Between June 25 and 26, 1876, a combined force of Lakota and Northern Cheyenne led the United States 7th Cavalry right into a battle nearby the Little Bighorn River in what was then the eastern edge of the Montana Territory. The engagement is famous by several names: the Battle of Greasy Grass, the Battle of Little Big Horn, and Custer's Last Stand. Perhaps the most famous action in the Indian Wars, it was a remarkable victory for Sitting Bull and his forces. They defeated a column of 900 men led by George Armstrong Custer; five of the Seventh's companies were annihilated and Custer himself was killed inside engagement in addition to 2 of his brothers as well as a brother-in-law. Known as the battle that left no white survivors, Little Big Horn has inspired a lot more than 1,000 artwork, including over 40 films. Here are four of the best... The EGR system routes a number of the exhaust gases (6 ? 10%) over the EGR valve, in for the Intake System, and finally inside combustion chamber. The exhaust gases are inert i.e. they cannot burn within the combustion chamber; also, the exhaust gases take up many of the space which will rather be taken from the intake air. This reduces the level of intake air available for the combustion process during each Power Stroke; which experts claim decreases the peak combustion temperatures. This leads to lower NOx emissions.
