  2. Straight engine - Wikipedia

    en.wikipedia.org/wiki/Straight_engine

    A straight engine is easier to build than an equivalent flat engine or V engine, as it uses one cylinder head rather than two. Inline engines are also narrower than flat engines or V engines; however, they are longer and can be taller. The engine balance characteristics of a straight engine depend on the number of cylinders and the firing interval.

  3. Engine displacement - Wikipedia

    en.wikipedia.org/wiki/Engine_displacement

    Wankel engines are able to produce higher power levels for a given displacement. Therefore, they are generally taxed as 1.5 times [citation needed] their stated physical displacement (1.3 litres becomes effectively 2.0, 2.0 becomes effectively 3.0), although actual power outputs can be higher than suggested by this conversion factor. The ...

  4. Straight-six engine - Wikipedia

    en.wikipedia.org/wiki/Straight-six_engine

    Straight-six engines are typically produced in displacements ranging from 2 to 4 L (122 to 244 cu in), [4]: p209 however engines ranging in size from the 0.7 L (43 cu in) Benelli 750 Sei motorcycle engine [5] to the 10,972.2 L (669,565 cu in) Wärtsilä-Sulzer RTA96-C two-stroke marine diesel engine. Due to its well-balanced configuration, the ...

  5. Straight-four engine - Wikipedia

    en.wikipedia.org/wiki/Straight-four_engine

    The majority of automotive four-cylinder engines use a straight-four layout [1]: pp. 13–16 (with the exceptions of the flat-four engines produced by Subaru and Porsche) [2] and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines.

  6. Least count - Wikipedia

    en.wikipedia.org/wiki/Least_Count

    The dieter's problem: this scale can only resolve weight changes of 0.2 lbs, even though the digital display looks as if it could show 0.1 In the science of measurement , the least count of a measuring instrument is the smallest value in the measured quantity that can be resolved on the instrument's scale.

  7. Sphere packing in a cylinder - Wikipedia

    en.wikipedia.org/wiki/Sphere_packing_in_a_cylinder

    Sphere packing in a cylinder is a three-dimensional packing problem with the objective of packing a given number of identical spheres inside a cylinder of specified diameter and length. For cylinders with diameters on the same order of magnitude as the spheres, such packings result in what are called columnar structures .

  8. Firing order - Wikipedia

    en.wikipedia.org/wiki/Firing_order

    For this inline-4 engine, 1-3-4-2 could be a valid firing order.. The firing order of an internal combustion engine is the sequence of ignition for the cylinders.. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated.

  9. Cylinder-head-sector - Wikipedia

    en.wikipedia.org/wiki/Cylinder-head-sector

    CHS addressing starts at 0/0/1 with a maximal value 1023/255/63 for 24=10+8+6 bits, or 1023/254/63 for 24 bits limited to 255 heads. CHS values used to specify the geometry of a disk have to count cylinder 0 and head 0 resulting in a maximum (1024/256/63 or) 1024/255/63 for 24 bits with (256 or) 255 heads.
