What the role of air displacement in engine?
It's just the complement to fuel displacement. How much air the engine takes in affects how much fuel it can burn.
Displacement and cubic inches are one in the same. Engine displacement is calculated using the bore, stroke, and number of cylinders: Displacement = [(Pi) (r^2)] [stroke] [number of cylinders] Alternatively, displacement must sometimes be defined as the total volume of air/fuel mixture an engine draws in during one complete engine cycle, howsoever defined and subject to further interpretation by taxation and racing authorities.
formula for displacement: A=(pi)r^2 A is Area Pi is 3.14 and R is the radius of the cylinder, this is the piston in Square inches. then multiply that by the distance the piston travels, that is the displacement of one cylinder to find total engine displacement multiply that by how many pistons are in the engine to get total engine displacement
I hope you are asking about non-positive displacement air compressors. The air compressors are broadly classified into 1. displacement (positive) compressors. 2. steady flow or non-positive displacement compressors. DISPLACEMENT COMPRESSORS: In this type of air compressors air is compressed by being trapped between two engaging surfaces. NON-POSITIVE DISPLACEMENT COMPRESSORS: Compression occurs by transfer of kinetic energy from a rotor.
Liters is a description of the engine size or displacement. Wikipedia has this description Engine displacement is defined as the total volume of air/fuel mixture an engine can draw in during one complete engine cycle; it is normally stated in cubic centimetres, litres or cubic inches. In a piston engine, this is the volume that is swept as the pistons are moved from top dead centre to bottom dead centre.
cc means cubic centimeters. It refers to the displacement of the cylinder that is caused by the combustion of the fuel. For a multi cylinder engine, the displacement of all of the cylinders are added together for total engine displacement. In automobiles, you sometimes see engine displacement expressed in liters. (1 liter equals 1000 cc)
1.6 refers to engine displacement as in 1.6 liters Engine displacement is the volume swept by all the pistons of an engine in a single movement from top dead center to bottom dead center. It is commonly specified in cubic centimeters, liters, or cubic inches. Power output of a combustion engine is directly proportional to the engine displacement. (source wikipedia)
Cubic inches of displacement in reference to a car is the volume of the cylinders in the engine in cubic inches. In most American muscle cars, part of the name refers to the displacement of the engine in cubic inches, for example the Chevrolet Chevelle SS454 has a 454 ci engine and the Oldsmobile 440 had a 440 ci engine.
One method of measuring engine size, and the most common, refers to the 'displacement' of the engine. This is calculated by measuring the difference in the volume of an engine cylinder when the piston is at the bottom of its travel and when it is at the top of its travel. This is the displacement of an individual cylinder. Multiplying this amount by the number of cylinders gives the engine displacement. Therefore, the total displacement…
