4 stroke engine video download
The engines with are generally used in our car or bike is a four stroke engines. Earlier two stroke engines were also used in scooters and motorcycles but now they are downloac obsolete. For successful operation, an Engine has to complete a sequence of operations free poker software download a cycle. In case of four stroke engines, the operations which form a cycle are as follows. This animation shows all the five operations mentioned above in the four strokes. In this animation blue color represents fresh charge and brown color represents exhaust gases.
There are different types of enginesand a 4-stroke engine is one of them.
Four Stroke Engine
According to the number of piston strokes, the engines have two major types that are:. In the previous article, we discussed the 2-stroke downlowd. Therefore, in this article, we will mainly discuss the four-stroke engine. A 4-stroke engine is an IC engine that uses four strokes of the piston to complete a working cycle.
How does a 4 stroke engine work ? – MechStuff
It converts the thermal energy of the fuel into useful mechanical work due to the upward and downward movement of the piston. Therefore, it belongs to the category of the reciprocating engine. A four-stroke engine completes a power cycle after the completion of dowmload revolutions of the crankshaft and 4 strokes of the piston.
These engines are most widely used in different vehicles such as light trucks, buses, vans, cars, etc. In this reciprocating engine, the compression process occurs due to the up and down movement of the piston. The main difference between the 2-stroke and 4-stroke engines is that a 2-stroke engine completes a working cycle in just two strokes while a four-stroke engine completes a working cycle in four strokes of the piston.
A 2-stroke engine produces less pollution compared to a 2-stroke engine.

What is a 4-stroke Engine and How its work? [With PDF & Animation]
The out power of the engine depends on the amount of air drawn in. The performance of a piston engine whether it is a 4-stroke engine or a 2-stroke engine depends on the speed RPMthe calorific value of the fuel, loss, air-fuel ratio, volumetric efficiency, oxygen content in fuel-air mixture and combustion chamber size. Ultimately, the speed of the engine controls through lubrication and material strength.
The connecting rodpistonand valve of the engine face strong acceleration forces. High engine speeds can lead to engine damage, loss of power, piston ring flutter, or other physical damage. When the piston ring vibrates vertically in the piston groove in which the viddo ring is located, the piston ring flutters.
The stroks of the ring flutter is to settle the seal between the cylinder wall and the ring, which leads to a loss of power and pressure in the cylinder. If the engine turns too fast, the valve spring will not be able to close the valve fast enough. The four-stroke engine has downloar following major components:.
The piston in the 4-stroke diesel engine produces reciprocating movement. It connects with the crankshaft via a connecting rod. It transfers its motion to the crankshaft via a connecting rod.

The piston moves downwards and upwards inside the cylinder of the engine. When the piston moves up, it sucks the air inside the cylinder, while it compresses the air when it moves downward. Due to this piston movement, the temperature and pressure of the air-fuel mixture inside the cylinder increase.
The engine piston has a complex construction with a steel crown and a ductile cast iron skirt. This skirt uses pressure lubrication to ensure oil delivery to the cylinder liner underneath each working situation. Oil feds toward the cooling duct at the top of the piston down,oad the connecting rods.

All piston rings are chrome-plated to resist wear. The piston ring contains a spring-compatible downlad control ring engibe 2 guiding compression rings. The piston ring groove has excellent wear resistance and is stabilized. This component of the four-stroke engine has a high, rigid collar to lessen deformation.
This linear material is a gray cast iron alloy with high strength and brilliant wear resistance. Precisely placed vertical cooling water holes ensure precise temperature control. To avoid the bore polishing risk, the linear equips with a protective polishing ring.Four stroke engine 3d animation on Vimeo
The space among the cylinder liner and the cylinder block seals with a double O-ring. In reality, the components often have highly complex and irregular shapes.

Since a realistic rendering might obscure the underlying process I have reduced the components to their simplest form. Car engines have multiple cylinders contained together in an engine block.· A 4-stroke engine is an IC engine that uses four strokes of the piston to complete a working cycle. It converts the thermal energy of the fuel into useful mechanical work due to the upward and downward movement of the piston. Therefore, it belongs to the category of the reciprocating engine. A four-stroke engine completes a power cycle after. · The four stroke engine is probably the most common engine type nowadays. It powers almost all cars and trucks. Speed 10 fps. The four strokes of the cycle are intake, compression, power, and exhaust. Each corresponds to one full stroke of the piston; therefore, the complete cycle requires two revolutions of the crankshaft to complete. A four-stroke engine is an Internal combustion engine, where four successive strokes (i.e. Suction-Compression-Power-Exhaust) completes in two revolutions of the giai-mong.coore, the engine is called a Four-stroke engine.. In recent days the majority of automobile runs on a four-stroke cycle. Basic some terms used in this article.
Usually these contain 4, 6 or 8 emgine. For example a V6 engine contains six cylinders arranged to create a V configuration. The piston moves down and the petrol air gasoline-air mixture enters the cylinder. The inward flow of the air-fuel mixture is illustrated as a rotating spiral entering the engine through the purple inlet.
The piston then moves upwards and compresses the air-fuel mixture. The sparking plug spark plug then fires an electrical discharge and the compressed mixture explodes by contrast, diesel engines stgoke the heat of compression to ignite the mixture. This explosion drives the piston downwards in what is called the power stroke.
The piston then returns to the top of the cylinder in the exhaust stroke and drives the exhaust gases out of the engine.
