Engine characteristics

Engine is a mechanical type. The change of heat energy used to power the drive. , Called the heat engine. This is with several types

The heat engine is a 2.
1, internal combustion engines.
2, the combustion of automotive exterior.
2-engine and can be separated by the table below:

Engines used in cars. Must be small and lightweight. Because of the need to install a limited The capacity to produce a motorcycle and drive around to the other high-use And less noisy. With this engine gas engine petrol or diesel and Rock Lee. An internal combustion engine is the engine currently used in most cars.
Gas engine gasoline engine or Rock Lee.

1st shirt smoking (CYLINDER BLOCK).

Structure made of metal or alloy. Usually have the edge on the edge of the outer wall it helps to increase strength and cooling. Shirt pump includes a cylinder, piston set multiple mobile. And down inside. Top of the cylinder seal was a pump lid. Hermetical, with a pump lid gasket between Smoking and smoking rooms Shirt Cap crankshaft is the lower part of the shirt around the pump cylinder is found by evening.
Cold water and will be found through the channels with the internal lubricant pump shirt also includes a cylinder, piston move up. Mix fuel with air will not leak. And resistance of friction. Between the cylinder piston. Must be low as possible. Therefore, cylinders must be produced efficiently.

2, pump lid (CYLINDER HEAD).

Scum pump is installed above the pump shirt. The hidden room is burning. Cylinder wall and the tongue and swallow. Must be able to tolerate temperatures. And most are to come. From the operation of this engine with pump lid. Is made from cast iron or alloy Aluminum & ???? Pluto The evening performance is better than cast iron sculpture. Cap also includes pump. Cast cold water. Which articulate with cast cold water on the shirt smoking It also cast a cold pump lid. Also cast cold spark plugs.

3-cylinder (PISTON).
– Structure
Mobile piston up and down within cylinder To the duty charged on tempo ID. Compress the explosive mix. And spit out the most important functions of the exhaust cylinder is receiving pressure from the ignition, and this is sent to the crankshaft through the pump shaft. Cylinder was high-temperature heating and always do the most and Must be durable to run around the high over long periods of time. Typically made from cylindrical.
Aluminum alloy. This lightweight and efficient cooling better than other types of materials the name of spare parts. The piston is shown in the illustration below.

– Length of cylinder gap. (Distance between the piston cylinders).
When the piston is heated humid. It will expand slightly. The diameter is increased with this expansion in every period there is a gap between the cylinder piston in place at room temperature (25 g ?, 77, ?) now called the gap length cylinder This gap cylindrical phase shift depending on the type of engine. Period but will usually start from 0.02 to 0.12 mm (0.0008 to 0.0047 inch) cylinder is similar to a slender, small portfolio. Twist, center stage is a split cylinder head is smaller than the bottom of the cylinder slightly. Therefore phase space The piston is the most wide cylinder head. And most narrow at the bottom of the cylinder.

Phase spaces of the piston is measured different This depends on the type of engine repair manual view point to find a measure of gap cylindrical phase.

Period gap is very important plunger. Engine to run correctly and performance is better. If the gap distance is less. Gives no phase gap between the cylinder when the cylinder piston will cause the heating cylinder adjacent to the cylinder. The result can cause the engine to deteriorate. If the gap distance too. In contrast is the pressure caused by the ignition And pressure of gas
The burn is OK. Cause reduced engine performance.

– Piston ring (PISTON RING).
Ring customers will be the bow of the piston ring groove. Outside diameter size of the piston ring is slightly larger than the piston own when combined with the piston in the extended properties of the contractile ring, and it grew to a close attachment to the cylinder wall. Cylindrical metal ring to a high resistance to wear a special kind cast iron plate Projec Emie Pluto That will not scrape the piston ring is a trace amount of cylinder piston ring to vary by type of engine. The number is usually three to four balls, one ring per cylinder.

Piston ring has three major functions is The act prevents air leakage from the fuel and the gap between the piston cylinder. Rooms with crankshaft Rhythm during the implosion and explosion are two functions that prevent the lubricating oil on the side of the piston cylinder. Not to leak out into the room survived burn. The last page is Heat transfer from piston to cylinder wall. To piston cooling.

1) ring compression
This ring prevents leakage of compressed air and fuel mix and the gas generated by burning room packed between strokes. Point and not to explode into the room number of the crankshaft ring is compressed depends on the type of engine. Generally a child will have a piston ring which pumped two “ring on the recorder” and “ring-packed second” ring is compressed, the portfolio characteristics. Therefore, the lower edge of it touched the cylinder wall.
Design such as this to occur as close to the touch. Between ring and cylinder. It is also a sweep oil from the cylinder walls effectively.

Piston ring is the number “1″ or “2″ on it the number “1″ means that Ring and on the number “2″ is the second ring assembly, so this number must face up to the top

2) sweep the oil ring.
Oil ring sweep sweep Cause a film of oil needed to lubricate the surface between piston And cylinder wall. And sweep the excess oil. To prevent the oil drop to ring in the room burn oil sometimes called a sweep for the third ring are two types together. Oil-ring sweep includes the three-piece This three-piece is used.

(2.1) Total
Oil-ring sweep includes the known oil provide feedback. That size is around. And oil is known to be in accordance with this sweeping oil ring groove section that is sweeping over the ring by the fluid into the scourge known these And flow back into the interior of the cylinder.

(2.2), three-piece
Three-piece oil ring sweep includes. Sweeping side plates. To sweep out the excess oil, and the pressure plate to sweep close to the side.
Ring ring groove and cylinder oil sweep a three-piece. To act as a total

(2.3) spaces mouth ring
Piston ring to grow in the same manner as when the hot cylinder With this piston ring has a cut mouth. And when combined within the cylinder will be the appropriate spaces, called gap mouth ring Phase spaces will vary depending on the type of machine. But typically in the range of 0.2 to 0.5 mm (0.008 to 0.020 inch) at normal temperature.

If the gap distance is too large mouth ring. Will cause the engine is pumped out of phase if the mouth is too narrow ring. Engine can be made. Will be late because of the ring. Because of heat expansion. Make ring bent. Walls made out of cylinders.

4, pump shaft (CONNECTING ROD).
Shaft with piston pump with crankshaft And are transmitted to the crankshaft end of the pump shaft with a small cylinder called a late end to the remaining crankshaft called late in the crankshaft to rotate at speeds in the end. Cause high temperatures. To prevent. ? deterioration caused by heat by the end of it consists of large bearings. The oil and some
This surge of oil from known oil to the piston within the cylinder to cool.
Assembly to be coupled to pump shaft. Otherwise the oil will make caulk (the side of the piston. RIM draw ?? bound directly to the prevention of errors. Pump shaft is marked in each set, the operation is that different types of machines so as to make inspection Repair Guide for detailed

5th crankshaft (CRANKSHAFT).
Drive to drive wheels of the vehicle. By drawing down the shaft of the pump and the rotation of the crankshaft crankshaft receive power from the shaft and piston pump spin speeds for this reason it is made from carbon steel, high-mix tips. a high resistance to wear.

Structure of the crankshaft of the illustrations below.

Future, the woman is supported by bearings crankshaft crankshaft’s room and crankshaft rotate around the Future is the Future, woman, each woman has the arm of the crankshaft. The crankshaft is installed on the crankshaft to the center axis of the skew axis in the form of encumbrance. To reduce the unbalanced force of the crankshaft rotation. While working on the engine crankshaft is known for a lubricant oil to the Future girl. Pump shaft bearings. Pump shaft and fasteners.

6 wheel power assist (FLY WHEEL).
Momentum wheels do help with the heavy cast iron with ?? Doc, late, with the crankshaft. Transmission for vehicles that are used in a regular rhythm of the engine explosion point. The piston is transmitted to the crankshaft only single strokes. Perry that the addition of the tempo, rhythm this other is lost due to friction wheel inertia force will continue to help force rotation (Inertia) during the other strokes apart from the explosion strokes. Rotate the crankshaft to continue to also make the engine work smoothly with the surrounding teeth fertility cycle the edges of the wheel idle wind power will help tackle the teeth of the drive motor start fertility. While starting up the engine. Gears used in automotive automatic power assist wheel is changed, a textile, Convergent Counsel

“The loss of inertia” refers to the loss is especially resonant in the compressed This occurs while the piston is moved up pressure compressed air and fuel mix.
Crankshaft bearings.
1, General Chapter lecture.
Crankshaft has been doing serious strength. (Gas caused by the ignition, piston And rotate at high speeds. For this reason, bearings needed to support the use of the crankshaft and woman, and Future oil to prevent stickiness death and loss of stiffness.
2 types of bearings.
Crankshaft and other parts that rotate at speeds and under a weighty burden to use support-bearings. The bearings-this Features good tolerance to wear. Performance and prevent contamination death. Bearings cortex consists of a metal. And surfaces of bearings made of metal type. Experience with a crankshaft for a block of metal shell to protect bearings from rotating bearings.
This has produced a many – Each type of meat is the material surface with different functions around the other to a metal white metal Clevestig fat Or aluminum.

Bearings each number is set bearings. To change the bearings will need to change the bearings to match the number of numbers that are changing the way the original number selected bearings. To study the repair manual.
1) the white metal.
Metal white metal ????????? zinc coated with tin or lead coated materials. It is seized of the island. But because it has less strength. Therefore often be used in engines has been not much
2) metal Clevestig fat
UK, fat metal surface is coated with copper metal. And lead, which is mixed with more strength and resistance to hunting as well as the white metal. But the island has been confiscated poor. Metal, UK, with a fat engine crafty And heavy load.
3) aluminum metal.
Surface aluminum metal which has a surface aluminum Tin and mixed mantle. Effective resistance to wear. And cooling better than the white metal and the metal Clevestig fat which are used with gasoline engines.

3, the gap of the oil bearings.
Face contact between the bearings on the crankshaft to rotate the need to send a sufficient amount of oil to lubricate the polish to prevent direct metal to metal ???. Therefore need a suitable gap between the bearings on crankshaft Enough oil to create a film of oil. Gap is called Oil gap. The size will vary according to type of engine but the way around.

Size is from 0.02 to 0.06 mm (0.0008 to 0.0024 inch)

Mechanisms tongue

4 strokes engine coupled with packed strokes strokes strokes suck explosive spitting exhaust strokes. But work is only 2 strokes of the tongue is attached rhythm and spew exhaust steam. Therefore, the mechanism design tongue To such work is 1 Rotate the cam shaft to run word of ID. Tongue and exhaust cam shaft to the second round will be 1 full duty work.
Flywheel ?? Times cherished possession. Will be combined in one end of the crankshaft. The flywheel ?? Times cherished possession of the cam shaft will seize on the end of the cam shaft. Exhaust cam shaft with the crankshaft is driving the belt. ID is the cam shaft drive gear that is the stickiness with ID and exhaust cam shaft (note from the picture above) the number of flywheel teeth ?? Times cherished possession cam shaft. Are many.
2 times the flywheel ?? Times cherished possession crankshaft cam shaft is rotated around the crankshaft rotate 1 Round 2 of the tongue will work balance And correct the rhythm of work. Will make the engine run efficiently. Tongue mechanism will vary depending on the engine in the system. We will illustrate the following

And do not require lubrication. Or adjust the belt tenseness also has less weight. How to drive a different word for this reason the engine is currently used in most

7th to sink oil ?? Stores (OILPAN).
Basin oil mentioned in a final order of the parts of a machine.

The bottom of the shirt called pump crankshaft The basin is an oil and stickiness is coordinating with liquid gasket or rubber gasket or packing paper. Basin oil to a steel plate. Block plan, and act ??? oil. Sink to the bottom when the car is not on the level and ??? speak out when the brake pedal in the immediate The gas station can be made to send oil to lubricate at all times. The oil will be filmed in the movie section of the basin bottom.
Basic principles of the engine 4 strokes

Resonant charge ID.
The rhythmic cadence of the air. And fuel into the cylinders, which are pulling tongues ID exhaust opening while closing word. As the piston moved down. Vacuum will occur in the cylinder and the mix of air and fuel is driven into the cylinder by atmospheric pressure.
Tempo jam
This is the rhythm, tempo of air and fuel is pumped. Both tongue and palate exhaust vapor tight engine while moving from bottom dead center to dead center will be pumped on the mix makes the pressure and temperature are increased to the point of explosion crankshaft one full rotation. when moving it around to center on death.
Cadency point explosion.
This rhythm is the rhythm engine powered car in production is due before the piston is moving to zero in on death strokes recorder will spark the spark plugs fire to the mix of air and fuel resulting in burn insurgency quickly. cause the gas pressure cylinder pressure to force a draw down.
This is the machine is motoring!
Spew exhaust strokes.
The rhythm of this gas will be burned exclusion from cylinders. Exhaust open and tongue out from the piston is moved up dead center to bottom dead center. Driving exhaust gases from the cylinder when the piston top dead center and moving it will start to charge ID rhythm again. Described from this point until the crankshaft rotate twice. And the engine will be a fully working routine. Quaternary cadency Cadency ID is attached packed ingredients. Explode and spit out the exhaust. This is the basic work of the four engine strokes.
Lubrication system.
Engine consists of a moving metal parts in many parts, each of which will combine the decidedly Those parts include pump shaft and crankshaft parts
Mechanisms tongue
When the engine starting rotation. Friction between these parts causes are job losses erode As well as the stickiness of the engine. Due to heat from the grate. Therefore, lubrication is sent to those parts. To prevent unwanted symptoms of them. The lubricant was sent pay.
The engine’s lubrication system that Picture below shows the mechanism of lubrication while the spin axis.

Role of lubricant
1) will create a coating of lubricant oil over the surface of metal joint To prevent exposure. Direct metal It also reduces traction to occur least And to prevent wear. And the heat.
2) allows parts of the engine oil cooling.
3) enables the prevention of oil leakage between the piston And a cylinder.
4) bring oil from the engine grime.
5) oil prevent parts from corrosion.

Type of lubrication system.
Oil is sent to pay the moving parts of the engine such as a multiple-pressure-??? as a whip and sprinkle with a pressure ??? together. The only way a pressure is applied to the motor current. In-pressure lubrication system. Oil pressure is caused by a gas station and send forces to the movement of engine parts.

The flow path of a lubricating system pressure as shown in the illustration below.

Gas Stations.
Station suck up oil from oil basin. Make the oil pressure up and down to the movement of engine parts. Sometimes ??? will be driving the crankshaft and the sometimes eccentric shaft or belt to get a rude filter will be installed at the entrance of the petrol station to filter out dirt, oil
