im mohammedali alrikabi im in english 101 at evcc I am also a running start student from high school graduating this year

I choose engine blocks as an article. this is up to date all the links should work. The grammar was perfect i do believe that the should include how its put together and the difference of rotary engines and normal piston engines. Cranksahft A counterweight for each cylinder is welded to the crankshaft and then ultrasonically examined to assure weld integrity. The crankshaft end flanges are identical to enable full power to be taken from either end of the engine. Pistons are a metal part that is found in the middle of the engine which cause the burning from the head to the crank the top part meet the valves which cause the fuel combustion burn and the bottom end connects to the crankcase which spins for the burning process using oil as a lubrication. The selection of materials for production of cylinder blocks depends on the type and function of the engine. Engine blocks are usually made from cast iron or aluminium alloys. In engines with the camshaft located low in the cylinder block, the camshaft can be driven directly from the crankshaft using only two gears. Though this drive system is simple. Cylinder head: bore-cooled flame plate; six hydraulically tightened securing bolts to ensure even distribution; new cooled exhaust valve seat. Engine blocks also have a cooling system which cool it down from overheating and having it seize. Engines make lots friction which cause heat without having it cool at certain temperature cause by a radiator which contains antifreeze. The engine running should be 160 to 220 Fahrenheit it can be lower but that means it either doesn't have thermostat or its not burning fuel right. If its higher than that a head gasket can crack and cause water and oil to mix but if it increases to 300 Fahrenheit or more the engine will seize. A seized engine is when the pistons and crankshaft all weld together causing it not to turn anymore. Which then is considered non reparable.
