Machine Parts

As a result of excessive fuel consumption may be occurred 1.       High float level or heavy or fuel soak. 2.       Dirty riddle valve. 3.       Worm jets of nozzle. 4.       Stuck metering rod/power piston 5.       Rich mixture/ high fast idle. 6.       Leaky carburetor. 7.       High fuel pump pressure. 8.       Leaky power valve diaphragm. 9.       Lack of engine power acceleration. 

Brakes: A car stop or slow brake is needed. Brake mechanism types: There two types of brake mechanism at the wheels i.                     The drum and shoe type. ii.                  The disk type. The drum and shoe type: Drum and shoe type brake system there have wheel brake cylinder with two pistons. When brake fluid is forced into the brake cylinder by the action at the master cylinder, the pistons are forced to outward. For this reason the curved brake shoes to move into contact with the brake   drum. The brake shoes apply friction to the brake drum, forcing it and the wheel to slow or stop. 

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.
