A combined fascination with wildlife and trains may be covered on this 2 mile walk. From Totnes Railway Station, the sight of steam doing his thing, a stylish route makes its path along the River Dart to Dartington. Once at Shinner's Bridge you may enjoy a nicely earned rest with the Dartington Cider Press Crafts Centre and Caf. This route is suitable for everybody of any age and talents including wheelchairs 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.
