Figure : Classification of engines by cylinder arrangement 1. Double- acting engine: the fuel burns on both sides of the piston figure 1 — 8. Cylinders may be vertical or horizontal, vertical engines needs smaller area, when area is available horizontal engines may be used, this would make all engine parts accessible and the operation and maintenance are easier. Classification by valves Location: The most popular design is the overhead-valve design, there are also an under head valve engines and a combination of the two designs is also used see figure 1 — 9.

Figure : Classification of engines by valve location 8 Use of the Engine: 1. Marine engine: for propulsion of ships at sea. Industrial engine: for power generation on land. Automotive engine: for transport.

Method of Cooling the Engine: 1. Water- cooled engines.

Air- cooled engines. The Continuous- Combustion Gas Turbine: The main components of the gas turbine are; a compressor, a turbine and a combustion chamber, see figure 1 — In operation, air is drawn into the compressor, compressed, and then passed, in part, through the combustion chamber.

The high- temperature gases leaving the combustion chamber mix with the main body of air flowing around the combustor.

This hot gas, with greatly increased volume, is led to a nozzle ring where the pressure is decreased and therefore Figure : Diagrammatic sketch of gas turbine the velocity is increased. The high- velocity gas is directed against the turbine wheel and the K. Engine Parts and Details: The main components of the reciprocating internal combustion engine are shown in Figure Engine parts are made of various materials and perform certain functions, some of which will be explained: cylinder block g it is integral with crank case m , both are made of cast iron.

The piston e reciprocates inside the cylinder, which include the combustion chamber. This end of the connecting rod is known as small end. The other end of the connecting rod called the big end is connected to the crank arm by crank pin l. Camshaft u makes the cam t to rotate and move up and down the valve rod through the tappet r.

Mainly each cylinder has two valves; one is admission or suction valve and the other is exhaust valve. The ignition system consists of a battery, an ignition coil, a distributor with cam and breaker points, and spark plug for each cylinder. In diesel engines there is an injection system instead of ignition system. Cylinder bore B : The nominal inner diameter of the working cylinder.

Piston area A : the area of a circle diameter equal to the cylinder bore. Top Dead Center T. In the case of the horizontal engines this is known as the outer dead center O. Bottom Dead Center B.

In horizontal engine this is known as the Inner Dead Center I. Figure : Piston and cylinder geometry 12 CHAPTER 2 Air Standard Cycles During every engine cycle, the medium changes sometimes it is a mixture of fuel and air or products of combustion, the specific heats and other properties of the medium change with temperature and composition.

The accurate study and analysis of I. To simplify the theoretical study "Standard Air Cycles" are introduced, these cycles are similar to the open cycles, but some simplifying assumptions are made: 1.

Cylinder contains constant amount of air and it is treated as ideal gas. The specific heats and other physical and chemical properties remain unchanged during the cycle.

Instead of heat generation by combustion, heat is transformed from external heat source.

The process of heat removal in the exhaust gases is represented by heat transfer from the cycle to external heat sink. There is neither friction nor turbulence; all processes are assumed to be reversible. No heat loss from the working fluid to the surroundings. Cycles can be presented on any diagram of properties. The Otto Cycle constant Volume : These cycles is applied in petrol or gasoline engine, gas engine, and high speed diesel oil engine.

The typical piston design is on the picture. This type of piston is widely used in car diesel engines. According to purpose, supercharging level and working conditions of engines the shape and proportions can be changed.

The pin itself is of hardened steel and is fixed in the piston, but free to move in the connecting rod. A few designs use a 'fully floating' design that is loose in both components. All pins must be prevented from moving sideways and the ends of the pin digging into the cylinder wall, usually by circlips. Gas sealing is achieved by the use of piston rings. These are a number of narrow iron rings, fitted loosely into grooves in the piston, just below the crown. The rings are split at a point in the rim, allowing them to press against the cylinder with a light spring pressure.

Two types of ring are used: the upper rings have solid faces and provide gas sealing; lower rings have narrow edges and a U-shaped profile, to act as oil scrapers.

There are many proprietary and detail design features associated with piston rings. Pistons are cast from aluminium alloys. For better strength and fatigue life, some racing pistons [1] may be forged instead.

Billet pistons are also used in racing engines because they do not rely on the size and architecture of available forgings, allowing for last-minute design changes.

Although not commonly visible to the naked eye, pistons themselves are designed with a certain level of ovality and profile taper, meaning they are not perfectly round, and their diameter is larger near the bottom of the skirt than at the crown.

To produce pistons that could survive engine combustion temperatures, it was necessary to develop new alloys such as Y alloy and Hiduminium , specifically for use as pistons. A few early gas engines [i] had double-acting cylinders , but otherwise effectively all internal combustion engine pistons are single-acting.

Although compact, for use in a cramped submarine, this design of engine was not repeated. Trunk pistons[ edit ] Trunk pistons are long relative to their diameter. They act both as a piston and cylindrical crosshead.In modern petrol engines r reaches a value of Jump to Page. Mathur and R.
