Machine Parts

Steering system: The steering system permits the front wheel s to be pivoted on their supports to the right or left so that the car can be steered.  Power train: The power train contains several mechanisms which carry the engine power to the rear wheels. And they are clutch, transmission, propeller shaft, differential and rear axles.  Differential: A car differential contains gears that carry the driving power from the propeller shaft to the rear wheels can rotate different amounts when the car goes around a turn.     

Lubrication system: In a lubrication system there have many moving parts in the engine. Lubricating oil protect the moving parts so that there will be no actual metal to metal contact. The moving parts in effect float on films of oil. Lubricating oil covered the surfaces of the moving parts to prevent metal to metal contact and undo wear of the parts.  Frame and Chassis: A frame is required to support the engine, car body, wheels and other car components. Frames are made of channel or U shape, sections, welded or riveted together. Cross braking makes them rigid enough to withstand the shocks, blows, twists and vibrations all of these occurred in operation. 

Engine Cooling system: By the burning of air fuel mixture heat is produced in the engine. A small amount of heat escapes from the engine through the exhaust gases. If these heat is removed by using others metals or way it may make serious trouble in the engine. When the engine is running the water takes heat from the engine, becoming hot in the process.                                                 Figure: Open IC engine Cooling System   A water pump pumps the hot water from the engine water jackets into the radiator. The radiator has the two sets of passages. One set carries water. The other sets carries air. As the water passes through it gives up its heat to the air passing through. The cooled water then reenters the engine, where it can pick up more heat. In operation water continuously circulates between the engine and radiator, carrying heat from the engine to the radiator. By this ways excessive heat is removed.                

Ignition System:  Ignition system is a part of electric system of the automobile engineering. It purpose to create high voltage about 20,000 volts and to deliver this high voltage to the combustion chamber in the engine. These high voltage surges then cause electric spark in the combustion chambers. The spark ignite or set fire to the air fuel mixture in the combustion chambers so that it burns and causes the engine to operate.  What are the basic parts of an ignition System? Ignition System basic parts: There are three basic parts of a ignition system : i.                      The spark plug. ii.                    The ignition coil iii.                   The ignition distributor. 

Mechanical Fuel Pump: Mechanical fuel pumps which is mounted on engine. It contains an airtight, flexible diaphragm attach which is linkage to a rocker arm. The rocker arm rests on offset or an eccentric, section of the engine camshaft. When the engine is running, the rocker arm to back and forth by the eccentric forces for this reason the diaphragm to move up and down.   As a result a pumping action that pumps gasoline from the fuel tank to the carburetor.  Electric Fuel Pump: Electric fuel pump which is mounted on inside of a fuel tank. It is uses electricity from the battery or alternator to operate a plunger, bellows, diaphragm and impeller. As a result pump can supply fuel to carburetor from fuel tank.  Carburetor:    The carburetor is a necessary to a mixing device which mixes liquid gasoline with air. In the fuel system it throws a fine spray of gasoline into air passing through the carburetor on its way to the engine. T
