The internal combustion engine operates on the basic principle as its name implies, internal combustion engines have four-stroke four basic steps that repeat with every two revolutions of the engine: (1) Intake stroke / exhaustion (2) The compression stroke (3) Power / expansion stroke and (4) Exhaust stroke 1 intake stroke: The first stroke internal combustion engine is also known as the suction stroke because the piston moves to the maximum volume position (downward direction in the cylinder) create a pressure drop. The inlet valve is opened as a result of the cam lobe presses down the valve stem, and the vaporized fuel mixture is drawn into the combustion chamber. The inlet valve closes at the end of this stroke. 2 compression stroke:…show more content…
During this movement, the piston begins its movement in the position of maximum volume. The open exhaust valve allows exhaust gases to escape from the cylinder. At the end of this movement, the exhaust valve closes, the inlet valve opens, and the sequence is repeated in the next cycle. Four-stroke engines require two revolutions. Many engines overlap these steps in time; turbine engines do all steps simultaneously at different parts of the engines. Disadvantages: The lack of lubrication system that protects the engine parts against wear. Consequently, 2-stroke engines have a shorter life. • 2-stroke engines are less fuel efficient and produce more pollution than 4-stroke engines • Sometimes part of the fuel leaks to the exhaust with exhaust In conclusion, based on the advantages and disadvantages above, the two-stroke engines are supposed to operate in vehicles where the engine weight should be small and not used continuously for long periods.

Take a V-8 engine, for example. A V-8 engine has eight cylinders. Whenever the engine is running, the eight of these cylinders are working, burning fuel and air. Most cars, trucks and SUVs with V-8 engines have them because the cylinders of an engine usually has, the more powerful it is. That 's why V-8 engines in sports cars or heavy trucks are usually observed. But while people like V-8 engines, as they are fast and can pull heavy loads, most people are not doing things all the time. That is where comes into cylinder deactivation. Cylinder deactivation number of engine cylinders is closed when not needed. This means that when a car or truck is to maintain a constant speed and not speed, some cylinders are not in use. Since they are not in use, they are not getting any gas or - and saves fuel. Cylinder deactivation technology has been used in cars and trucks that run on V-8 in recent years, but some car manufacturers are starting to add to their six-cylinder engines, too. It is estimated that the cylinder deactivation technology can improve engine efficiency by 7.5
