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 ...
A straight-twin engine, also known as an inline-twin, vertical-twin, inline-2, or parallel-twin, is a two-cylinder piston engine whose cylinders are arranged in a line along a common crankshaft. Straight-twin engines are primarily used in motorcycles; other uses include automobiles, marine vessels, snowmobiles, jet skis , all-terrain vehicles ...
Robin (a subsidiary of Subaru Corporation) previously developed and supplied all-terrain vehicle (ATV) and snowmobile engines for Polaris Inc. Starting in 1995 with the Polaris Magnum 425 4-stroke ATV and in 1997, with the introduction of the "twin 700" snowmobile engine Polaris started the development and production in house of the "Liberty ...
Honda upgraded the two-stroke engine to 342 cc (20.9 cu in) which was later decreased to 329 cc (20.1 cu in) in a recall. [3] The engine was mounted behind the driver, [ 2 ] and featured 6.7:1 compression , capacitor discharge ignition a 32 mm (1.26 in)-throat Keihin carburetor , and added electric starting. [ 2 ]
An indicator diagram is a chart used to measure the thermal, or cylinder, performance of reciprocating steam and internal combustion engines and compressors. [1] An indicator chart records the pressure in the cylinder versus the volume swept by the piston, throughout the two or four strokes of the piston which constitute the engine, or ...
A carburetor (also spelled carburettor or carburetter) [1] [2] [3] is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. [4] The primary method of adding fuel to the intake air is through the Venturi effect or Bernoulli's principle in the main metering circuit, though various other ...
The original YZ250 of 1974 used an air-cooled 250cc two-stroke engine of 70 mm bore and a 64 mm stroke, which was improved semi-annually. The air-cooled motor was replaced in 1982 with a 249 cc liquid-cooled two-stroke reed-valved engine with a mechanical, rather than servo-driven, YPVS exhaust valve for a wider spread of power. Although other ...
Two-stroke motorcycles are a type of internal combustion engine that completes a power cycle with two strokes of the piston during only one crankshaft revolution.
