaft, the connecting rod, and the piston. It is the same simplicity in design, however, that causes a two-stroke engine to be less fuel-efficient and produce high specific levels of undesirable exhaust gas emissions. At the bottom of the power stroke, the transfer ports, which ...

  9. General Motors 122 engine - Wikipedia

    en.wikipedia.org/wiki/General_Motors_122_engine

    A stroked version of the 1.8-liter engine, displacing 2.0 liters, was introduced midway through 1982, to provide more low-end power for the J-cars. This engine replaced the 1.8-liter engine altogether and had throttle-body fuel injection. It produced 86 hp (64 kW), and 110 lb⋅ft (150 N⋅m). Applications: 1983–1986 Buick Skyhawk
