my fast business strategy with the current economic stuation people do have capital so am services or products other person who is studying not just to have a job however with extra ordianary information or ldeas of creating opportunities to people looking for work: in africa everyone is only tought to become job hunters then when they graduate they start searching for job thus why there high rate of unemployement and so the youth focus there bleme towards the government not to the one who designed the teaching sybus and also you see the youth demostrating on the streets becouse of unemployment : 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.
