The history of the motor Cayley began in 1807 thanks to Sir George Cayley. In its original version what is a bain marie is an example of the internal combustion engine. In this and the next post will not be discussed in this release, but the variations in external combustion type free piston much more interesting and might even be unpublished. The motors shown are the result of countless what is a bain marie arguments with facts to the person who has made me closer to the world of external combustion engines. Will be presented what is a bain marie versions what is a bain marie of increasing complexity theoretical (but not constructive) to be able to discuss the principles of operation more easily. Actually I do not have the assurance that the classification engine as Cayley is correct because in fact there is a certain similarity with the engine Ericsson. If someone bring himself to break the dilemma can do this by writing in the comments to this post. A common characteristic engine Cayley is the presence of two pistons of different diameter that move synchronously, and for this reason normally joined together what is a bain marie so as to constitute a single body. The figure shows the animation of the first variant.
The engine consists of two pistons of different diameters integral. The piston with the smaller what is a bain marie diameter of moves in a cylinder whose walls are kept cold (indicated in blue color). Later on we will refer to this piston piston cold calling. The piston with the larger diameter working in a cylinder whose walls are kept hot (indicated in red). Later on we will refer to this calling piston piston hot. To effect the movement of the different diameters of the piston upwards causes an increase of the volume, the downward movement determines a reduction. For a given displacement what is a bain marie of the piston the volume change of volume of hot and cold can be expressed as DeltaV hot hot * = S x = S DeltaV cold cold * (-x) in which hot DeltaV is the volume change of hot expressed in m 3 S is the hot surface of the hot piston expressed in m 2 DeltaV cold is the volume change of cold expressed in m 3 S is the cold surface of the cold piston expressed what is a bain marie in m 2 x is the displacement in m For the sake of simplicity it is assumed that the gas is at two different temperatures. The gas in the upper chamber to the hot temperature, the gas in the lower chamber to the cold temperature. The pressure is the same at every point between the two pistons as the two chambers are in communication between them and is given by the following relation: P = n * R / [(V hot / warm T) + (V cold / cold T )] where P is the pressure expressed in Pa n is the amount of gas contained in the engine during the transformation expressed in moles R is the gas constant and is worth 8.314 J mol -1 K -1 V is the volume of hot gas content in the hot cylinder in m 3 V is the volume of cold gas in the cylinder cold in m 3 T hot is the temperature of the hot cylinder expressed in KT cold is the temperature of the cold cylinder K expressed in order for the engine to operate is required that during the expansion, that is, when the piston rises, the pressure increases. Conversely, during the compression, that is, when the piston descends, the pressure must decrease. To ensure this behavior is sufficient to comply with the condition that follows S hot / cold S <T hot / cold T In practice the movement of the piston from the bottom upwards what is a bain marie must generate an expansion with pressurization (increases both the volume and pressure), while the reverse movement must produce a compression depressurization (decreases both the volume and pressure). The two processes are not superimposed in the plane PV because they occur with different amounts of gas. In the motor is contained a larger amount of gas when making the upward movement, the lower when it moves downwards. The following was reported in the cycle PV diagram relating to an engine in which the ratio between the hot surface and the cold surface is equal to 1.5 and the operating temperatures are cold T = 300K and T = 600K hot. Immediately below was plotted the amount of gas as a function of the volume what is a bain marie of the engine in the various phases what is a bain marie of the cycle.
The cycle consists of four phases. Step AB: expansion with pressurization what is a bain marie Step BC: depressurization isochoric through the exhaust gas to the outside Step CD: compression with depressurization Step FROM: isochoric pressurization what is a bain marie gas by suction from the outside Regarding you
