Cylinder
CylinderWith, heat engine reciprocating engine piston. There is a similar part to also the injector and the wind instrument. Below reciprocating engine.
Summary
The cylinder in the early engine was the largest part in the engine. Concerning the friction which the piston brings how you lighten various experiments were done. In the steam engine the moisture which occurs in order to operate as an antifriction material, there is no lubricating mechanism, or was and they were simple ones.
external combustion engine because there is no combustion chamber has symmetrical structure.Working fluidHeat energyExpansionIt converts to kinetic energy with and transmits to the piston. Inside the cylinder in smooth case is many, can install the gasket in the piston and is separated closing airtight two rooms. As for motion of the piston you take come out in the form of reciprocating motion in the straight line and, you have converted to rotational energy with the crank outside. As for the cylinder it can change inhalation exhaust with the sliding valve which belongs, it is possible to remove 2 time kinetic energies with one round trip. Mainly steam engine. Stirling engine the cylinder there are also some which operate as a heat exchanger
internal combustion engine external combustion engine, as for basic structure and function external combustion engine, but it became complicated. As for one end piston・Cylinder headWithCombustion chamberTo form, that with the capacity which is closed airtight the fuel and the air (the mixture) compression it does. The mixture which was compressed is ignited, explodes burns. Burning, it depends on the heat energy which the combustion gas which it occurs hasExpansion piston and converts to kinetic energy. On opposite side of combustion chamber piston connecting rod・CrankshaftIt becomes the open part in order to remove with as rotational energy. water cooling engine the external wall or in the hollow section due to dual structureWater jacketForming, it cools. 2 cycle system scavenging is done by the hole intake port and the exhaust port which were opened to the cylinder. Inside cylinderHorning/honing processingIt is done, it keeps the lube which is supplied from crank side and in order for the piston to move smoothly, the lubrication it does.
piston engine is formed.
gasoline engine、 Diesel engine at one time with the part of the single unit, the tube of the cast iron make was general.Cylinder linerWith callingCylinder block(Cylinder jacket) Insertion casting at the time of the く/casting, it uses. Presently the cylinderCylinder blockWith the liner less system which is made the monobloc casting is permeating.Cylinder linerThe part which is suitable is superior in heat dissipation characteristic, piston ring and affinity are high (in many cases ceramics particle) it is plating. Because it is possible, to make the piston and the cylinder with the same aluminum, heat expanding, clearance is maintained and contributes to the improvement of engine output. The durability of the plated part it is above the cast iron, to maintain horning/honing processing which is administered to the surface it continues to end of engine life.
In order reduction of number of articles and to assure the improvement of rigidity, there is also a crank upper case and an engine which casts cylinder block just, is called 3 piece engines and the like.
The engine for the ship the cylinder & the piston is enormous, in order efficiently to be able to acquire big output in the cylinder where it fills up the mass air, quite is long and is thick it is devised.
