A small truck has a four-cylinder, 2.2-liter CI engine that
operates on an air-standard
Dual cycle using light diesel fuel at an average AF = 21:1. At a
speed of 2500 RPM, the
engine has a volumetric efficiency is 92%. At this operating
condition, 0.4% of the
carbon in the fuel ends up as soot in the exhaust. In addition,
there is 20% additional
carbon soot from the lubricating oil. The amount of soot is then
increased by 25% due...
