Therefore, when shooting in macro, it is easy to get a shallow depth of field if utilizing a large aperture.

If you use a 100mm macro lens to shoot the insects' close-up, even with the F13 aperture, the depth of field is extremely shallow, and sometimes need to utilize the manual focus function to carefully adjust the focus position to spotlight your eyes of insects to make the image more vivid. Between June 25 and 26, 1876, a combined force of Lakota and Northern Cheyenne led the United States 7th Cavalry in a battle close to the Little Bighorn River with what was then the eastern edge of the Montana Territory.

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.
