The Engineers Crib

The compression ignition engine[C.I engines] also known as the diesel engine is invented by Dr. Rodolph Diesel. The C.I engine is an internal combustion engine in which combustion occurs as a result of the compression of the air to a temperature sufficient enough to ignite the fuel. There are several similarities and minor difference between the C.I engines and the gasoline powered engines(spark ignition engines,S.I engines). The components such as the crankshaft, camshaft, piston,valves etc they both share in common.  The same cycle of operation governs both for the four stroke and two stroke engine process. However the diesel engines can easily be recognized by the absence of the ignition system and other factors such as Injection of fuel is done via an injection pump They are noisy and produces pollutants easily It produces more power and torque Overtime, diesel engines have received massive success in the construction of heavy duty trucks,construction equipment ,powe...

The value of the turbo charger in an automobile is unknown to a few engineers and its users, because they lack the proper knowledge on these points of the component itself. http://d3e98kcom2u4ch.cloudfront.net/wp-content/uploads/oldblog/2016/09/turbocharger-operation-diagram.jpg What is the value of the turbocharger? What is it made of? How does it work? Where can it applied? Likely problem encountered Ignorantly we think the main reason motor A generates more power,higher velocity,consumes less fuel, sometimes environmental friendly than motor B is because of the engine structure or size. But there is one way to improve an engine which is the turbocharger. The turbocharger is an exhaust-gas driven component of an engine that increases the volumetric efficiency of air in an engine in order to increase its power.  It consist of a casing,impellers and shaft. Generally, the charge[mixture of fuel and air] that flows into the combustion chamber produces the t...

Mechanical engineering  is a very wide discipline that, effectively, covers anything that moves.  Its breadth is due, in part, from its need to cover the design and manufacture of anything and everything in a moving system. This ranges from a system's smallest components to the completed, sometimes enormous, machine as a whole. Throughout history some  innovations  have come to define mechanics as we know it today, the following are no exception. These engineering innovations range from the any one of the classical 'simple machine' to complex concepts such as  flight . This list is far from exhaustive and in no particular order. 1. The Aeolipile Was an Early Steam Reaction Turbine The  Aeolipile   was the world's first rotating steam engine or more technically correct, a steam reaction turbine. It was devised by the great Heron of Alexandria in the  1st Century AD  and described it in great detail in his book  Pneumatica . ...

Weather forecast instruments are a vital component in our application of science and technology in an attempt to predict future conditions of the atmosphere for a given time and location.  This article will help you know the basic weather forecast instruments and invention which aids scientist in reading the weather today. 1. Pyranometers Measure Solar Irradiance Pyranometers  are a special type of weather forecast equipment used to measure solar irradiance on a given planar surface. They are also designed to detect and record solar radiation flux density  (W/m2)  within a wavelength range of  0.3 to 2.8 micrometers . They have become the World Meteorological Organization's standard instrument and are covered under the International ISO 9060 standard. Such devices tend to be calibrated using the World Radiometric Reference which is maintained by the World Radiation Center in Switzerland. Pyranometers tend to comprise of following main components: ...
