Amable Liñán introduced a modified mixture fraction in 1991 [6] [7] that is appropriate for systems where the fuel and oxidizer have different Lewis numbers. If L e F {\displaystyle Le_{F}} and L e O 2 {\displaystyle Le_{O_{2}}} are the Lewis number of the fuel and oxidizer, respectively, then Liñán's mixture fraction is defined as
Chainsaw engines are traditionally either a two-stroke single-cylinder gasoline (petrol) internal combustion engine (usually with a cylinder volume of 30 to 120 cm 3) or an electric motor driven by a battery or electric power cord. In a petrol chainsaw, fuel is generally supplied to the engine by a carburetor at the intake.
McCulloch Motors Corporation is an American manufacturer of chainsaws and other outdoor power tools. The company was founded in Milwaukee, Wisconsin, in 1943 by Robert Paxton McCulloch as a manufacturer of small two-stroke gasoline engines and introduced its first chainsaw in 1948, the Model 5-49. McCulloch and its brand are owned by Husqvarna.
The advantage of using equivalence ratio over fuel–oxidizer ratio is that it takes into account (and is therefore independent of) both mass and molar values for the fuel and the oxidizer. Consider, for example, a mixture of one mole of ethane (C 2 H 6) and one mole of oxygen (O 2). The fuel–oxidizer ratio of this mixture based on the mass ...
For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.

The heart of the Mitsubishi's MVV system is the linear air–fuel ratio exhaust gas oxygen sensor. Compared with standard oxygen sensors, which essentially are on-off switches set to a single air/fuel ratio, the lean oxygen sensor is more of a measurement device covering the air/fuel ratio range from about 15:1 to 26:1.

Husqvarna Motorcycles GmbH (Swedish: [ˈhʉ̂ːsˌkvɑːɲa] ⓘ; marketed as Husqvarna) is an Austrian motorcycle company with Swedish origins. The company began producing motorcycles in 1903 at Huskvarna , Sweden, as a subsidiary of the Husqvarna armament firm. [ 1 ]
