A cylinder in which a piston is guided for linear reciprocating motion of the cylindrical metal parts. The working fluid through the expansion cylinder of the engine is converted to thermal energy mechanical energy; compressed gas receiving a piston to increase the pressure in the compressor cylinder. Turbine engines, rotary piston housing often referred to as "cylinder." Cylinders have Nikasil cylinders, Chainsaw cylinder, Aluminum alloy engine cylinder. Chainsaw cylinder cylinder applications: Printing (tension control), semiconductors (spot welding, grinding chips), automatic control, robotics, and so on. In addition to the use of high-carbon material cylinder pipe, but still with a high strength aluminum alloy and brass. Small cylinders have to use stainless steel pipe. Cylinder or cylinders in corrosion environments with auto switch cylinder should use stainless steel, aluminum or brass and other materials.
Aspects of engine material, usually people often talk about the main cylinder block and cylinder head material, such as aluminum engines often said, refers to the cylinder block and cylinder heads are made of aluminum alloy casting. Talk about the cylinder. Just said ust said aluminum alloy engine cylinder naturally aluminum alloy, naturally aluminum alloy, in fact, incomplete right. Most of the "aluminum" should use cast iron cylinder liner engine, the reason behind the talk. We take a look at Aluminum alloy engine cylinder and cast iron cylinder block their advantages and disadvantages.
1) Weight: the proportion of aluminum is lighter than cast iron, under the premise to meet the strength requirements, the aluminum cylinder block is much lighter.
2) Volume: For the same reason, light weight aluminum, aluminum structural strength per unit volume is less than cast iron, so instead of aluminum cylinder volume is usually bigger.
3) corrosion resistance and strength: easily generated during combustion of aluminum and chemical effects of water, the corrosion resistance of cast iron, is less than the cylinder, particularly for higher temperature and pressure are especially supercharged engines.
4) Cost: Cost is naturally more expensive aluminum cylinder block, no interpretable.
5) antiknock properties: thermal conductivity of aluminum is faster, so the good cooling performance, the engine can help to reduce the probability of occurrence of abnormal combustion, the same compression ratio, the lower the aluminum cylinder engine can use the label than the cast iron cylinder gasoline engine.
6) Friction coefficient: the current engine, in order to reduce the inertia of the reciprocating parts, improving speed and response speed of the aluminum alloy is often used as the material of the piston.
