The Physics of a Diesel Engine Essay -- Energy Automobiles Essays

The Physics of a diesel motor Engine The knowledge base we live in is surrounded by diesel locomotive engines. They are on the freeways, railways, air outways, and are one of the leading electricity producers in the world. They are likewise becoming more popular in automobiles. These engines are efficient and safe and they are getting very sophisticated. However, the natural philosophy behind these engines has not changed.By way of definition, courtesy of Diesel EngineEngineering a diesel engine is an internal burning engine in which the chemical energy of provoke is transformed into thermal energy of the piston sleeping accommodation charge, in consequence of the self-ignition and blaze of fuel in the engine cylinder after compression of the air charge in the cylinder (p1 Makartchouk).There are basically devil types of diesel engines, two-stroke and four-stroke. In a two-stroke engine the piston is forced from the covering of the cylinder by the expanding air fuel mix ture. Before the piston reaches the so-and-so of the cylinder the used mixture, (called exhaust), is forced out of the cylinder by the inflowing fresh air. The fresh air relies upon a blower, air induction system, to push it into the burning chamber. During this time period the piston begins to travel to the top of the inning of the cylinder and compress the fresh air sufficient to raise the temperature in the combustion chamber, (area between the top of the cylinder and the cylinder head at top dead center), to 1000-1200 degrees Fahrenheit (p12 Dagel). The fuel is then injected under pressure into the combustion chamber, the air ignites the fuel and the gases begin to expand finishing one cycle.A four-stroke engine begins the same way as the two-stroke with the expanding gases pushing the piston downward, called the ... ...n chamber rises dramatically. The combined fuel and air molecules bounce off one some other and since the path of least resistance is the piston, the pist on moves downward creating mechanical work.Applying physics to something in everyday use creates a new appreciation for what real happens when you step on the accelerator pedal or see a truck pulling 40,000 plus pounds up a steep incline. With even up a basic study of physics my worldview has changed. I now go to at that cold piece of cast iron sitting in an engine compartment on a molecular level.
