Cylinder located on the engine block. Block machine are usually made of gray cast iron. Because the gray cast iron resilient wear pretty well other than that the price is quite cheap. As a comparison. Channel cooling water (water jacket) printed in the engine block and surround each cylinder. Several types of machines used in the cylinder liner insert (pressed) into the engine block, so it can be replaced when worn. This
system is called system wet liners (if outside the cylinder liner walls
in direct contact with the cooling water) and dry liners (if the outer
cylinder wall liners are not in direct contact with water cooling). Aluminum
alloy now more and more used as engine blocks, especially for machines
that are small, with the aim to reduce the weight, so it will get the
power to weight ratio is good.
Crankshaft (crankshaft / crankshaft)Crankshaft (crankshaft / crankshaft) are usually made of steel forgings (forged steel). Nodular cast iron can also be used as a crankshaft on light duty machines. Crankshaft fitted on the engine block and is supported by main bearings. Maximum Number of games bearing + 1 is the number of cylinders. Crankshaft has eccentric shafts, commonly called crank throw. Connecting rod (connecting rod / piston handlebar) mounted on each crank throw. On each play bearing and journal bearing mounted crankthrow (metal) made of bronze, Babbit, or aluminum. Crankcase
(non crankshaft) closed at the bottom of the oil pan (crankcase) which
is made of cast aluminum or pressed steel plate. Oil pan serves as a reservoir for oil lubrication system.
Piston (piston)Piston (piston) is made of aluminum alloy, while the big machines low speed usually made of cast iron. Serves
as a divider piston cylinders simultaneously transmits pressure
combustion gases into the crank throw by means of connecting rod. Connecting rod is usually made of steel or other alloy materials (aluminum, titanium, etc.). Connecting rod attached to the piston by means of piston pin is made of steel. Piston pins are usually hollow to reduce weight. Piston
rings are usually equipped with a piston that serves as insulation so
that the combustion gases from leaking into the crankcase as well as
serve as a regulator of the flow of oil to lubricate the cylinder walls.

| Cylinder head |
Cylinder head (cylinder head)Cylinder head (cylinder head) function to close the cylinder, and is made of an alloy of aluminum or cast iron. Cylinder
head must be strong and rigid so that the forces of the combustion
gases acting to the cylinder head can be distributed evenly to the
engine block. These
components consist of the spark plug cylinder head (for motor gasoline)
or fuel injectors (for diesel) and the components of the valve
mechanism.

Valve |
Valve (valve)Valve
(valve) is usually made of forged alloy steel (forged alloy steel) or
ceramic (the development / research engineers in mercedes benz). Cooling the exhaust valve that operates at temperatures around 700 ° C can be achieved by filling the holes sodium valve stem. With the process of evaporation and condensation of sodium to dissipate heat from the hot valve head to the valve stem cooler. Valve stem moves up and down in the valve guide (valve bushing). A
spring valve mounted on each valve stem by using a spring washer and
split keeper, who serves in order to hold the valve remains closed.Camshaft (camshaft / cam shaft) are made of cast iron or steel forgings and each cam serves to open or close the valve. Cam surface that is usually toughened its wear resistance increases. For motor 4 stroke, camshaft rotational speed is half of the crankshaft rotation speed
