Variable Geometry Turbocharger Turbochargers works on the simple principle of increasing the intake air density by compression. Being able to fill more air into the combustion chamber will allow more fuel to be added to produce more power. However the operation of the turbocharger relies solely on the exhaust gas velocity to drive the compressor. Thus the compressor will be at optimum operation range when the engine is under heavy load. When the throttle is opened‚ it will take a certain period

The spectrums of oil spill issues are diverse and large. They range from environmental issue to economic‚ ecological‚ ethical‚ politics and policies. Among many other oil spills‚ the BP oil spill in the Gulf of Mexico‚ occurred on April 20‚ 2010 was recorded as the greatest environmental disaster in our history (BP leak the world’s worst accidental oil spill‚ 2010). The goal of our research is to seek possible solutions to reduce the risks of offshore oil spills. To attain this goal‚ we gathered
