COMPONENTS OF INTERNAL COMBUSTION ENGINE Even though reciprocating internal combustion engines look quite sim¬ple‚ they are highly complex machines. There are hundreds of compo¬nents which have to perform their functions satisfactorily to produce out¬put power. The main components of the IC engine and their functions are described below. • Cylinder Block: The cylinder block is the main supporting structure for the various components. The cylinder of a multi-cylinder engine is cast as a single

structure is made up of a thick‚ stretchy muscular wall‚ they have a narrow central tube and they contain no valves. Arteries branch into smaller tubes called arterioles and then into capillaries. Their main function is to carry oxygenated blood. Veins carry blood towards the heart. Its structure is made up of thin walls with little muscle‚ they have a wide central tube and they also contain valves. Veins branch into venules and then into capillaries. Veins main function is to carry deoxygenated blood

This is because water supplied is hard water since it contains a lot of calcium‚ magnesium or other minerals. Water hardness Mg/L Soft water ≤ 17.1 mg/L Grey zone between soft and slightly hard water 17.1-60 mg/L Moderately hard 60-120 mg/L hard water 120 - 180 mg/L Very hard water ≥180 mg/L Hard water causes two problems such as 1.

1. A reciprocating engine automatic mixture control responds to changes in air density caused by changes in Altitude or temperature 2. On a float-type carburetor‚ the purpose of the economizer valve is to Provide a richer mixture and cooling at maximum power output 3. The fuel metering force of a conventional float-type carburetor in its normal operating range is the difference between the pressure acting on the discharge nozzle located within the venture and the pressure Acting on

Atrioventricular valve caused by ventricular contraction. The R wave occurs during the depolarization of the ventricles. Hence the lub sound occurs because of both the depolarization and consequently the closing of the AV valves which prevent blood flow back into the atria.

sealed fuselage by cabin superchargers‚ which deliver a relatively constant volume of air at all altitudes up to a designed maximum. Air is released from the fuselage by a device called an outflow valve. Since the superchargers provide a constant inflow of air to the pressurized area‚ the outflow valve‚ by regulating the air exit‚ is the major controlling element in the pressurization system. It is necessary to become familiar with some terms and definitions to understand the operating principles

Matt Bagley English 110 Process Essay Process of a 4-stroke Internal Combustion Engine A common phrase that is heard whilst growing up is "curiosity killed the cat". This phrase might be true but; "ingenuity brought the cat back". Having a mindset in which giving up is never an option has plagued most inventors of the modern day‚ especially a high school drop out named Nikolaus August Otto‚ born in 1832. Otto was responsible for the development and improvement of the 4-stroke motor that
