an easy task and will never be. The research I conducted on diesel and gas engines was unique, the things I experienced with job shadowing was unique, and the success and struggle with my project was outstanding. A gas engine is “a type of internal-combustion engine using a flammable gas, such as coal gas or natural gas, as fuel” (Collins English Dictionary). A diesel engine is “an internal-combustion engine that uses the heat of highly compressed air to ignite a spray of fuel introduced after the start of the compression stroke” (Collins…
compressed air and their engine parts are built stronger than traditional gas engines parts. Everyone should own a diesel vehicle over a gasoline vehicle because diesels are more fuel efficient, have more power, torque, and more reliable. Diesel engines provide more power using less fuel compared to gasoline engines. On average, a "Diesel engine advantages about 20-30% better fuel economy than similar vehicles with a gasoline engine" (4 benefits of buying). Diesel vehicles get "6 to 8 more miles…
Diesel technicians are frequently the highest paid on a dealership lane, and get paid just as much if not more than most computer programming jobs as well as much more. Diesel engines contribute to about 52% of the vehicles on the road today and that number is only expected to go up. As the amount of diesel vehicles go up, the demand for technicians to work on them will raise as well. Not only do diesel engines interest me, but engines in general. So the time for me to pursue my career is…
specific heat capacity are ideal. Chemical effect The Chemical effect can affect and alter the combustion temperature due to chemical reactions taking place between the gases. One typical example is the consumption of heat of heat during endothermic reactions such as the dissociation of CO2 and H2O. Comparing all four combustion effects, it is noted that most of the NOx emissions reduction from CO2 comes from the dilution effect with an additional effect due to the chemical effect. The Thermal…
MAGNETIC COMPASS - one of the simplest of all instruments and is one of the oldest TACHOMETER – Indicates the RPM of the engine. COMMONLY USED SYNCHRO SYSYEMS * DC Selsyn System * A coil od resistance is wound around form, and two wipers are driven by the device whose movement is being measured. * AC Magnesyn System * An AC remote-indicating system that uses permanent magnets for the moving elements and toroidal coils wound on highly permeable ring type cores for the…
rockets. The purpose of this project is to see if a homemade Chemistry Rocket, fuel made of baking soda and vinegar, can equal the endurance and/or the height of a Hobbytown Rocket. Though it is important to know the history of rockets and how they function, and the proper gear to wear even around small scale rockets in order to properly carry out this experiment. The first real rockets were invented by the Chinese as early as the year 1232 A.D (Bellis 2). These rockets were used mostly…
Theory: Boyle’s Law states that when temperature (T) is kept constant, pressure (P) and volume (V) have an inversely proportional relationship. Boyle’s constant (B) can be expressed by V=B/Pwhere volume is (in this lab) cm^3 and pressure is in atm. Charles’ Law states that when pressure is held constant, temperature and volume are directly proportional. Charles’ constant (C ) can be expressed by V=CTwhere volume is in cm^3 and temperature is in Kelvin. Gay-Lussac’s Law states that when…

D., 2002, “Modeling of Engine Cyclic Variations by a Thermodynamic Model,” SAE paper 2002-01-2736. Ji and Ronney (2002) developed a Kantor model showing that prior-cycle effects resulting from exhaust gas residuals are a significant factor in cyclic variability of combustion in internal combustion engines.

Description of the proposed heat release rate model. The cylinder gas is considered as a spatially homogeneous thermodynamic system occupying in a single zone for the compression, expansion, intake, exhaust processes and two zones (burned and unburned zone) for the combustion process. The instantaneous composition of cylinder gases are obtained from the mass fraction of fuel burned. The instantaneous thermodynamic properties are computed by the established equations [20-21, 28]. The…
Introduction: Photosynthesis is the process used by plants, algae and some bacteria, to use the energy from the sunlight to transform carbon dioxide and water into glucose and oxygen. The equation for photosynthesis is: carbon dioxide + water light energy glucose + oxygen. Chloroplasts are an organelle found in the leaves of green plants and are essential in photosynthesis as they are responsible for producing the glucose and storing the energy. Photosynthesis is vital for all life on…
