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. When tractors were first developed, they used enormous steam engines that were notoriously unreliable and hard to maintain. These were phased out around the turn with the twentieth century and substituted for internal combustion engines which were smaller though powerful and ran on a number of fuels including kerosene, ethanol and gasoline. By the 1960s several of these engines were phased out and only more effective internal combustion engines that ran on diesel and after this, biodiesel.
