List the major parts and sub parts of an automobile and describe the function of each one of them briefly? Since the exhaust gases are at higher pressure than atmospheric pressure, the exhaust system has to reduce the pressure of exhaust gases so that there is no noise on discharge to atmosphere. Cooling system circulates coolant Combination of water and a chemical through the engine components which absorbs the heat and transfers the heat to the atmospheric air through a heat exchanger. If the engine is going to operate, the fuel and air mixture must be fed into the combustion chamber. The burnt gases also must be exhausted.

List the major parts and sub parts of an automobile and describe the function of each one of them briefly? Since the exhaust gases are at higher pressure than atmospheric pressure, the exhaust system has to reduce the pressure of exhaust gases so that there is no noise on discharge to atmosphere. Cooling system circulates coolant Combination of water and a chemical through the engine components which absorbs the heat and transfers the heat to the atmospheric air through a heat exchanger.

If the engine is going to operate, the fuel and air mixture must be fed into the combustion chamber. The burnt gases also must be exhausted. To accomplish this, there is a passage to the combustion chamber called the intake port, and a passage from the combustion chamber to the exhaust system called the exhaust port. A diesel engine uses the internal combustion process to convert the energy stored in the chemical bonds of the fuel into useful mechanical energy.

This occurs in two steps. First, the fuel reacts chemically burns and releases energy in the form of heat. Second the heat causes the gasses trapped in the cylinder to expand, and the expanding gases, being confined by the cylinder, must move the piston to expand. The reciprocating motion of the piston is then converted into rotational motion by the crankshaft. To convert the chemical energy of the fuel into useful mechanical energy all internal combustion engines must go through four events: intake, compression, power, and exhaust.

How these events are timed and how they occur differentiates the various types of engines. All diesel engines fall into one of two categories, two-stroke or four-stroke cycle engines. The word cycle refers to any operation or series of events that repeats itself. In the case of a four stroke cycle engine, the engine requires four strokes of the piston intake, compression, power, and exhaust to complete one full cycle.

By putting openings in the combustion chamber, a problem is created; the force of the burning fuel and air mixture will be lost through the exhaust and intake ports rather than used to push down the piston. To solve this problem, there must be something that opens and closes the intake and exhaust ports to the combustion chambers. To accomplish this, a valve is. A simplified arrangement is shown in following figure.

Each time the piston moves from top dead centre to bottom dead centre, or vice versa, it completes a movement called a stroke. Therefore, the piston completes two strokes for every full crankshaft revolution. There are four definite phases of operation that an engine goes through in one complete operating cycle. Each one of these operating phases is completed in one piston stroke. Because of this, each operating phase is also referred to as a stroke and, because there are four strokes of operation, the engine is referred to as a four stroke cycle engine.

Like the four-stroke engine, the two-stroke engine must go through the same four events: intake, compression, power, and exhaust. But a two-stroke engine requires only two strokes of the piston to complete one full cycle. Therefore, it requires only one rotation of the crankshaft to complete a cycle. This means several events must occur during each stroke for all four events to be completed in two strokes, In a two-stroke engine the camshaft is geared so that it rotates at the same speed as the crankshaft.

The power of a two-stroke engine is usually double that of a four-stroke engine of comparable size. First Stroke During the first stroke, as the piston moves up from the BDC Bottom dead centre , it closes all the three ports, namely the inlet, transfer and exhaust ports.

The piston compresses the mixture of petrol and air inside the cylinder. Second stroke During the second stroke, the piston moves down from the TDC top dead centre And the inlet port is closed. The fuel mixture is compressed by the bottom of the piston and the crank. It then gets pushed into the cylinder through the transfer port. In a four-stroke engine the camshaft is geared so that it rotates at half the speed of the crankshaft.

This means that the crankshaft must make two complete revolutions before the camshaft will complete one revolution. During the exhaust stroke, the inlet valve is closed and the exhaust valve is opened.

When the burnt gas is pushed out of the cylinder, the exhaust valve closes. These engines are widely used in vehicles, portable power plants it supply the power to run pumps and other machinery on farms. Many small boats, aero planes, trucks and buses also use it. The four-stroke cycle of an internal combustion engine is the cycle most commonly used for automotive and industrial purposes today cars and trucks, electrical generators, etc.

The volume displaced by all pistons while moving from top to bottom. Also indicate in Litres. It could be push rod type or overhead camshaft type.

It could be gear driven, chain driven or belt driven. The cycle of operations of four-stroke engines is completed in two turns of the crankshaft. With such an operating cycle, the crankshaft receives energy from the piston only during one half its turn when the piston moves on the power stroke.

During the remaining three half turns, the crankshaft continues to revolve by inertia and, aided by the flywheel, it moves the piston on all its supplementary strokes — exhaust, intake, and compression.

The order in which like piston strokes occur in the engine cylinders is known as the firing order. For a multi-cylinder engine to run uniformly, the spaced rotationally at one and the same crank angle i. To find this angle, the duration of the engine cycle, expressed in degrees of crankshaft rotation, is divided by the number of the engine cylinders. The crank throws of the first and fourth cylinders are arranged on one side of the crankshaft, and those of the second and third cylinders, on the opposite side.

Such a shape of the crankshaft provides for even firing intervals and a good engine balance, since all the pistons simultaneously reach their extreme positions two pistons reach their TDC at the same time as the other two reach BDC. The firing order of the four-cylinder engines is usually This means that after the piston in the first cylinder has completed its power stroke, the next power stroke occurs in the third cylinder, then in the fourth cylinder, and finally, in the second cylinder.

When selecting a firing order for a particular engine, designers try to distribute the load on the crankshaft as uniformly as possible. The firing order of eight-cylinder four-stroke engines is 8 and that of six- cylinder ones, Knowing the firing order of an engine, one can correctly connect the ignition wires to the spark plugs and adjust the valves. An internal combustion engine is any engine in which the fuel is burned from within.

A four stroke cycle engine is an internal combustion engine because the combustion chamber is located within the engine. Open navigation menu. Close suggestions Search Search. User Settings.

Posted by: Juliet Onyeachonam. Although almost everyone drives or is driven in a car on daily basis, most people do not know the basic car parts names and their functions. For an average person, a car is just a piece of metal on four wheels for getting around. In actuality, a car is more than just metal and wheels. A car is made up of several component parts that work together to deliver power and eventual mobility to the car. In this article, Naijauto.

 - Сьюзан пожала плечами, демонстрируя равнодушие. - Мы с ним какое-то время переписывались, - как бы невзначай сказал Хейл.  - С Танкадо. Ты знала об. Сьюзан посмотрела на него, стараясь не показать свое изумление. - Неужели.

 Ты сочтешь это сумасшествием, - сказал Беккер, - но мне кажется, что у тебя есть кое-что, что мне очень. - Да? - Меган внезапно насторожилась. Беккер достал из кармана бумажник.

 Господи Боже мой, Сьюзан, с тобой все в порядке. Она встала на ноги и расправила платье. - Все обошлось.

Стратмор молчал. Положение оказалось куда серьезнее, чем предполагала Сьюзан. Самое шокирующее обстоятельство заключалось в том, что Танкадо дал ситуации зайти слишком. Он должен был знать, что случится, если АНБ не получит кольцо, - и все же в последние секунды жизни отдал его кому-то.
