The EGR system routes many of the exhaust gases (6 ? 10%) through the EGR valve, last on the Intake System, and in the end in the combustion chamber. The exhaust gases are inert i.e. they don't burn within the combustion chamber; also, the exhaust gases use up a number of the space which could preferably be taken with the intake air. This decreases the volume 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. "And I saw three unclean spirits like frogs come out of the mouth in the dragon, out from the mouth with the beast, and out with the mouth with the false prophet. For those are the spirits of demons , performing signs, which are in the market to the kings in the earth and in the whole world, to assemble these phones the battle of the great day of God Almighty." Rev. 16:13,14. (It's the battle of Armaggedon - [see verse 16], that involves the worlds leaders [vs 14] and comes about after time, as Jesus announces He is planning to return [see vs 15]). The automobile is really a complex machine comprised of different components each which has a specific role. Fuel is processed inside the engine where it really is changed to souped up that moves the vehicle. Exhaust in the combustion process is filtered to render emissions less unhealthy for environmental surroundings. The transmission system feeds more capability to the engine for the automobile to boost its acceleration. Glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears. Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness. Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation. Glasses are worn for eye protection in some sports, such as squash. Glasses wearers may use a strap to prevent the glasses from falling off during movement or sports. Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses.
