  2. Engine displacement - Wikipedia

    en.wikipedia.org/wiki/Engine_displacement

    Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1] It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed ) an engine might be capable of producing ...

  3. Diesel fuel tanks in trucks - Wikipedia

    en.wikipedia.org/wiki/Diesel_fuel_tanks_in_trucks

    Replacing a cylindrical fuel tank with a D-Tank can result in 46% additional fuel capacity. When calculating volume requirements, one would begin by assessing the available space. Once length, width and height restrictions have been ascertained, the easiest method of determining volume is with the use of a truck tank volume calculator.

  4. Displacement (fluid) - Wikipedia

    en.wikipedia.org/wiki/Displacement_(fluid)

    Measurement of volume by displacement, (a) before and (b) after an object has been submerged. The amount by which the liquid rises in the cylinder (∆V) is equal to the volume of the object. In fluid mechanics, displacement occurs when an object is largely immersed in a fluid, pushing it out of the way and taking its place. The volume of the ...

  5. Volumetric flow rate - Wikipedia

    en.wikipedia.org/wiki/Volumetric_flow_rate

    The area required to calculate the volumetric flow rate is real or imaginary, flat or curved, either as a cross-sectional area or a surface. The vector area is a combination of the magnitude of the area through which the volume passes through, A , and a unit vector normal to the area, n ^ {\displaystyle {\hat {\mathbf {n} }}} .

  6. Compression ratio - Wikipedia

    en.wikipedia.org/wiki/Compression_ratio

    Absolute cylinder pressure is used to calculate the dynamic compression ratio, using the following formula: = where is a polytropic value for the ratio of specific heats for the combustion gases at the temperatures present (this compensates for the temperature rise caused by compression, as well as heat lost to the cylinder)

  7. Stroke ratio - Wikipedia

    en.wikipedia.org/wiki/Stroke_ratio

    The Jaguar XK6 engine, used in all 6-cylinder Jaguars from 1949 to 1987 was undersquare. For example, the 4.2 litre engine had a bore and stroke of 92.08 mm × 106 mm (3.63 in × 4.17 in), providing a bore/stroke ratio of 0.869:1. Virtually all piston engines used in military aircraft were long-stroke engines.

  8. Piston motion equations - Wikipedia

    en.wikipedia.org/wiki/Piston_motion_equations

    The graphs below show the angle domain equations for a constant rod length (6.0") and various values of half stroke (1.8", 2.0", 2.2"). Note in the graphs that L is rod length l {\displaystyle l} and R is half stroke. r {\displaystyle r} .

  9. Volumetric efficiency - Wikipedia

    en.wikipedia.org/wiki/Volumetric_efficiency

    It also denotes the ratio of equivalent air volume drawn into the cylinder to the cylinder's swept volume. [5] This equivalent volume is commonly inserted into a mass estimation equation based upon Boyle's Gas Law. When VE is multiplied by the cylinder volume, an accurate estimate of cylinder air mass (charge) can be made for use in determining ...
