Diesel Fuel Properties and Exhaust Gas - Distant Relations?

This paper examines the question of whether or not significant improvements in the condition of a diesel engine's exhaust can be practically achieved by altering the quality of the fuel. Engine test results from a variety of investigations are presented, and they are examined on a fuel quality/exhaust quality basis. Black smoke, white smoke, odor, oxides of nitrogen, and carbon monoxide are the exhaust constituents discussed in conjunction with fuel volatility, viscosity, and ignition quality. It is suggested that a change in base fuel quality is not, at present, a practical means of insuring an improvement in exhaust condition.
