what does the word locomotive mean

The EGR system routes a number of the exhaust gases (6 ? 10%) from the EGR valve, last on the Intake System, and ultimately within the combustion chamber. The exhaust gases are inert i.e. they cannot burn in the combustion chamber; also, the exhaust gases take up a number of the space which would preferably be taken with the intake air. This reduces the volume of intake air readily available for the combustion process during each Power Stroke; which in turn decreases the peak combustion temperatures. This brings about lower NOx emissions. 7. Using distractions If you think that avoiding drinking throughout the workweek but spending an evening in the party at weekend drinking a lot is not any matter, your idea is not true. You can consume over 1,000 calories from drinking (wine, beer, soda, etc) and eating (chicken wings, pizzas, peanuts, etc). It means you will get extra unexpected pounds.
