2013 MOTORCYCLE Block Cylinder Engine

Block Cylinder Engine
Well our discussion this time is about the cylinder block, both the cylinder block what it is, let us see

Cylinder liner and the cylinder block is a two-part attached to each other. Power of a motor is usually expressed by a cylinder the size of the motor. Cylinder liner is securely fastened to the block, and the material is not the same. Cylinder liners are made of materials that resist against friction and heat, while the block is made of cast iron heat resistant. In the beginning, there were designing into one, is rarely there. Now made ​​a separate mean cylinder liner its wear and tear can be replaced when it is excessive. The material is made ​​from gray cast iron. For mild motors like on a bike This bike is mixed with aluminum material. Materials selected blocks in order fulfill the terms of use are: Resistant to temperatures high, can conduct heat well, and is resistant to friction.

Figure 2 : Cylinder Block

Right in the middle of the cylinder block . Piston cylinder liner is coated materials specifically to prevent rapid wear due to friction . Despite receiving adequate lubrication cylinder bore wear but still did not can be avoided . Therefore long -term wear and tear are bound to happen . Cylinder bore wear and tear could have occurred by uneven so it can be keovalan or taper . Each such damages must be known to determine the repair steps .How to measure the wear of the cylinder :1 . Remove the cylinder block2 . Remove the piston3 . Measure the cylinder bore diameter with " dial indicator " section measured the top , middle and   bottom of the cylinder bore . Measurements were taken twice in cross position .4 . Calculate the magnitude keovalan and taper . Compare with provisions in the manual serve . If the magnitude keovalan and taper exceeds allowable limits cylindrical hole should diover size . Stages over size is 0.25 mm , 0.50 mm , 0.75 mm and 1.00 mm . Should first over size 0.25 mm to wear under 0.25 mm and so on . If the cylinder it is not possible in over size then the solution is with replaceable cylinder linings .

Table 1. Differences construction cylinder head and cylinder block
of two stroke engines and four-stroke

Construction outside the cylinder block is made like fins, this to heat release due to engine work. With the fins these will happen because the air cooling of the engine can be flows between the fins. The fins also expand the field of refrigeration, so the greater heat absorption and temperature of the motor is not too and in accordance with the high working temperature. Requirements cylinder that is both round and slippery pit from bottom to top, each of the walls there are no scratches which typically arises from a spring ring, piston is not loose (not beyond what has been specified), not cracked or broken. Differences construction and components of the cylinder head and block cylinder four-stroke engine and a two-cycle engine is shown by one table (Table 1)
Note:
• Hole-cylinder is the space where the piston moves.
• Hole filling (inlet port) is a fuel line from carburetor to the crank shaft under the piston.
• Hole flushing (transfer port) is where the material cylinder head combustion chamber above the piston head
• A drain hole (exhaust port) is a hole or channel to dispose of leftover or used combustion gases

 Enough of my friends discussion. great expectations of me to friends that want to submit comments and suggestions to my post. DO NOT JUST WANT copy and paste ONLY FRIEND. Much obliged.
