what year did the battle of saratoga happen

Between June 25 and 26, 1876, a combined force of Lakota and Northern Cheyenne led the United States 7th Cavalry in to a battle near the Little Bighorn River in what was then the eastern fringe of the Montana Territory. The engagement is well known by several names: the Battle of Greasy Grass, the Battle of Little Big Horn, and Custer's Last Stand. Perhaps the most well-known action in the Indian Wars, it absolutely was a remarkable victory for Sitting Bull and his awesome forces. They defeated a column of seven hundred men led by George Armstrong Custer; five in the Seventh's companies were annihilated and Custer himself was killed in the engagement together with two of his brothers and a brother-in-law. Known as the battle that left no white survivors, Little Big Horn has inspired more than 1,000 pieces of art, including over 40 films. Here are four of the best... The EGR system routes a number of the exhaust gases (6 ? 10%) through the EGR valve, back in for the Intake System, and finally inside combustion chamber. The exhaust gases are inert i.e. they do not burn inside the combustion chamber; also, the exhaust gases occupy a few of the space which may otherwise be taken from the intake air. This cuts down on level of intake air readily available for the combustion process during each Power Stroke; which often decreases the peak combustion temperatures. This ends in lower NOx emissions.
