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.

To calculate the actual efficiency of an engine requires the energy density of the fuel being used. Different fuels have different energy densities defined by the fuel's heating value. The lower heating value (LHV) is used for internal-combustion-engine-efficiency calculations because the heat at temperatures below 150 °C (300 °F) cannot be ...
The M4+2 engine has a four-stroke piston and a two-stroke piston. The shaft of the four-stroke piston rotates twice as fast as the shaft of the two-stroke piston, and the two-stroke part always runs at half speed. This ensures that both parts work optimally regarding fuel consumption at all times.
The car drew criticism. Experts remarked on its primitive look and the "uncultivated" noise from the two-stroke engine. The "two-stroke" fuel mixture of gasoline/petrol with oil was expensive, and the Type P used a lot of it. It had a prodigious appetite for spark plugs. A relatively short operating life was anticipated also on account of the ...
In internal combustion engines, a split-single design is a type of two-stroke where two cylinders share a single combustion chamber. The first production split-single engine was built in 1918 and the design was used on several motorcycles and cars until the mid-1950s, although Puch continued producing split-single engines for motorcycles until ...
The engine has a displacement of 2.0 L; 121.9 cu in (1,998 cc) with a bore and a stroke of 3.38 in × 3.38 in (86 mm × 86 mm). [2] The compression ratio of the engine is 10.5:1. [2] The 2.0 L engine was offered by Dodge in the Dodge Caliber. Outside North America, the 2.0 was the base engine for the 2007 Chrysler Sebring and 2008 Dodge Avenger.
The Handmaid's Tale took advantage of telling the story in a more modern era by leaning into the developments that have been made and having the show take place in the present instead of back in ...
