  2. Two-stroke power valve system - Wikipedia

    en.wikipedia.org/wiki/Two-stroke_power_valve_system

    A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...

    In 1979, Japan received a shipment of Low rider magazines, which showed on the cover a lowered Chevy in front of Mount Fuji. This magazine, Orlie's Lowriding Magazine, was a profitable magazine that advertised lowriders and hydraulic kits for their consumers. [4] Along with these magazines came mail-order forms to purchase automotive hydraulics ...

  4. Two-stroke engine - Wikipedia

    en.wikipedia.org/wiki/Two-stroke_engine

    Animation of a two-stroke engine. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle.

  5. Two- and four-stroke engines - Wikipedia

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

    The M4+2 engine, also known as the double-piston internal combustion engine, is a type of internal combustion engine invented by Polish patent holder Piotr Mężyk. [1] The M4+2 engine took its name from a combination of two-stroke engines and four-stroke engines. The two-stroke combustion engine is characterized by a simple construction and ...

  6. Single- and double-acting cylinders - Wikipedia

    en.wikipedia.org/wiki/Single-_and_double-acting...

    Typical horizontal steam engine with double-acting cylinder. A double-acting cylinder is a cylinder in which the working fluid acts alternately on both sides of the piston. . In order to connect the piston in a double-acting cylinder to an external mechanism, such as a crank shaft, a hole must be provided in one end of the cylinder for the piston rod, and this is fitted with a gland or ...

  7. Hydraulic intensifier - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_intensifier

    There are two specialized types of hydraulic intensifier used for water jet cutting. The first and most common is the inline hydraulic intensifier. Oscillating hydraulic pistons are used to compress water to the required pressure levels. The water jet system's cutting head restricts the water flow to generate pressure and direct it onto the ...

  8. Valve timing - Wikipedia

    en.wikipedia.org/wiki/Valve_timing

    In four-stroke cycle engines and some two-stroke cycle engines, the valve timing is controlled by the camshaft. It can be varied by modifying the camshaft, or it can be varied during engine operation by variable valve timing. It is also affected by the adjustment of the valve mechanism, and particularly by the tappet clearance.
